Third Space Chelsea - (Near Kensington and Chelsea, UK)

Quietly Rated A solid gym with a recent renovation that brought in more equipment and upgraded its offering. The space is large and rarely overcrowded, even during peak times. Equipment is mainly from Technogym and generally in good condition. There’s a pool, sauna, and muscle recovery zone, as well as decently sized changing rooms. Classes are on offer, and while not exceptional, they’re fine for regulars. Staff is friendly and the vibe is clean and professional, though the music can be unnecessarily loud. Main downside: the price tag. It’s starting to feel steep for what’s on offer. Quietly rated: worth joining – unless the prices go up.

Snss106 S I initially visited the gym last weekend and met Alex who explained the set up and offered to show me how to use certain machines at my next visit. I returned today and as expected, he very kindly showed me how to use all of the machines and even took the time to give me a list of which exercises to do. I am not new to fitness but have generally found gyms to be a bit intimidating and centre my workouts around outdoor activities. A big shout out to lovely Alex who took the time to help me out today - its people like you who encourage more women to strength train!

Renee Wood-Gush I absolutely love 1Rebel Chelsea! The new studio is gorgeous – modern, spacious, and such a motivating environment to work out in. The staff are amazing – so friendly, welcoming, and always on hand to help. Every class feels so energising and the team really make you feel part of the community. Couldn’t recommend it more if you’re looking for a fun, high-energy workout in a stunning new space!

Aaliyah Da Silva What a lovely environment to be in! The team are all so joyful and attentive to whatever your needs may be. Highly recommended doing the Reformer Pilates even as a beginner! I also want to shout out Erica who was incredibly helpful & made me the most delicious protein shake. Will definitely be coming back.

Desislava Shaumyan All three of my children trained with Stefan Kolimechkov and I can say that he is one of the best and most professional people I know. If someone wants to practice gymnastics, Chelsea Gymnastics Academy would be their best decision.

Alicia Sanchez Tomas Ive been going to Six Physio for two years now (before and after my hip replacement in September 2025). And my coach, Lizzy Parry, has been with me the whole time. Ive never met a more responsive, supportive, and patient professional! Working with Lizzie twice a week allowed me to get by without crutches for the first 6-8 weeks after surgery, for which Im very grateful. I am continuing my sessions at Six Physio and am starting to enjoy long walks again. I highly recommend Lizzy and her sessions.
