starting from the hang removes the first pull, so the bar has no momentum when
the hips fire and everything comes from the extension itself
the wide grip still leans you further over than a clean-grip hang pull, so the
back holds a harder position throughout
Execution
Stand tall holding the bar at snatch width, strapped in. Hinge to lower the bar
to just above your knees. Brace your trunk and flex erectors.
hold the hang position without letting the bar drift forward
drive your hips through from a dead stop
shrug the bar as high as it will go
keep your arms straight throughout, no elbow bend
lower back to the hang under control and reset
Above the knee is preference, not doctrine. Pick a height and stay with it. If
you change it, pick Changed technique or equipment in the exercise menu.
