I love pilates! I've been going roughly 2-3 times a week since about March, and I've noticed dramatic improvements - especially in my yoga practice. I first started to notice the strength and endurance benefits, both in my yoga practice and in my day to day activities, but it wasn't long before I started to notice changes in my physical appearance as well.
In the past, pilates has frustrated me. I used to always feel uncoordinated while trying to do the exercises. I had a DVD that I would do just on occassion, so I never got to see results - I'd feel the burning in my muscles the next day and that was about it. Since attending a class though, I've been so motivated by my instructors and the other people around me that I actually enjoy it quite a bit. And it's such a versitile form of exercise that can be practiced in so many ways, I've never been bored with it. Usually, quite the opposite - I'm usually excited to go and experience all the changes in my body's strength and try new ways to challenge myself.
I can't say enough about it. I can do not only headstands in yoga now, but I can do headstand splits. I directly attribute that to my increased core strength!
Right on girl!
