L seat hold

This is one of the best static moves to learn - on any bar - as it helps with so many other moves. Starting from the top position of a dip, keep your body still whilst raising your legs to 90 degrees and then hold them in place. There are progressions to this move if you’re unable to perform it.

There’s a short video demonstrating this exercise on this page. For more resources to help your calisthenics journey, check out courses here.
