The Strap-Happy Shaper exercise works your shoulders, upper and middle back and abs.
This next exercise is going to sculpt your shoulders and your upper middle back. Let's come forward into a plank position. Okay, hold your arms, elbows underneath the shoulders, and then lift the legs up. Tuck your toes under. Lift your abs and then take your chest forward, and back. Forward, exhale, back. Eight to ten times, exhale back, and you'll feel it.
