How to set it up

1
Set the seat so the elbows or hands align around chest height.
2
Keep the back and head supported throughout the movement.
3
Choose a starting arm position that does not pull the shoulders uncomfortably backward.

How the movement works

1
Bring the arms together in front of the chest along the machine's curved path.
2
Open the arms slowly until the chest is comfortably lengthened, without forcing the shoulders back.
