How to perform
Attach a rope or bar to a high pulley and take a grip at chest height.
Tuck your elbows to your sides and keep them there for the entire set.
Extend your arms down until they are straight, spreading the rope at the bottom if using one.
Return under control until your forearms are just past parallel.
Common mistakes: letting the elbows drift forwards and backwards, and leaning over the weight to press it down with bodyweight.
