This is strength work for Shoulder Work/Recovery Arm from my swim book - Simple Swims:practices for balanced, stable swimming
This exercise is about developing the motion and the strength in the shoulder for the recovery arm. Keep the shoulders relaxed-not to shrug them as you perform the lift.
Begin either in a standing or sitting position. Lift both arms up laterally at the side of the body until just above the head. Add weight by holding a dumbbell in each hand. You can also do this with stretch cords.
Begin either in a standing or sitting position. Lift both arms with the elbows slightly bent, lead with the elbows. This is the same motion as putting on deodorant. Add weight by holding a dumbbell in each hand. You can also do this with stretch cords.
