What Our Members Say
"Really great classes and friendly trainers who tailor all exercises to your needs."
a day ago"I’d been attending the run club associated with Base 13 for about a year and had heard really good things about the gym, but I wasn’t sure how I’d fit the classes into my schedule. I decided to try the 30-day trial... At first, joining a class felt quite daunting, but the coaches were incredibly friendly and quick to help... I’ve now signed up as a full member and couldn’t be happier. Highly recommend! 💪😊✨"
a week ago"Base 13 is great! All the trainers are so friendly and approachable, love that they make the effort to learn everyone's name. I was concerned with the strength training focus that I'd feel intimidated but the community is very down to earth and diverse. It's great to feel supported and encouraged to progress and achieve goals without pressure and in a fun environment."
a week ago"Base13 has become a perfect escape, the variety and amount of classes every hour is perfect for my schedule and the community Henry has built is super welcoming and inclusive, all body shapes and ages. It’s really helping my confidence on the gym floor."
a month ago"If you’re looking to join a new gym this is definitely the one for you! The team at Base 13 are incredibly welcoming, supportive and take the time to make you feel comfortable from day 1. The sessions are varied and the trainers are always there to help and push you when needed. Finally they’ve built a great community feel and make you feel welcome from your first session."
a month ago"I joined BASE 13 a month ago having never been to a gym in my life. It has been a major life changer for me and in a good way, the trainers are incredibly welcoming and supportive and tailor the classes to your ability and to take you out of your comfort zone a little at a time. I am so glad I joined and now a fully fledged member."

2 months ago"I have just finished my 30 day trial with Base 13. My schedule can vary wildly from week to week, so I was looking for a gym that offered loads of flexibility, but still class-based for external accountability. I have loved all the sessions I have done."
2 months ago"If you’re like me and haven't been to the gym in years, Base 13 is the place to go. I had never done personal training before and found the whole idea quite daunting, but the trainers here are incredible. They helped me understand exactly what I needed to do and, more importantly, helped me not hate the prospect of working out!"
2 months ago"I joined Base 13 three months ago to get fitter/stronger ahead of a ski holiday. Best decision I could have made. Training is smart, focused, and properly coached. Everything feels like it has a purpose to improve strength, mobility or fitness."

2 months ago"I used a friend’s 2 week free trial to check out Base13 and have thoroughly enjoyed my experience so far. 1 on 1 intro session, small group PT classes. Sessions run from very early to 8pm so lots of availability."
2 months ago"I’ve been going to the mum and baby postnatal sessions for over six months and can honestly say they’ve been one of the best things I’ve done this maternity leave."
3 months ago"A neighbour recommended this local, friendly, special gym, and I set a New Year resolution to join. Every part of the journey so far has been both welcoming and efficient."

COULD WE BE A GOOD FIT?
We want you to feel excited and clear before you reach out. If the list below resonates, we'd love to help you take the next step.
THIS TENDS TO WORK BEAUTIFULLY IF...
- You live near Lewisham or can get to us easily, we're a local studio and the magic happens in person.
- You've tried gyms or training alone, and staying consistent has been the hard part.
- You care about time, energy, and confidence as much as hunting for the cheapest option.
- You like the idea of being coached with a clear plan, rather than figuring it all out alone.
- You're happy to set aside regular slots in your week for 3 small, supported group sessions.
- You're open to investing in your health and see this as the start of ongoing coaching.
A DIFFERENT KIND OF PLACE MIGHT SUIT YOU BETTER IF...
- You mostly want come-and-go access without a coached programme, some prefer a traditional gym.
- The lowest possible price is always the deciding factor; coaching at this level is a real investment.
- You're only looking for a very short trial with no interest in staying on as a member.
- Fixed sessions in the diary feel impossible right now, timing matters.
REAL PEOPLE. REAL RESULTS.
"THE BEST KIND OF GYM"
"I was in the dad bod phase... I didn't want my daughter to see her dad just be a bit of a slob. Base 13 makes me feel like I want to go without forcing me to go. Think about it more as a hobby, a community, something that can bring you close to others whilst getting healthy and fit." — Machel
"FRIENDSHIPS & COMMUNITY"
"What keeps me coming back to Base 13? I think it is the friendships made here, the community that's built here. I really like the variety of the classes. You always get a lot of support from the coaches and from the people around you." — Kaz
