Formula: Abs Three Ways
Moves provided by Michele Olson, PhD, professor of exercise science at Auburn University at Montgomery and creator of the Perfect Legs, Glutes & Abs DVD.

Do three-move mini circuits: Match a faceup ab exercise (your fave, whether it’s bicycles or the Teaser — we know you have one) with either a facedown or side-lying move (like the Loaded Hip Dip) and a standing one (try the Upright Supercrunch).

Upright Supercrunch

Targets lats, abs, and obliques

Stand with feet hip-width apart, holding a 4- to 6-pound medicine ball overhead; lift right leg slightly behind you.
Engaging abs, hinge at waist to do a crunch as you bring right knee up toward chest and lower ball diagonally toward right hip.
Return to start. Do 10 reps. Switch sides and repeat.
