The Thigh Resizer
Pure Barre Studio Series ($60 for two DVDs, a towel and socks;purebarre.com)
Best for: Barre-workout devotees looking for a faster-paced workout.
What it is: A 45-minute ballet-meets-Pilates session, created and led by Pure Barre founder Carrie Rezabek Dorr. Exercises place a heavy focus on your lower half, working it to the point of fatigue; you then follow up with stretching.
Testers' take: Although it flew by, this routine felt like a substantial workout. One reviewer confessed, "Even though I take barre regularly, this DVD was challenging, especially the ab section."
