At-Home Fitness: 10 Easy Ab Moves For A Bikini Body Before Summer Ends

Start with a 4 to 6 pound ball and remember to mind your back. Step 1: Lay on your back with your legs off of the ground and the ball in your hands above your head. Step 2: Bring your legs up to your waist and place ball between ankles. Step 3: Clenching legs, return to beginning position with ball between ankles. Repeat 3 sets of 10! Tip: The slower you lower your legs in step 3, the more you are working your abs! [Photo via]
