Band pull-apart

Holding a band at arm's length and pulling it apart — the simplest upper-back movement there is, and the one bands are best at.

What to watch

  1. Arms stay straight throughout
  2. Lead with the hands, not the chin
  3. Return under control, do not snap

What it is

Hold a light resistance band in both hands, arms straight out in front of you at about chest height, hands roughly shoulder width or a little wider.

Keeping your arms straight, pull your hands apart until the band touches your chest and your arms are out to the sides. Let them return under control.

Hand spacing is the dial. Narrower is harder; wider is easier.

What it demands

Very little strength and quite a lot of endurance. This is a high-repetition movement by nature, and the band's resistance is small compared with anything you would row.

Scapular retraction — drawing the shoulder blades together — from the rhomboids and middle trapezius, with the rear deltoid pulling the arm back.

The demand it makes that weights do not: a band is hardest where it is most stretched, which here is at the very end of the movement, where your shoulder blades are already fully drawn together. A dumbbell gets easier there. That reversal is the genuine mechanical difference between band and free-weight training, and it is neither better nor worse — it is different.

What usually goes wrong

Bending the elbows. As it gets hard the elbows bend and it becomes a row. Straight arms throughout, or it is a different exercise.

Letting the band snap back. The return is half the work, and a band under tension returning fast is also the way people catch themselves in the face.

Shrugging. Shoulders stay down; the movement is horizontal.

Choosing a band that is far too strong. Very common. This should be light enough to do many clean repetitions.

Where it sits

The entry point to horizontal pulling and the movement bands are genuinely best at — light, high-repetition, portable, and needing nothing to anchor to.

It leads to the band row, which anchors the band and lets you use much more resistance. The face pull is its close neighbour, working the same region with the arms higher and some external rotation added.
