August's Top Workout DVD: Mandy Ingber's Yogalosophy
Best for: Reluctant yogis seeking an extra strength challenge; those who want to train like a Hollywood star.
Why it's a star: Mandy Ingber, a 15-year fitness veteran and trainer to Jennifer Aniston (your celebrity body role model), banishes yoga boredom by integrating strength and balance moves with traditional poses. (For example, you'll hold a crescent pose as Mandy is doing on the cover, then do two sets of lunges.) The 55-minute routine is not for yoga purists, but by the time you reach the relaxing stretch at the end, the workout will feel well worth it.
Where to get it: amazon.com, $10.99
