Comments and tips
Pull with your elbows, not your biceps.
The pull-up is an important upper-body exercise, essential for building and strengthening your back and arms, and developing upper-body functional strength. Use the machine-assisted pull-up only if you can’t perform proper pull-ups. The point of the assisted pull-up machine is to help you to build enough strength to be able to do pull-ups unassisted. All you have to do is keep reducing the amount of assistance provided by the machine.
Some assisted pull-up machines are different from the one in the illustration in that instead of kneeling on a pad, you stand on a bar. See video.
