SHOULDER ABDUCTION 4000
1.
Adopt the right exercise position: Sit on the seat with your upper body upright. The
shoulder joint should be at the same height as the rotation axis of the exercise
machine. Place your feet about shoulder width apart. Grasp the handlebars with
your hands. Your palms are facing each other. Bend your elbows at a right angle.
Your forearms touch the inside of the arm pads (also see Chapter 5.4).
2.
Now contract your torso muscles, extend your arms sideways and upwards against
the resistance of the machine until your arms reach the height of your shoulders.
The motion originates from the shoulder joint only. Breathe out when you exert
strain against the resistance. Maintain this position momentarily.
3.
Now return your arms, making sure to maintain control. Stop the return motion
shortly before reaching the torso. Breathe in during the return sequence.
