I just got Winsor Pilates a couple weeks ago and I really like it. I've taken some pilates at the gym but this is a good, easy way to do it at home. I think the instruction on positioning is good and they always have a 'modifier' who is doing the exercises for people who have less flexibility or weak backs, things like that. The exercises are easy to do and you can really feel them afterwards. I'd recommend them, but really I'd say just do anything that you can stick to. Exercise works best with consistency.
