Her workout: Power yoga with Los Angeles yoga guru Mark Blanchard.

Check out: Mark Blanchard's Progressive Power Yoga, a collection of three sweat-inducing, 90-minute routines on video or DVD. Blanchard recognizes that doing a single workout repeatedly is not only boring but also inefficient, since your body adapts to it and ultimately ceases to progress. So, he recommends doing each routine once a week to keep your workouts feeling fresh and challenging.
