Although this move targets your abs, squeezing a ball between your legs also works your inner thighs. Here's a video demonstrating this effective move.
- Lie on your back, holding the ball with straight arms lifted toward the ceiling; raise your legs toward the ceiling too.
- Keep your lower back pressed into the floor as you lower the ball above your head and your legs toward the floor.
- Return to starting position, and switch the ball so you're holding it between your feet.
- Lower your feet to the floor, reaching your arms overhead. Return to starting position.
- This counts as one rep. Complete two sets of 10 reps.
