Resistance Band Pull Apart (Supination At 90 Degrees)
Resistance Band Pull Apart (Supination At 90 Degrees) Exercise Description
The Resistance Band Pullapart (Supination at 90 Degrees) is a horizontal shoulder abduction drill performed with the arms at shoulder height (approximately 90° of shoulder flexion) and a palms‑up grip. The supinated grip promotes humeral external rotation while you retract and slightly depress the scapulae, emphasizing the posterior deltoids, middle and lower trapezius, and rhomboids, with the rotator cuff (infraspinatus and teres minor) contributing to stabilization. This variation reinforces clean shoulder positioning for pulling patterns by training controlled scapular motion and upper‑back engagement. Keeping a neutral spine, level shoulders, and steady ribcage prevents compensations like lumbar extension or shrugging. Use a band resistance that allows full range with smooth control and consistent wrist‑neutral alignment.

How To Do The Resistance Band Pull Apart (Supination At 90 Degrees) Exercise
‘- Stand tall, feet hip‑ to shoulder‑width, spine neutral, ribs stacked over pelvis.
– Hold a light band at shoulder height with a palms‑up (supinated) grip.
– Hands start about shoulder‑width; choose spacing that allows full, controlled range.
– Set shoulders: gently draw shoulder blades down and back; keep neck long.
– Keep elbows straight but not locked; wrists neutral and aligned with forearms.
– Inhale to prepare; brace lightly without flaring the ribcage.
– Exhale as you pull the band apart, moving arms into horizontal abduction.
– Maintain palms‑up and shoulder height; avoid shrugging or arching the low back.
– Finish when upper arms align with shoulders and scapulae are retracted and slightly depressed.
– Pause briefly with control; feel tension across the upper back, not the wrists.
– Inhale as you return the band to the start under control; do not let it snap.
– Keep head neutral (chin tucked slightly) and repeat only with the same precise form.
Resistance Band Pull Apart (Supination At 90 Degrees) Tips
‘- Stand tall with spine neutral and ribs stacked directly over the pelvis to avoid compensations.
– Hold the band at shoulder height with a palms-up grip to promote humeral external rotation.
– Start with hands about shoulder-width and adjust spacing so you can move through a full, controlled range.
– Gently draw the shoulder blades down and back before you start to set the scapulae.
– Keep elbows straight but not locked and wrists neutral in line with the forearms.
– Maintain level shoulders and a steady ribcage; avoid shrugging or arching the lower back.
– Exhale as you pull the band apart into horizontal abduction, keeping the arms at shoulder height.
– Stop the pull when the upper arms align with the shoulders and the scapulae are retracted and slightly depressed.
– Pause briefly at the end of the range and focus on tension across the upper back rather than in the wrists.
– Inhale as you return to the start position under control, not allowing the band to snap, and repeat only with the same precise form.
Resistance Band Pull Apart (Supination At 90 Degrees) Beginner Introduction
The Resistance Band Pullapart (Supination at 90 Degrees) is a standing band exercise that targets the rear shoulders and upper back while the arms move outward at shoulder level. With the arms lifted roughly to a right angle in front of the body and the palms turned upward on the band, the upper arms naturally rotate outward, placing more emphasis on the back of the shoulders, traps, upper back, and the smaller stabilizers around the shoulder joint.
This drill highlights smooth, deliberate motion of the shoulder blades and steady engagement across the back rather than relying on momentum. A tall, balanced stance with a calm midsection supports the movement so the lower back and neck stay relaxed instead of compensating. Elbows remain straight but relaxed, and the wrists line up with the forearms for comfortable band tension. A band that allows a complete, unhurried pull and return helps reinforce precise shoulder mechanics that carry over to rowing and other pulling patterns.
