Pull up

You are generating significant momentum through your lower body to reach the top of the bar.

What the coach saw

At the start of the pull, your knees drive forward and upward to help propel your chest toward the bar. While this allows you to clear the bar at the top, it shifts the focus away from the back musculature. You maintain a strong grip throughout the movement, but the swinging motion becomes more pronounced as you descend back to the bottom.

Try this next set

Try to keep your legs straight and squeezed together to ensure the upper back and arms are doing all the work.
