The one move you need for rock-hard abs
Top trainer Kelly Borowiec created a just-for-GL cardio workout that's a total fat blaster for our Feb/March '13 issue. Grab it now on newsstands for the full how-to, but for now, focus on nabbing a killer core with this one essential move we adore. Ski abs, here we come!
Step 1: Begin in plank position with your feet and hand on the ground.
Step 2: Jump your knees up toward your chest and land with both feet slightly to the left of your arms (aim for your right knee to touch your left elbow).
Step 3: Shoot your legs out into a plank position again.
Step 4: Bring your knees up toward the right side of your hands.
Aim for 19 reps per set, chicas!
