Jeanette Jenkins' Ab Challenge

Sculpt a 6-Pack With This Celebrity Trainer's Ab Challenge

If you've been meaning to show your core a little more TLC, celebrity trainer Jeanette Jenkins 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 a try.

All you need is a medium-size stability ball, and you're set. This workout will target every muscle in your core from your obliques to your transverse abdominis muscles. Are you ready for the challenge?

The workout:

  1. Ab pikes: six to 10 reps
  2. Ab tucks: 10 to 15 reps
  3. Core rotations: 10 reps
  4. Plank opposite leg hold: five to 10 seconds (repeat four times)
  5. Ball tosses: 10 to 15 reps
  6. Crunches on the ball (with extended arms): 15 to 25 reps
  7. Single-leg ab hold balance: five to 10 seconds (repeat four times)

Watch the full video above to see how each move is performed, and complete two to three sets total.
