We attended an open gym for my daughter on Saturday at 10am for the first time. I am so pleased with how well the open gym was run and how kind not only the workers but attendees and parents were as well! There was 15 kids and three instructors. They made sure to give clear direction to all kids in a kind tone and taught them different course obstacles and then let them all try. After that the kids were allowed to use whatever was "open" while the instructors helped guide them. At the end, they played group dodgeball. The 2 hours was plenty of time and my daughter loved it.

I took my kids there as first timers, very inexperienced, and I felt they received little to no coaching or help. Some of the tasks were impossible for them to do and there was no help, zero encouragement, and no adjustments made until I said something. There were 2 coaches and only 4 kids in the entire place, yet I had to step in and say something to both coaches that my kids needed help, direction, and instruction and they got so little. The other 2 kids who were there were regulars and were very good. We certainly didn't want to hold them back with bottlenecks. My kids were so discouraged and left saying they HATED it and I can't blame them. Gripz should set up classes for beginners and provide actual coaching with friendly, hands on coaches who know how to motivate and encourage kiddos who are being brave and trying something new and out of their comfort zone, not set them up to fail and then walk away.

Great fun for kids. . Only issue they should separate kids by experience. At times to much waiting around. If a first time kid with zero athletic ability goes first on a course the other kids have to sit and wait. Or they should have the more experienced kids go first on certain cources. Most of the staff great.

My wife, two daughters and I had a great experience here. They were welcoming, friendly and our trainer Dave was awesome. I highly recommend this.

Gripz has been wonderful for our family. My kids have been going for a couple of years. We drive 45 minutes each way to get there because it is so worth it. Let that sink in. An hour and a half in the car with kids several days a week. Worth. The. Drive. The coaches are helpful and encouraging to all of the kids. I like how the open gym is structured and not chaotic with kids running around by themselves. There are are several obstacles/stations open to choose from at a time to ensure a coach is present and assisting. My kids love that they can choose. Every class or open gym is different and my kids love the variety. Definitely recommend.

I love this place, this place is amazing. As soon as I walked into gripz gym I felt welcomed. Dave trains me and Dave is amazing. Dave really knows what he’s doing when it comes to training and nutrition. I’ve been training with Dave for a couple of months and I already feel that I came so far, got stronger, and my technique got a lot better. He trained me for the tough mudder which I easily knocked out thanks to Dave, and now I will continue to go to him because I want to get better technique. I highly recommend gripz gym they’re great people.

I want do one to i hope i win

Love this place the staff is awesome Great job !!! From the Tansil's and Jackson's

Came for the first time today and it was great. David was so nice and helpful. First time and we'll be back.

We had a birthday party with 14 seven year old boys and it was amazing! It was well run, organized and kept the boys engaged and focused! The boys were sweaty and tired at the end of the 90 minute session! The facility was clean and the staff was friendly. We travelled 40 minutes for this party and would do it again!

I love gripz, it is very fun. I get a chance to do things that I would otherwise not be able to get out and do. I have watched American ninja warrior since it first came out, and always wanted to do the stuff on the show.

Gripz gym is awesome! Fantastic set up. Clean, friendly environment. Great for families and individuals. Many different obstacles. We went with a large group of teens who loved it! Therese and Ryan worked with our group and helped show us the obstacles. Everyone had a blast. We will definitely be back. I highly recommend this gym!

Very dope... intense workout

Amazing gym. Amazing people and an amazing atmosphere. My twin girls and I loved the gym and cant wait to go back.

Came to Gripz during an out of town visit trying to get a little ninja workout in. Had a GREAT time. Very friendly & helpful staff. I'd be here all the time if I lived in the Detroit area.

I took my fifth grade den of Cub Scouts here for our very last den meeting. We had the scouts, younger and older siblings, and some adults that attended the two-hour session. Everyone had an amazing time. The staff was fantastic and did an excellent job of coaching the kids through the obstacle course. There was enough variety of challenges to keep a first grader entertained, while leaving a few challenges untouched even by the adults. Awesome place! I would definitely return for another visit.

To say that we love this place is a huge understatement! The coaches are all so positive and encouraging, always looking out for the athletes' health and safety. Just like the sport of ninja, every visit is even better than the last! We appreciate you guys and keep up the great work!!!!

VERY CLEAN. Staff is great and listens to the kids. They also made sure they were safe.

Oh my goodness...these people are awesome. Attended a childs birthday party a week ago. The staff is amazing. My son was exhausted. The great thing about this gym is that it is for all ages.

I love Gripz gym! My son has A.D.H.D. By the time we get to Gripz his medication is wearing off. The coaches encourage him and help keep him focused on the task at hand. They make it fun for him and the other kids. Since we've joined Gripz my child has made incredible progress with his focus, coordination and working with others as a team! I highly recommend Gripz Gym.

Gripz gym deserves 10 stars! We celebrated my daughter's 10th birthday with 6 of her closest friends. Everyone had a blast, including all the parents. Thank you Gripz Gym for outstanding service and impeccable cleanliness!

I could talk all day about this gym. Their classes pump you up every time. I leave feeling great. You will never leave without an amazing workout. You won't find another gym this great, you will love every instructor.

Best ninja gym owners in Michigan! Staff and programming is top notch.

It's a clean and well kept environment as well. Gotta check it out if you haven't and you're looking to join a good gym.

My GD, 7, loves it! Shout out to the coaches who are kind and patient and know how to interact with the kids.

Came here for the first time for their kids (structured) open gym. Great staff and well organized gym. The staff were friendly, encouraging and hands-on. Kids had a great time! Definitely recommend.

This is a great gym! The Staff was all awesome as well. We went to a skills WNL competition they hosted here and we were very pleased! Comp ran on time for the most part and everything went smoothly! We will deff be back for upcoming comps this gym will be hosting!

I'd give 10 stars if they let me. Super clean facilities that is constantly changing. An excellent team of friendly, well trained coaches. Very reasonable pricing & super accommodating. Plus flexible schedules. Win-win for all 3 kids, which seldom happens.

Awesome experience. If you like rock climbing, parkour, or any other sport that makes your blood pump. Gripz will raise your expectations of what a good workout is.

Really impressed with this place. Love that they give the kids mini goals to work towards on their way to learning the equipment - really encourages growth mindset, which can be tough for kids. Also, the owner or whomever does their communications is very friendly and accommodating. Just wish it were closer to our home :-)

We were at an 80's themed wnl competition hosted by Gripz this weekend. They did an amazing job running the event! We loved the attention to detail of the 80's theme.

Great ninja gym. The staff are all amazing and so are the owners. The open gyms, classes and competitions have all been a lot of fun!

A great ninja gym. Develop skills like on the show American Ninja Warrior and get a fantastic fun workout. The enviroment is lime a second family. So encouraging and fun. Co.e check it out.

My daughter had so much fun at this place. This is a great place for a birthday party!! It's a welcome change and thoroughly enjoyable for active kiddos.

This place is wonderful! Always a great workout that is never the same. Trainers are awesome and push you to do better! Can’t get enough of this place.

Great staff. Fun classes!

My friend and I, who are by no means "ninja warriors", came in today. Dave and Ella were there and they were both amazing. It was a great workout but also really fun. It was the perfect mix of fun and challenging. I could see it being great for anything from a girls night out to hard core training.

Excellently priced classes for all skill levels - very welcoming environment and friendly staff.

Great place to get some energy out, have fun, and get something else out of your workout routine. Great instructor and staff.

Always great!!

What an amazing group of people running this gym. Mr. Malcolm was great with the kids. Very patient and engaging. We will definitely be going back.

Very nice place for kids. Recommended!

The work out, teachers, staff, shakes, everything is amazing.

What an exceptional group of people running this gym. Mr. Malcolm was great with the kids. Very patient and engaging. We will definitely be going back.

Amazing.. I brought a group of 70+ kids. They did stations with all groups. So well organized for a large group. Great for birthday parties also

Very enjoyable I love to swing from one obstacle to another even though I’m 50 but it is also good for all ages from 5 up

Went to a parent & kid ninja night. My son loved it so much he joined their Ninja Team. Our experience has been wonderful. The owner and staff are so friendly and encouraging. They know how to push you in a positive way, to make you give your workout everything you've got. And knowing that health is more than just working out, I love that Dave challenges my son to eat healthier. My son has thrived there (both physically & his self-esteem) in just a few months.

Love love love Gripz!! My son is obsessed and wants to go every day! All of the coaches are wonderful! The owners are super nice, too! They change up the courses for both adults and kids. Never boring. It always leaves my son begging for more time! Such a great and fun place!

Really great for a one or two time visit if you are not interested in being a professional.

Super fun Ninja Warrior experience. Very clean with very helpful staff.

Awesome

Great place for your child to get some great exercise.

Everyone is great here! If they could my sons would be here everyday trying to bet the warp wall!

If you are lucky enough to live close to this gym or are just in town visiting as I was... attending on of trainer Dave's classes is a must! Dave has an unparalleled ability to motivate, teach, and make each activity fun while testing muscles you didn't even know you had. If it was possible to give a 10 million star review, I would!

Fun
