Tighter-abs workout

Side Lunge

Holding 1- to 3-pound dumbbells at your waist, stand with your feet hip-width apart. Step your right foot 15 inches to the right, bending your right knee and keeping your right hip over your right foot. While stepping to the right, reach your left arm overhead, and reach your right hand toward the floor between your legs. Return to the starting position. Repeat on the opposite side. Continue alternating for two sets of 10 to 12.
