Base 13 is an extraordinary gym. You will find a small team of highly skilled coaches who know their clients well and offer both lots of challenge and lots of support. Classes are small and fun. Coaches will always make sure your form is good ensuring you stay healthy as you grow stronger. Henry has created a wonderful community, full of lovely people who will encourage you all the way along your fitness journey.

This is the gym you've been searching for your whole life! A small (but non-clique), supportive community that laugh and workout together. From my short time there, the members appear to have all become more than gym buddies but friends too, fostered by Henry and his team of mega professional, approachable, non judgmental coaches. I'm still a newbie, so I can't testify, but they also do socials and hang out together too. Oh and Henry sells branded merch too, it's not mandatory to wear the ultra cool shirts, muscle vests, and branded socks but everyone does, like they're comrades and they're proud to be part of Base13. And as for the workouts, they're all coach led, in really small groups so you're never left on your own, proper form is always their top priority and you end up learning a new 'workout' acronym or two..

Base 13 is a truly excellent gym. One of the most inclusive and friendly gym spaces I've been too! The coaches are fantastic, always ready to help and genuinely care about their clients. The community built around the gym is the real USP. There are always social events to get involved with and all of the members are super friendly. I've been a member for just over a year and wished that I had joined sooner! Everyone is welcome whether you are a regular gym goer or are just starting out. Couldn't recommend this gym enough!

This gym is an absolute gem, and the coaches are the shining stars that make it sparkle.Their knowledge turns workouts into insightful sessions, and the techniques they teach elevate your fitness game. It's not just a gym; it's a supportive community where progress is celebrated. If you're after a place that blends expertise with encouragement, look no further – this gym and its coaches are the real deal!

Can’t recommend Base 13 highly enough - great variety of training classes and a real community spirit with coaches who are personable, friendly and motivating.

Once you join Base 13 you will be hooked like I am! Results based training made fun with knowledgeable coaches that go above and beyond to help you and make you feel welcome!

I joined Base 13 18 months ago and it was a total game changer in my fitness. It’s the only gym/ workout regime I’ve ever been able to stick to consistently - the team have an incredibly friendly and personal approach to training, creating a fun and supportive environment. I used to find gyms quite overwhelming, particularly weight training. B13’s personalised approach has made a huge difference to my approach and motivation. The schedules are really flexible and the gym itself is great, and the classes are varied regularly. You also agree personal targets with your coach which makes it feel like you’re making good progress. What really sets the gym apart is the amazing community the team has built, which creates a hugely friendly and support environment.

I’ve been coming to Base 13 since the start of the year and it’s the best gym experience I’ve ever had. (I’ve tried ~lots~ of different kinds of gyms and classes in the past.) The coaches are so knowledgeable, attentive and welcoming, and they really get to know each member so they can tailor exercises to people’s needs. The classes are varied, suited to all levels and push you as hard as you want to go. They are always one of the most enjoyable parts of my day. I can’t recommend Base 13 highly enough!

This is the best gym ever! The level of care and professionalism is impressive! I've been a member of other gyms in London and none compare to Base 13. You get detailed attention to your technique, practical tips for improving the areas you are focusing on, a warm welcome and the feeling that you are part of a community. The coaches are very knowledgeable, friendly and with vast training experience. Highly recommended!

Best gym I’ve ever belonged to and I’ve belonged to many! Coaches are top notch and so knowledgeable. They do so much to make each of us feel included in the community. I moved here from the US knowing not a soul in Hither Green and I feel like I instantly gained 100+ new friends! Also love how they do quarterly fitness testing so we can see how we progress and have great apps to book classes and track progress!

Fantastic space, brilliant coaches, excellent classes and great personal training. The personal trainers are really knowledgeable and teach technique and form so well. The group classes are fun and the community is inclusive.

Base 13 is a truly wonderful and unique gym, the type I’ve always hoped to find - a great training program and a really supportive and social community. It’s a safe and inclusive place, with people of all ages and abilities. I’ve been a member for approaching two months and I’m so pleased to have joined. They offer a full timetable of classes and small group PT sessions so I have a really good balance of strength training and aerobic exercise with the accountability that I need. I’ve never felt so motivated and committed to my exercise and health. There’s also an emphasis on building a community through social events. The coaches are wonderful, they know everyone by name and offer a personalised approach according to your needs. I feel super lucky to have this on my doorstep.

An excellent gym with amazing personal trainers.

Henry and Ryan make an incredible team. Thanks for helping me get that much more in shape for my wedding!

I have always led an active lifestyle, but rarely have I seen results develop so quickly. If that weren't enough, the team is also wonderful - very encouraging and great at what they do. Highly recommend for anyone who gets easily bored at the gym.

Base 13 is the perfect place for you if you want somewhere to train, feel comfortable and meet new people. The coaches are so helpful and welcoming to all abilities. I started back in March 21 and had no idea what I was doing when it came to weight training. Now I feel comfortable lifting weights as I have been provided with the correct guidance. 100% recommend for anyone thinking about joining a gym but don't know where to start!

I can not recommend Base13 enough. The trainers are extremely knowledgable and they ensure that they take time to explain everything. There is absolutely no judgement at this gym, I am not your typical looking gym goer, but I have loved every minute of it. I have made so much progress and am much stronger than I ever imagined I could be. I love the small class sizes as that helps you be accountable rather than get lost in a larger gym class where they don’t know you. Base 13 is a community and you can be involved as little or as much as you want. I love that balance of picking and choosing. Thank you to everyone at Base 13

Been going for 3 months now and it’s honestly changed my life! I feel leaner, stronger and just healthier overall. The coaches are all wonderful. Passionate, caring, fun, and ready to push you. It’s lovely working out with a group of like-minded individuals. There is a really strong sense of community at Base 13. And I love how inclusive of an environment it is. Never any judgement, everyone just comes to work hard and have some laughs in the process! The personalised feel of the sessions and the support you get from the coaches is also something that is really special about base 13. I can’t recommend it enough.

I only intended to do a months PT, I hadn’t been in a gym for ‘several’ years, I liked working with Henry and the other coaches so much I’ve now been going for five years (and counting!). The Base 13 studio is a perfect space as a private studio and workout venue. All the equipment and space you need, with more personal focus and attention than any gym. The coaches are incredibly friendly, professional and mostly importantly fun. Thief level of experience and knowledge shows in every session. I’ve never been a ‘Gym person’ but this isn’t a gym.

If you want your gym to feel like a community then you can't get better than Base 13. Excellent trainers who are fully invested in helping you achieve your personal goals

Extremely professional and knowledgeable coaches who will work with you to help you achieve your goals. Great community spirit and lots of additional events to take part in too!

Great place , great facilities and excellent trainers

Henry has made Base13 an absolutely incredible place. Every session is personally challenging, creatively structured and nothing is left to chance. The feel of community is very strong and everyone supports one another.

Amazing class today

Base13 is one of the best things about Hither Green. Really friendly and inclusive and have met some wonderful folk through it. When I've gone regularly to sessions I've improved fitness and lost a ton of weight. The small group PT format is great as there is no slacking but also great team mentality to get you through your work out. The social events are also great fun 😁

Personalised, supportive and motivating gym for people of all fitness levels. Fantastic and welcoming community!

For the first time, I actually look forward to my workouts and never want to miss a session! Coaches are hands on and push you to achieve your goals in a positive and supportive manner. To top that, they have built a brilliant supportive and non-judgemental community with regular physical challenges and socials to keep everyone motivated whilst having a laugh. It's not easy to find a gym in London, where you feel like you belong and people genuinely care, so if you're lucky enough to have heard of Base 13 give it a shot and you won't regret.

Great fitness studio with knowledgeable, inspiring trainers, a wide range of small group training sessions and classes and a fun, welcoming community of members.

I went on a 30 day no commitment trial ar after seeing my partner really enjoyed her sessions and really improved her fitness, while keeping her enthusiasm. I’d never really enjoyed the gym, conditioning or weights before, but the supportive coaching, variety of training,, and most of all, the encouraging community Henry and his team have kept me going for two years now, in which time I’ve massively improved my fitness, lost weight and learned an awful lot- i’d definitely recommend to Base13 to anyone who wants to improve their fitness in an environment that is nonjudgmental, encouraging and fun.

Great gym, super friendly instructors and amazing group vibe. Definitely recommend for those new to working out and those looking to find a gym with a community!
