It's great. i used to do Pilates, Body Balance - my favourite and yoga. Haven't done them since changing gym as I loved my teachers but membership went through the roof.
Pilates is all based around your core muscles. YOu don't need to be at a certain leval of fitness to start. You take the class at your own pace and build up the movements as you get strongers. The first time I did it I felt really sick after but that never happened again. It's a fab class, very relaxing and you're working really hard and slow.
Yoga, is really relaxing and you become really flexable with it. Each week you can really see the difference in how far you come. It's also very good for the mind and I really need to get back to it. I used to do it sunday mornings which was fantastic for getting in the right mindset for the week ahead.
Body Balance is a mix of Tai Che, Pilates and Yoga and is so brilliant. You really tone up ad can feel it working but its also very relaxing too.
My favourite in order Body Balance, Yoga and then Pilates xxx
