I have been doing the Pilates and Abs Class in Balham for two months now - and before that I did the Zumba Classes. It is the same instructor for both classes and she is amazing, fun and full of energy. I really enjoy her classes and come out feeling that I have had a great work out! The only negative thing I have to say is that - the instructor plays the music a bit too loud and I can't always hear what she says it you are at the back of the class apart from that Go Mammoth is a great club to belong to and the staff are all very helpful.
