Equipment Required
Resistance Bands
Step-by-Step Instructions
1Hold a resistance band with both hands, arms extended straight in front of you at shoulder height, palms facing down.
2Keeping your arms straight, pull the band apart by squeezing your shoulder blades together, moving your hands out to the sides.
3Hold briefly at the end position, then return with control to the starting position.
Breathing: Exhale as you pull the band apart, inhale as you return to the starting position.
Common Mistakes
Bending the elbows instead of keeping the arms straight throughout
Shrugging the shoulders during the movement
Safety Tips
Choose a band resistance that allows full, controlled range without shoulder shrugging
Contraindications — Do Not Do This Exercise If
Recent shoulder surgery, before surgeon clearance
Active rotator cuff tear with significant pain
Stop Immediately If
Sharp shoulder pain
New numbness or tingling in the hands
Progressions
Harder (Progression)
Use a stronger resistance band, or hold the end position for a longer count.
Easier (Regression)
Use a lighter resistance band, or reduce the range of the pull-apart.
Scientific Evidence
Band pull-aparts are a standard, widely-used exercise for postural shoulder health, commonly recommended in physical therapy practice for reinforcing correct scapular positioning throughout the day.³
A simple, quick exercise I recommend doing even a few times during a workday, not just as a formal exercise session. — Dr. Vishal Nigam
