Why we love it: The combo of ballet barre work, yoga, and Pilates uses "slow and controlled movements" to make your muscles feel it during and after, our sore testers say. Switch between lower-body focused exercises, like lunges on toes, and upper-body exercises, like mini pulses that make your triceps burn. Then finish on the floor with more butt and thigh toners. The instruction, by Sadie Lincoln -- her client Madonna is a fan -- helps this DVD feel like a private lesson. "Just when you're thinking 'Am I doing this right?' she'll give you spot-on pointers."
