I do the "Pick Your Spot" pilates tapes. There are 3 ten-minute sessions.....one for abs, one for thighs, one for the butt. Depending on how you feel on any given day, you can do 1, 2 or all 3 sessions. 10 minutes or 30 minutes....it's up to you. I like Pilates because it's "no impact" and the stretching makes me feel really good.
