Use yoga-inspired exercises to sculpt and tone your abs, legs, arms and butt in this comprehensive workout from the provocatively named Skinny Bitch series. Each 20-minute section targets a different body part. Toning and resistance exercises are designed to firm up the arms, tighten the tush, slim down the legs and flatten the stomach. The program is based on the tough-love fitness best-seller by Rory Freedman and Kim Barnouin.
