If you take Pilates, how many times a week do you go? Is it the only form of exercise you do, does it give you a full body workout? I'm planning on signing up for 2 days a week (1 hour each class). I've taken it before, but it was only offered one day a week (at the Y) and I know that wasn't enough. Now they offer two days, so I thought that could work. I'm just wondering what else I'm going to need to add to my workout (spinning, weights etc).
