If you've been meaning to show your core a little more TLC, celebrity trainer Jeanette Jenkins [2] has got your back, and your abs. Instead of doing hundreds of crunches in hopes of revealing some muscle definition in your stomach, give her ab challenge [3] a try.
All you need is a medium-size stability ball [4], and you're set. This workout will target every muscle in your core from your obliques to your transverse abdominis muscles [5]. Are you ready for the challenge?
The workout:
- Ab pikes: six to 10 reps
- Ab tucks: 10 to 15 reps
- Core rotations: 10 reps
- Plank opposite leg hold: five to 10 seconds (repeat four times)
- Ball tosses: 10 to 15 reps
- Crunches on the ball (with extended arms): 15 to 25 reps
- Single-leg ab hold balance: five to 10 seconds (repeat four times)
