Band Pull-Apart

A band exercise where you pull a band apart from arm's length to your chest. It trains the rear delts and upper back with almost no setup or recovery cost. Good as a warm-up before pressing or as high-rep accessory work for anyone.

Muscles worked

The rear delts pull the arms horizontally backward, while the rhomboids and mid traps draw the shoulder blades together at the end. An overhand grip leans more on the rear delts; an underhand grip brings in a bit more of the mid back.

How to set up

  1. Hold a light band with an overhand grip, hands about shoulder width apart.
  2. Raise your arms straight in front of you to shoulder height.
  3. Keep a slight bend in the elbows.
  4. Stand tall with your ribs down and abs lightly braced.

How to do each rep

  1. Pull the band apart by moving your hands out to the sides until it touches your chest.
  2. Keep your arms at shoulder height as you pull.
  3. Pause for a second with the shoulder blades squeezed together.
  4. Return slowly, keeping tension on the band all the way back.

Common band pull-apart mistakes

Shrugging the shoulders up

Keep the shoulders down away from the ears and use a lighter band if they creep up.

Bending the elbows into a row

Keep the arms nearly straight so the rear delts move the load.

Arching the lower back

Brace your abs and keep your ribs stacked over your hips.

Sets, reps, and progression

Surpass starts the band pull-apart at 12–20 reps with about 2 reps in reserve. As an isolation exercise it fits well after your main compound lifts.

Start with 15-25 reps per set. Progress with a narrower grip, a stronger band, a pause at the end, or more total reps across the week.

Know what to lift next time

Surpass shows what you lifted last time beside a target for this set, and adjusts it from your reps and RIR. Free on iPhone, no account needed.

Band Pull-Apart alternatives

These train the same main muscles. Swap when the equipment is busy, something hurts, or progress has stalled for several weeks.

Questions

Are band pull-aparts good for posture?

They strengthen the rear delts and upper back, which helps balance a lot of pressing. They will not fix posture on their own, but they are a cheap way to keep the back of the shoulders in proportion.

How often can you do band pull-aparts?

Because the load is light and they cause little soreness, many lifters do a few sets most days or before every upper-body session. Cut back if your shoulders feel irritated.
