I’ve been a fan of Fitness First Gyms for a few years now, and I have found the Liverpool St(Shoreditch) centre to be really great. With lots of classes, cardio, weights, it’s smallish in size but contains all that you need for a comfortable workout! WIth well-stocked locker rooms, complete with hair dryers, shampoo, etc. you can leave looking better than when you arrived(which is a rare event in the Gym world!)
