Tricep-dip on ball
Works triceps and shoulders
(A) Sit on a sturdy chair or bench, hands on edge of the chair. Extend legs and rest calves on ball.
(B) Bend elbows to slowly lower your body about 6 to 8 inches (if you go too far, you’ll place undue stress on your shoulders), with elbows pointed back and butt close to edge of chair. Slowly return to start, squeezing your triceps at the top of the move. Do one to two sets of
8 to 10 reps, working up to three sets of 12 reps.
