The band pull-apart is a beginner horizontal abduction isolation exercise that targets the back of your shoulders. It requires only a resistance band, making it a highly practical movement for your upper body routine.
This movement heavily recruits the posterior deltoid and rhomboids as the primary drivers. Your middle trapezius acts as a supporting muscle to help control the band as you pull your arms apart and return to the starting position.
How to do it
Stand tall holding a resistance band in front of you at chest height with an overhand grip, keeping your hands about shoulder-width apart.
- Brace your core and keep your elbows slightly bent but locked in place.
- Pull the band apart by moving your hands outward and backward.
- Squeeze your shoulder blades together as the band reaches your chest.
- Pause for a brief moment in the fully contracted position.
- Slowly return your hands to the starting position under control.
Sets, reps and load
Aim for 3 to 4 sets of 12 to 20 repetitions. Higher rep ranges work well for this movement to ensure you feel the target muscles working without cheating the form.
Choose a light resistance band that allows you to complete the full range of motion without compensating with your lower back or neck.
Common mistakes
- Shrugging the shoulders. Actively pull your shoulder blades down before you start the movement. Keep your neck relaxed.
- Bending the elbows too much. Keep only a slight, fixed bend in your elbows. This ensures the posterior deltoid does the work instead of the triceps.
- Arching the lower back. Squeeze your glutes and brace your core to keep your spine neutral. Do not lean back to force the band apart.
- Rushing the eccentric phase. Control the band as your hands come back together. Do not let the band snap your arms forward.
Make it easier or harder
Easier
- Use a lighter resistance band.
- Take a wider grip on the band to reduce the starting tension.
Harder
- Use a thicker resistance band.
- Take a narrower grip to increase the tension right from the start.
