Now contract your torso muscles, and stretch your arms against the resistance of
the machine. Move your forearms downwards in a semicircular curve. The motion
originates from the elbow joints only and should stop when your forearms are
extended. Make sure not to hyperextend your elbow joints as this increases the
stress on your elbows. Breathe out when you exert strain against the resistance.
Maintain this position momentarily.
3.
Now bend your elbows and return the handles, making sure to maintain control.
Stop the return motion once your forearms are vertical. Breathe in during the return
sequence.
