I love winsor pilates, after 3 kids it has really helped get my "core" back together. It was really tough at first, but I'm now amazed at what I am able to do. I've never been so flexible in my life. Still have some weight to lose, but I've never been stronger. I love to do it on off days when I'm not really up for a real intense workout.
Right now you can get the basic set for $9.95 which is a steal.
