    I spent a lot of time researching and interviewing multiple locations; I finally landed on underground fitness, and I'm glad I did. I had David Forbes as a personal trainer and couldn't have asked for a better coach. He was exceptional. Not only did he help me perform workouts with proper form to reduce strain on my body, but he also gave me great tips on tracking calories and techniques for maintaining goals. The Gym itself is immaculate, has excellent equipment, and is non-crowded. I would highly recommend underground fitness and David Forbes.

    Love this gym and staff! I have been a client of Ron Edwards for over 2 years and am constantly engaged and challenged in my workouts. He takes the time to tailor my sessions to my needs and changes my routines so I am not bored. I am so happy with the changes that I see, and the leaps I have taken in my fitness. You won't be disappointed.

    Ron is an amazing trainer. He is my favorite there. The staff makes you feel welcomed and comfortable. I was nervous and intimated going in but the staff and people working out made me feel at ease. Definitely the best gym in phoebix, I highly recommend Underground Fitness!

    This gym is AWESOME! The staff is amazing, especially Ronald! He is the best at what he does and is able to find creative ways to work every part of your body and make it fun (until the next day ha ha). He also has some great advice to give to make eating healthy a lot easier and enjoyable. I highly recommend working with him and the other trainers at Underground!

    I've been a client of Underground Fitness for nearly two years and it's an integral part of my fitness plans. With Ron I've met goals and set more aggressive ones. He's helped me accomplish more than I thought I was ever capable of...and he makes it as fun as it can be (running up a mountain in a 50lb vest will never be fun fun).

    Trainers are all great at underground! They know exactly what they are doing and the best way to do it. The experience is unlike any other. Because of my trainer Ronny I was able to bulk up and achieve the goals I had set for myself.

    I’ve been a member of Underground Fitness for over a year now and I must say that my experience has been great. When I initially joined, the convenient location near my house was what caught my attention, but what has kept me committed and here is the awesome training from my trainer, David. David is truly one of the best trainers I’ve had the privilege to work with. His ability to push me beyond my limits while still understanding the nuances of my body’s capabilities sets him apart. He tailors my workouts to match my fitness level and consistently challenges me to work harder. His knowledge of different exercises and techniques ensures that each session is dynamic and effective. The atmosphere at Underground Fitness is pretty basic, with standard equipment and a supportive community of people who are looking to get or stay fit. But it’s David’s dedication and personalized approach that have made me a loyal member. If you’re looking for a fitness center that goes beyond just giving you equipment and provides a tailored experience that holds you accountable I highly recommend Underground Fitness.

    I started working out at Underground last summer with a groupon. I loved the trainers and the atmosphere so much, when my groupon expired, I signed on. I was assigned to Joey and he is awesome! I need supervision and I need to be held accountable, otherwise I won't work out. Underground is great at that, and I really love how they always make sure you are eating right and give you nutrition tips. At one point, after an event put me financially behind, I tried to quit. The manager, Ron, let me know how great my progress was and worked out something that fit my budget until I could catch back up. It really made me feel valued. I've never worked out consistently this long -- it's been over a year! I work out at least 3 times a week. My coworkers comment on how fit and toned I look, and I'm stronger than I've ever been. At 37, my metabolism isn't what it used to be, so I'm so glad I found Underground Fitness. Also, I have significantly lowered my cholesterol without taking medication and I KNOW it's because of the healthy habits I've gained through my program. Thank you, Underground Fitness!

  • 5/5 Christopher Y. 8 years ago on Google
    I've been a client of this gym since January 2015 and I have to share how supportive, knowledgeable, and encouraging this place really is! I'm not athletic by any stretch of the imagination, but my trainer, Ron Edwards, pushes me just the right amount outside my comfort zone so that I'm continually challenged, but never discouraged. On top of his great guidance, the entire team is friendly - they really do get to know you by name. My sessions are semi-private (there are several other clients working at the same time), and Ron makes sure he gives everyone just the right amount of one-on-one time without hovering or getting in the way. The group I'm with and even clients outside the group make this a fun place to workout (I never would have thought I'd say "fun" and "workout" in the same sentence!). Highly recommended!

  • 5/5 Erik J. 2 years ago on Google
    I joined Underground Fitness a couple of years ago with the hopes of getting back into shape after years of not working out. The trainers recognized that I needed to start slow to rebuild the muscle that I had lost. Additionally, they were very diligent to teach proper form in an effort to reduce injury. I am happy to report that I am now stronger than I have ever been. I highly recommend Underground Fitness for the quality of the trainers, available equipment and the clean workout environment.

  • 5/5 Madison Y. 1 year ago on Google
    I’ve struggled keeping myself accountable and actually staying on workout plan for awhile now (which I’m sure many ppl can relate). I tried multiple bigger gyms and I always got intimidated, didn’t know where to even start, and I would go for a week and then just slowly stop going. I wanted a smaller local gym that could help me stay accountable and help me reach my fitness goal and Underground fitness has done just that. My trainer David is super nice, knowledgeable, and definitely pushes me to reach my max potential! :) I’m almost a month in and I’m already feeling better and stronger. Would definitely recommend to anyone at any stage :)

  • 5/5 Tiffany S. 2 years ago on Google
    I finally decided that the only way for me to change my lifestyle was to get a personal trainer to hold me accountable and teach me all I need to know to work out in the gym since working out at home led to too much inconsistency. I'm so glad that I found Underground Fitness! They are a personal training only gym and also offer nutrition coaches if you also need help with changing what you eat to be more healthy. I signed up for the 9 week program with a personal trainer and nutrition coach, which greatly helped me change my outlook on fitness and nutrition. I then signed up for an additional 13 weeks of personal training only. I now feel confident to get a gym membership and do this thing on my own. I truly have experienced a lifestyle change. David was so great to work with as my trainer and he pushed me to do things I never thought I could do. Thanks Underground Fitness for all of your help! 💪👏

    Great trainers! Super knowledgeable and friendly. Results focused on reaching your goals. All staff and trainers conscious of safety and education of proper techniques. Would recommend. Trainer Matt was awesome, personable and focused. Sessions went by quickly and variety of different workouts with a good mix of cardio and strength.

    If you are looking for truly personal training, this is the place to go. This isn't a regular gym where they do personal training on the side - personal training is all they do - and they do it well. My trainer works with me to achieve my personal goals and keeps an eye out for form and flexibility issues. Great environment - clean, friendly, and professional.

    These guys are great. With the challenging exercise and nutritional advice I've had from Joey I'm down nearly 30 lbs and in probably the best shape I've been in for decades. They are all friendly and helpful. You won't be disappointed.

    I've been going here for almost 2 years and love it. The trainers are the best and always have new and fun fitness classes. I broke my foot about a year ago and they have been wonderful working through the injury. I worked out the entire time I was in a boot - they modified all the exercises and brought weights to me! Come join us for the 5:30 am class.

  • 5/5 Dinh L. 3 years ago on Google
    Before joining Underground Fitness, I was not eating well and working out as consistently as I needed to which lead to unachievable results. I was not serious about eating healthy and my lack of commitment to working out on my own created fluctuations in my weight. The lack of results lead to constant frustration which would lead me to quitting and giving up. Ever since joining Underground Fitness, I have been able to get closer to achieving my goals. Ron has helped me develop a greater knowledge about dieting and counting macros and. Through my workout program, I have also tracked my daily goals, (making sure I eat all my meals, working out in the morning, making sure I squeeze time to meditate), small daily goals to achieve to make sure I am having a productive day. My trainer has helped set me up with workouts that are designed specifically for my goals such as weight loss and toning my body. Since joining Underground Fitness I've lost a desirable amount of weight. I have noticed changes like more muscle gain as well as getting toned abs. I am very glad I joined this gym as they have helped me stay motivated in achieving my goals and holding me accountable for it. Since working out, I have more energy throughout day, I sleep better, and I am eating better. I would highly recommend this place as they have helped me become more successful in my weight loss journey and creating better daily habits for myself.

    Great gym and great trainers! The group classes are motivating and the trainers keep them challenging and interesting. Ron, Jake, Joey, Danielle, and Braden are all very knowledgeable and able to suggest modifications as needed. I especially like trainer Braden's style, he seems to have an endless number of exercise variations and keeps everyone motivated and smiling throughout the workout! Highly recommend for those looking to get away from the huge gyms and go someplace where the staff are friendly and knowledgeable.

    Underground Fitness has been great for our adult, special-needs son. At the initial appointment, Ron's understanding of Autism was quite apparent. Roxanne has been doing the bi-weekly workouts with Jeff, and he is doing well working with her. Jeff told me, "The staff are so kind to me and so are the other people (working out at the same time). I don't think I could go to a place that doesn't have a trainer." I appreciate Underground Fitness's willingness to accommodate Jeff's sensory needs by lowering the music volume and adapting work-out routines for him.

    Ron, Kelsey and the rest of the Team at Underground Fitness North Central are just AWESOME. They've been kicking my mom bod back into shape for almost a year. I still have a ways to go but I know I'll get there with these tough trainers breathing down my neck and holding me accountable to the commitment I have made to myself. Kelsey and Ron are flexible and accommodating with my busy schedule as an attorney and mother, have helped me establish a personalized nutrition program, and regularly check-in to see how things are going. And, there are always lots of laughs to share with and words of encouragement to receive from the wonderful community of members that belong to the gym.

    Underground Fitness is amazing! I love this gym, and have been going to the 7th street location for years. I like that the owners and trainers know all the clients by name. The trainers are amazing. I never do the same workout twice, and they are always challenging. Best gym around for sure!

  • 5/5 Bella D. 2 years ago on Google
    Before I started with Underground Fitness I was having a hard time building up strength for swim team. At the beginning, builging up that strength was difficult but Kelsey helps that by going at your pace and keeping you accountable. I have already noticed changes in how I am swimming faster since starting training and how the different muscles in my body are getting stronger.

    What was the problem you were having before you started with us? Finding a normal and healthy eating schedule with my crazy work schedule. What did the frustration feel like as you tried to solve that problem? I was not eating hardly at all but when I would eat it was all junk. What is different about your journey this time? Ron has helped me nutritionally more than I thought he would finding meals that would get me through the day without losing muscle mass What kind of changes have you seen already in your journey? Definitely my energy and eating habits have changed a lot. How is it impacting your life? I’m still struggling with my work and eating schedule but it is way better than when I started and I myself and friends can see changes.

  • 5/5 Peter D. 3 years ago on Google
    It's all about results. I have had training before but without quite getting the dieting part right and not working out enough on my own. With the nutrition plan here I saw all those benefits I'd always heard of but never experienced myself. I had to make more ambitious weight loss goals pretty quickly. At home I found myself wanting to work out more to achieve more in the gym. I have worked past weaknesses and now feel on top of my limitations. Can't praise this place enough. Awesome trainers and some cool fellow trainees as well.

    In the past 5 weeks I have noticed a big change in my strength and physique. The personal trainers Kelsey and Rob are brilliant at what they do. They will size you up based on your sport and goals, creating a personal Workout Program/meal plan that will get yea what you need. Plus the payments are very flexible.

    Kelsey is my trainer. She is very skilled at her job. I am 70 and she designed me a workout that is challenging yet realistic. I had an injury unrelated to the workout and she adjusted accordingly. She is flexible with my schedule when needed. She is obviously very experienced and I trust her expertise. I highly recommend her.

    Underground Fitness is amazing! I have had gym memberships at various big box and boutique gyms and I will never go back. The safety protocols they implemented at the height of the pandemic was what drew me to them. The quality of their services are what keeps me coming back. I have had many excellent personal trainers over the years. Roxanne is the best trainer I have ever worked with. When I think I've given my all she manages to coax even more from me. If you start with Underground Fitness you will never want to leave.

    I have been attending Underground Fitness for about 2/3 months and after training with other trainers in the Valley this is by far the best experience I have ever had. I train with David Forbes and he is amazing. I can see changes to my body every week and the strength and discipline I have gained has changed many aspects of my life outside of the gym. I’m blessed to be able to train here, Underground Fitness is the place to be.

    We’ve been working with Roxanne for a year and a half and we couldn’t be more thrilled. We are not your typical “gym rats” but wanted to get stronger as we aged to prevent falls and injuries. With her, we have achieved goals we didn’t think were possible. She is so encouraging and a delight to spend time with. The gym is very well equipped, always clean and everyone there is super-friendly. Highly recommend.

    Staff is welcoming and friendly. Joey (trainer) is great! He has always been professional, knowledgable and flexible with my often difficult schedule. My only complaint is UF's vanilla taste in music. I prefer death metal, cursing and mysoginsyic lyrics during my workouts.. Other than that this place is great!

    I have been working out here with Camille for going on 5 months now and it's been the best gym I've been to. I couldn't ask for anyone better than Camille. The trainers here truly care about you and push you to be the best that you can be. They have changed my life and it only keeps on getting better. If you want to change your life for the better and are willing to push yourself this is the best place to go. Personally I have made great strides in the short time I've been here and I can't wait to see even more progress!

    A transformative experience! From the beginning consultation with Ron, to meetings with Christina, their registered dietician, to training with the best of the best, David, I have absolutely loved each element of this experience. My stress levels have decreased, I feel stronger each week, and I genuinely love working out. Cannot even fully express how fantastic of a trainer David is! Every other trainer and client is incredibly kind and hardworking as well—the atmosphere is so positive! This has been such a rewarding process, and I'm thrilled to continue training here!

    Started Underground Fitness September 6. Just turned 60 and I thought many times about working out but never started. Finally I contacted the perfect place.Underground Fitness I meant with Ron not knowing a thing about how to get started Ron explained everything about Underground Fitness and the program I would be doing. David is my trainer and working with him is amazing. David knows what works best for me. David has a lot of knowledge of weights and fitness. It’s October 23 and what a change. I feel like a new man. Toning up and gaining muscle plus with the help of my nutritionist Christina I know what to eat and portion size. I am down 2 jean sizes I am still working out and getting fit week by week. I am a new person i feel amazing. I encourage everyone that is wanting to get fit and enjoy life join Underground Fitness. Ron, David and Christina really go out of their way to listen and they are the reason I am getting fit and turned my life around.

    I live in downtown Phoenix and I drive 25 minutes three times a week to go to this gym. There are closer gyms but I am so glad I joined this one. David is an excellent trainer and knows exactly how to push me in a positive way while also, somehow, making it fun. The environment is extremely welcoming and the overall vibe of the gym is terrific. Highly recommend.

    These guys are great! The trainers all know you on a first name basis and work with you towards whatever goals you have. They are always willing to help you modify exercises if needed. I have been going to Underground for about two years and they still keep exercising interesting by switching things up all the time. Braden is a wonderful trainer and very knowledgeable. All of the trainers are happy to answer my specific questions and are attentive to my needs. Great place to work out!

    Would give this place 10 stars if I could! Training at this gym has been a great experience- very educational, motivational, and challenging. The trainers are all amazing: Scott, Ron, Lance, Larone. I have been out of the gym for some time and was nervous to start back again, however, the trainers made it a smooth transition by customizing the diet and workouts to meet my schedule and individual needs so that it was do-able yet challenging and results producing. You can tell the trainers care and love what they do. A lot of their clients have been going for years and consist of all ranges of ages, fitness levels, and abilities which makes it a comfortable and encouraging place to work out. Best gym I have ever been too! I cannot recommend it enough.

  • 5/5 Robbi L. 8 months ago on Google
    I was the 73 year old, sedentary, frail widow who decided it wasn’t too late to make a major change in my lifestyle. I spent months investigating gyms, yoga studios, different modes of exercise programs and finally found a trusted connection. Tucked in the southwest corner of 7th St & Mountain View is a petite building that houses Underground Fitness. Yes, good things come in small packages and even better are the big results from their expertise. My trainer, Roxie, does more than just instruct, she demonstrates and explains each exercise. I feel safe as she optimistically cheerleads me through activities using a wide variety of equipment. Even my friends have noticed my improved endurance, stamina, and toning. Underground Fitness is my get-fit., feels like home, personal gym. I’m optimistic about reaching my goals and setting new ones.

    This was the first time I stepped into a gym in nearly 20 years which can be intimidating. I have been working out with both Roxanne and David with the goal of building strength and muscle mass and they have already helped me significantly with getting those goals. They are big on proper lifting technique too which was important to me to prevent injuries. I actually enjoying waking up and going to get my workout in and the mornings. All of the other members of the gym also make for a great work out environment.

    Fantastic gym- I’ve been working out with Roxanne for about 6 months now with the goal of building up over all strength to help with aches and pains from work. Each workout was specially catered to me and my goals and I was met with nothing but encouragement and education that will be able to apply to my fitness journey for life. Roxanne is so professional and thanks to her I truly enjoy waking up early and bettering myself.

    While I needed more than a “quick transformation”, I can’t say enough good things about this gym and their trainers! They honestly listen to what you need, and give you just that. This gym removes all the barriers you have to making real progress, real stamina and strength gains. Never over crowded. You can’t go wrong with Roxanne or David (and probably the others as well). This place is worth your time and effort!!

    I bought a Groupon last November because I wasn't sure if would like it, but I loved it and have been a client for 9 months. Danielle is a great trainer and very motivating and knowledgeable. I work out in the semi-private training sessions, but still get dedicated attention and support. Not only have I seen an improvement in strength and endurance, but I actually enjoy working out now. The whole staff is kind and motivating, the other clients are supportive and nice and the facilities are super clean.

    This place is great. David Forbes oughta be given some sort of personal training Medal of Honor. David and the rest of the UGF staff are so courteous, knowledgeable and thorough. If anyone is looking to get back in shape, lose some weight, post injury, any fitness related reason at all, look no further.

    I joined this gym about a year ago. I first met with Ron who went over all the logistics and how the pricing was structured. I loved that he was not a hard sell and was genuinely interested in what my needs were. I signed up and have been working with my personal trainer Dori for a year now. Dori, by far is the best trainer I’ve ever worked with. She is very professional and extremely knowledgeable at what she does. She gears my work out to my needs and what I’m working on personally. I have had a couple injuries and she has been able to modify my program so I can continue to work while healing myself. I would highly recommend this gym to anyone who is looking for a personal trainer.

    David is a great trainer! He knows just how far to challenge me to see progress yet not so hard that I feel frustrated. He is able to adapt exercises as needed. David motivates me to do my best and celebrates in my accomplishments! So glad to have found Underground Fitness and to be paired up with David!

    Underground Fitness is a great place to start working out. Ron, the director, is a wonderful communicator and will work with you should any questions or concerns arise. I've been working with Matt Guzy as my trainer, and I never in a million years thought I'd say this, but I genuinely look forward to my workouts with him! Matt designs a workout for right where my current level is at, and they are always different and interesting. I deeply appreciate what he has planned, his explanations & demos on the exercises, his ability to hear me out, and his keen eye on how my body may not be in the best form, and then providing adjustments. Should you be new to working out or personal training, I highly recommend Underground Fitness.

    Roxanne is a great trainer! She is knowledgeable, friendly and professional. She pushes me within my limits and she is very encouraging. I feel safe that she will protect my past injuries from re injury and I'm feeling stronger and healthier already and looking forward to continued results. The gym is very clean with nice equipment. I like that it's not a huge, crowded place and there's lots of professional and personal attention. Abby

    I joined Underground Fitness in the beginning of October 2020 to lose weight and get toned again. My trainer has been Kelsey and Ron has provided me with weekly nutritional guidance. I started the program at 221 pounds. After two months of working with them, I'm done to 201 pounds. The exercises are challenging, but not overwhelming. Kelsey has done a fantastic job of constantly changing my exercise routine; I new do the same sets of exercises day-to-day. I'm amazed how fast my one hour sessions go. Kelsey keeps me engaged during it session that, before I know it, the hour is up. Ron has done a remarkable job of guiding my nutritional habits. I've been so pleased with them that I signed up for another two months to keep my momentum going. When I first started, Ron spent a good hour with me discussing my fitness goals, medical history, and past workout history. From there he was able to extrapolate a general outline that Kelsey has used to create my daily workout routines. As they're told me, it took a long time to gain the weight, and so it takes time to lose the weight. I've pretty much averaged loosing two to three pounds each week. I highly recommend Underground Fitness to anyone who are serious about their health and wanting to achieve their fitness goals.

    I've been a client of Underground Fitness for the past several months, and they are without a doubt one of the best fitness and personal training companies in Arizona. Everything from the Nutrition Counseling, to the workout regimens and goals they set are top-tier, and the coaches are effective, and a pleasure to work with while meeting the goals that you have set. They take the time to explain what you are doing, and why, and are extremely attentive to help you with form, and ensure that you get a great workout that helps you meet your goals. Not only do they build custom workouts to help you meet your goals, but they also take the time to show you how to do them, and tell you why and the benefits. They show you how to properly exercise and plan your nutrition so that you can exceed your goals and be extremely fit. Throughout my time, I have put on a significant amount of muscle, and identified issues in my form that allowed my overall health to improve immensely. I highly recommend the team at Underground Fitness.

    This place is awesome! Shout out to Chris for taking a lot of time to evaluate my strengths and weaknesses and develop a plan for me to meet my goals. I am not a fan of big gyms and that is why I love Underground Fitness. This is a very comfortable place to work out and not feel the least bit intimidated and get the one-on-one attention to get me on track.

    Camille is a great instructor who works with me, give me that push and encouragement I need to meet my goals.

  • 5/5 Annemarie G. 4 years ago on Google
    By far one of the best gyms I've ever been to. Camille is an amazing trainer who is always there to motivate you and give you a great workout. Ron just simply sold me from the beginning of our first appt. He was all about understanding what my goals were and ensuring that I had started the program right. I highly recommend

    After many years of trying to find something that would not only fit with my schedule but also my goals I stumbled upon this place. If you are looking for something different then a normal gym with out the "GYM" personalities then this is your place. I met with Ron to go over my goals and needs and what they are able to offer and he was great, I was assigned to Dan so be my coach and have had a great time both learning new things as well as appreciate the support needed to not dread going to an appointment. I am not one to write reviews on places, they either keep my business or lose it. I have to say that I am so far very happy with the team.

    I have been working out here for a few months and have loved it! Underground Fitness is an awesome, stress free environment. My trainer, Camille, is super knowledgeable and motivating, helps you move towards your goals but also is very considerate of limitations, previous injuries, etc. I have seen & felt such a difference already and am excited for continued progress!

    Camille is an excellent trainer and really cares about your health and helping you achieve your goals.

    I could not be happier being a member here. Camille is my trainer and she is awesome. I’ve met most of the other trainers and the owner and they are all the coolest people. It’s a really fun environment and my favorite thing is how it never feels crowded. I also love how they don’t just tell you what to do and move on but they explain to you what and why you are doing that particular work out. It is very encouraging. I never thought that I would look forward to going to the gym so much.

    I have been working with the team at Underground since November 2017 and from the first consultation, with Scott, I knew Underground was going to be different than any other gym I have been to. A lot of gyms make the claim of offering the true support, nutrition and mentoring, that is needed to reach your goals but they all have come up short for me. 5 months, with this awesome team, and I have lost 12 lbs, 5 percent body fat, and several inches. They have helped me truly understand how to fuel my body to get the best results. I could not be happier! Now to the best trainer there is…Camille. All the trainers here are great but Camille is just amazing. She has taken the time to really understand my goals and push me to reach them. She doesn't take it easy on me and I love that. I train with her a couple of times a week and then she has a really great booty kicking boot camp on Saturdays. Aside from the great training she's also just a really great person. She's got such a great heart and she cares about all of her clients. It's not uncommon for me to get texts from her in the middle of the day telling me she is proud of me or sending me information about how to better hit my macros. If you are looking for a gym that cares about their clients Underground is for you. Come to a Saturday boot camp and check it out! You'll see why they have the rating they do.

    The staff at the gym is friendly, professional and encouraging. I have been working with Trish for over a year and she is the best trainer I have ever worked with. A well deserved 5 stars to Underground Fitness.
