Dumbbell reach crunch
Lie back on a mat with legs extended toward the ceiling, perpendicular over hips. Hold one dumbbell with both hands, and reach up toward your left toes, lifting shoulders as high as you can while curling torso off the floor. Hold for two counts, then return to starting position. Reach up to right toes, hold, come down, and continue alternating side-to-side reaches 18 to 24 reps per side.
