Flat Stomach, Tight Buttock

Alternate-Leg Dead Lift

Hold a 5- to 15-pound dumbbell in each hand and stand on your right leg, lifting your left leg a few inches behind you (a). Keeping your back straight, lean forward from your hips until your body is almost parallel to the floor, the weights in line with your shoulders (b). Return to start. That’s 1 rep. Do 12, then switch legs.
