Define every inch of your midsection with these targeted exercises

Trainer: Cory Gregory, bodybuilder and trainer.

Benefit: This three-move workout is designed to target and build thickness in each portion of your rectus abdominis, or your “six-pack” muscle. The weighted crunches zero in on the upper part of this muscle, toes to bar hits the lower part, and barbell rollouts hammer the entire thing.
Directions:

Perform the following exercises in the order shown.

Barbell rollout, 20 reps
Weighted crunch, 25 reps
Toes to bar, 10 to 15 reps
That’s 1 round. Do 3 to 5 rounds.
