If you are getting bored using the same old Pilates DVD over and over, you should check out classes at a studio near year.
It seems like Pilates studios are popping up in neighborhoods at the same rate as Starbucks coffee shops. Chances are high there is a studio close to either where you work or live. Check out this Pilates studio locator that Pilates Style has put together.
If you have never tried Pilates and are contemplating a class, I say, "Go for it!" It is a great form of exercise that makes everything better. It can help improve your running times, your posture and tone your belly!
