Brooke Burke-Charvet's One-Minute Workout

Dancing with the Stars

co-host Brooke Burke-Charvet has a few favorite moves from her latest Brooke Burke Body DVDs, 30-Day Slim Down and Sexy Abs. These three exercises will tone your abs, legs, and butt—and they're so quick you can knock them out during a DWTS commercial break.

"Do each in 30-second to 1-minute 'pods,'" Burke-Charvet advises. "Tackling a whole minute is hard every time. And when you get that burn, do 10 more seconds. That's when your body starts changing."

Lie with knees bent, arms at side, palms down. Tighten glutes and core; raise hips to form a straight line from shoulders to knees (A). Bend right leg toward chest (B); straighten leg and point foot (C); bend leg and return to start. Repeat, alternating sides, for 1 minute.

Kneel, place left hand lightly on back of head, right hand on floor to side. Lift left leg 2 inches off floor (A). Crunch to left while raising left leg, so body forms a straight line from hip to toe (B). Lower leg and repeat for 1 minute; switch sides and repeat.
