Six Moves to a Six-Pack
KETTLEBELL PULLOVER HOW TO DO IT: Lie on your back and raise your legs. Bend your knees 90 degrees and spread them apart while keeping the bottoms of your feet together. Lift a kettlebell straight above your head, holding the sides of the handle in both hands. Lower the weight behind you, stopping a foot off the floor. Hold for 30 seconds, and lift it back above your head. That's 1 rep. Do 5.
