What It Is
Pulling with one arm at a time gives you a deeper stretch. It also helps even out side-to-side differences in back strength.
How to Do It
Clip a single handle to the top pulley and kneel or sit facing it. Reach up with one arm until you feel a stretch along your side. Pull your elbow down toward your hip. Let the handle rise slowly back up. Do all reps on one side, then switch.
Skill Level
Intermediate. Free-weight lifts, single-leg balance under load, or near-bodyweight strength moves. Form matters.
Type
Strength. Builds muscle and strength with controlled, resisted movement.
Engagement
Unilateral (Non-Alternating). Do every rep on one side, then switch.
