Can you explain how it works? Is it something I can do with improvised equipmemt in the gym?
EDIT: maybe i got it, i could put the smith machine bar at shoulder level, place the bar pad on it, tie one end of a rope to the pad and weight to the other end of the rope. Then I’d roll the shoulder pad to drag upwards the weighted rope, and roll it to the other side to let the rope drop back, correct?
