Look no further than Michaels's Shape-Up Backside exercise DVD for an intense high-impact workout. Michaels keeps your body moving with hammer curls, oblique raises, step ups, planks, and a move called The Superman destined to tone your back, biceps glutes, hamstrings and abs. There's a lower-level option, but Michaels likes to "kick your butt," as she says, to get you to feel the burn.
