Liam has been a long standing member at gymnasium and we have loved seeing his progression over the years. Recently, he’s joined a rowing club taking his technique to another level which is awesome!

You’ll find him at the gym most days, even with an injury he works around it and scales back during workouts. Work smarter not harder !

Congrats, Liam - and thanks for sharing your good vibes with us 💛

I love this place! Been coming for a few weeks now and can’t wait to get going each day! It’s a hard workout, but the coaches and community are great!

I joined Gymnasium after a friend recommended it to me and boy am I glad I did. Literally the best decision I’ve made for my health and fitness. Great value for money if you go regularly. The coaches are fantastic, I’ve learned so much in such a short space of time. The facilities are great too and it’s refreshing to be part of a gym that everyone looks after and the community spirit here is what breathes life into the place. I love it!

We absolutely loved Gymnasium! It is has been a challenge to find a gym/box that comes close to ours back home in Australia, but Gymnasium made us feel like home. The coaches were brilliant and the other members were so nice and welcoming.The equipment is all in excellent condition and the facilities are top notch. Would absolutely recommend to anyone who is looking for a great gym or CrossFit box.

Gymnasium and crossfit have literally changed my life. I finally found something I love doing and always look forward to. The diversity of the classes and the possibility to also do your own thing in open gym makes it the perfect place to go to.Since I started I've become much stronger, faster, fitter, leaner but also happier in my body!The coaches there are incredibly knowledgeable, help you become better/stronger, but also care about your progression and make sure you exercise safely. They're also friendly and always genuinely make you feel welcome and part of the community which, let's be honest, is not something you find in your normal gym.The community and social aspect are pretty awesome too, I've only joined 8 months ago but feel part of the family and have made some really good friends there.If you want your face on a billboard at Clapham North, make cool friends, get fitter, stronger and happier, this is the place! 🙂
