Query: A Tough Workout

I love Pilates and Yoga, and this combines the best of both. Jennifer Kries is terrific. She's warm, and friendly and explains the moves and positioning of your body without talking down to you. The video video is 40 minutes, with 15 minutes of upper body sculpting and 15 minutes of lower or "total" sculpting for the legs, buttocks, and thighs. Some of the moves are hard, especially towards the end. There are some variations on push-ups that if you have little or no strength in your arms I would either skip or do less of them until you gain the strength. When paired together with The Method's Precision Toning you have the perfect 1,2 punch to your workout regime.
