Exhale as you raise your body back to the starting position. Do this gently and slowly so you do not hyperextend your shoulders. Be sure to retract your shoulder blades and keep your shoulders square and stabilized (not rolled forward or up). As soon as it is difficult to hold your shoulders still and pulled back, stop the range of motion. This is 1 rep. Repeat this exercise for 2 sets of 10 reps. You should feel your tricep muscles working after 2 sets of this exercise.
