I was only in Brixton for a month and was recommended Gymnasium for their training and community. It didn’t disappoint. The coaches are ace and so welcoming – no egos were present and it was exactly what I needed. The gym is super clean and is a massive step up from the usual CrossFit railway arches. I saw my training improve and had a real laugh along the way. I’ll be coming back to drop in when I’m visiting Brixton. Thank you Nic and the team. X

I’ve been a member at Gymnasium for just under a year and have loved every moment. Varied classes, friendly and professional coaches and a vibrant community. I have particularly enjoyed the exceptionally well organised events which occur throughout the year.
