Celebrity Shape-Up

ROLE Superheroine Silk Spectre II (Laurie Jupiter) in Watchmen
WORKOUT ROUTINE To prep for her first action movie, Malin Akerman paired up with former Navy Seal Logan Hood. The already slender actress "didn't need to make any drastic changes," Hood says. "She did a lot of her own action scenes so we focused on movement, strength and general stamina." Hood helped Akerman increase her endurance and strength with rowing, running and weight lifting.
TRY IT Get your whole body working with one of Hood's circuits: Pace off a distance of 25 feet. Perform 10 squats, then do a walking lunge for 25 feet. Follow up with nine push-ups and lunge back. Then do eight squats, lunge, and follow with seven push-ups. Continue until you reach one push-up.
HER EQUIPMENT
4-7 pound D-ball, D-Ball, $55; d-ball.com.
"To make the circuit more of a challenge you can carry a d-ball with you or overhead," says Hood.
