Flat Belly Fast—No Crunches! Four moves that guarantee you'll get abs in six weeks

Reverse Wood Chop

Squat, holding a medicine ball next to your right hip (a). Keep your arms straight and raise the ball up and across your body until you're standing and the ball is above your left shoulder (b). Lower back to start. That's one rep.

 

Single-arm Lunge

Hold a dumbbell and raise your right arm, keeping your elbow close to your ear (a). Step forward with your left foot, lowering until your thigh is parallel to the floor (b). Push off your left foot to stand. That's one rep.
 

T-Stabilizer

Get into a pushup position (a). Shift your weight to your left hand and rotate your body, raising your right arm into the air so that your arms and torso form a T (b). Hold for one or two seconds, then return to start. That's one rep.
 

Single-arm Bent-over Row

Hold a dumbbell in your right hand, bend your knees, and lean forward from your hips (a). Brace your abs and pull the weight up to chest height without rotating your torso (b). Return to start. That's one rep.
