Body part: Shoulders · Muscle group: Rear deltoid · Equipment: high pulley, seated
Why this exercise
Rear delt isolation with cable tension from a high angle. Seated position prevents body sway. The 12:1 lever ratio on the rear deltoid means moderate cable weights create substantial internal tension.
12:1 rear delt lever — the insertion point is close to the shoulder joint; the pull angle from the high cable maximizes perpendicular force.
Seated stability — prevents the swaying and trap shrugging that plague standing rear delt work.
Tension continuity 18/20 — high cable maintains tension through the full arc of shoulder horizontal abduction.
Placed second to hit all three deltoid heads while the shoulder complex is fresh.
