Lie on your back with a three- to five-pound dumbbell in each hand. Raise your arms straight up above your chest, with a slight bend at each elbow. Raise your legs up to tabletop, with knees and hips bent to 90-degree angles.
Inhale and open your arms to your side, with a slight bend at each elbow. Exhale as you bring your arms back up to starting position.
Lift your upper back and curl up toward your legs, pushing your weights toward your shins. As you curl up, stretch your legs out in front of you.
