I've tried lots of different gyms and fitness classes over the years, including the likes of Barry's Bootcamp and Soul Cycle, and none of them make me feel quite as much like an athlete as Altitude does. The team there actually care about your performance and listen to your goals, instead of trying to push the next fitness fad onto you. Not only that, their concept is focused on high altitude training through their spacious and well-equipped altitude chamber, which is a very effective way to improve your fitness. I love their classes, which really push you and manage to be fun and energizing at the same time. I would recommend Altitude to anyone regardless of fitness-level, who are looking to improve their overall health and join an encouraging community - even better if you're training for an event or signing up for a climb.
