Sculpt Bolder Shoulders

Strong, stable shoulders will help you lift more weight in nearly every upper-body exercise. So start each upper-body workout with the band pull-apart, suggests Shon Grosse, P.T., C.S.C.S., owner of Comprehensive Physical Therapy and Fitness in Colmar, Pennsylvania. It trains your rotator cuff and scapular stabilizers, the network of muscles that help create a strong shoulder joint. (And it counts as another pulling exercise.)

Keeping your arms straight, use both hands (palms up) to hold a stretch band out in front of your chest. Now squeeze your shoulder blades together and stretch the band out to your sides, without bending or lowering your arms, until the band touches your sternum. Reverse the move and repeat. Do 2 or 3 sets of 10 to 15 reps, resting 60 seconds between sets.
