While the Clean is executed from the ground, the Hang Clean, demonstrated here by CrossFit Seminar Staff member James Hobart, is a variation of the movement, which is started from a ‘hanging’ position i.e. above ground level in any of the following start points:
High-Hang: Upper thigh
Hang: Top of knee caps
Knee: Bar at knee caps
Low: Bar just below knees
If nothing is specified, the Hang Clean is typically done from just above the knee and this is the point that everybody should work from in the initial months of learning and developing the Clean. More experienced athletes work the hang positions as a training exercise to produce more explosive force in the hip extension.
