Starting position

Reverse grip lat pulldown

Grab the bar on the pulldown machine with your palms facing you and with a closer than the shoulder width.grip. Extend your arms and lean back creating a curvature on the lower back. That is the starting position. Now, as you exhale, pull down until the bar touches your upper chest.
Now, as you inhale, bring the bar up extending your hands and getting back to the starting position. That is one repetition.





IMPORTANT: throughout the movement of this exercise your forearms should only be used for holding the bar. DO NOT USE THEM TO PULL DOWN THE BAR.
