...is not exactly a pull-up.
It is actually the front lever-row.
This movement is sometimes referred to as a front lever pull-up, but I think a row is more descriptive to what it actually is. Here's why:
The front lever ROW, although it is done from hanging, involves pulling in the horizontal plane (a row). A pull-up is done in the vertical plane.
But I digress.
Prerequisite: Tuck Lever for 10 seconds
Execution: Beginning in a front lever variation you can comfortably hold for 10 seconds, pull the elbows toward the hips and the hands to the bottom of the ribcage. Note, it will be difficult to get FULL ROM but at least look for 90+ degrees of elbow flexion. Emphasize keeping the shoulders down toward the hips (opposite of shrugging) and focus on engaging the lats.
Mix in front lever rows anytime that you would normally do pull-ups, rows, or even front levers. This movement can hit them all!
