Back Flyes - With Bands
Also works: Middle Back · Triceps
A standing reverse fly against a band anchored in front of you: arms straight out at shoulder height, then swept back and out to the sides. Band tension climbs as your arms travel, which puts the hardest part of the rep exactly where the rear delt is shortest — the opposite of what a dumbbell reverse fly gives you.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Loop the band around a squat rack upright or a pole at roughly chest height and take a handle in each hand.
- Step back until the band already has light tension with your arms extended in front of you — no slack at the start.
- Set your feet shoulder-width and flat, with a slight knee bend and glutes engaged.
- Raise your arms straight out in front, parallel to the floor and perpendicular to your torso, palms facing each other.
- Pull your ribs down and brace so your torso stays put when the band tries to drag you forward.
Every rep
Breathing & tempo — Exhale as the arms sweep back and out, inhale on the return. One to two seconds out, a one-second hold at full spread, three seconds back against the band.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Use the lightest band in the rack and set the tension by how far back you step, not by which band you grab. You want a load that lets you pause for a full second with the hands behind your shoulders on rep 15. Progress by stepping further from the anchor in small increments before you move up a band thickness — bands jump in resistance far more than dumbbells do.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Lock a fixed 10-degree bend at the start and hold it. If the elbows keep collapsing, the band is too thick — swap to a lighter one and rebuild the arc with straight arms.
Cue pulling the handles apart rather than pulling them back — the traps only get involved once you start thinking 'row'. If the shoulders still climb in the last third of the arc, step 10 cm closer to the anchor so peak tension arrives with the delts still in charge.
Stand in a staggered stance with the front foot planted and squeeze your glutes. If your feet still slide, step in closer to the anchor and use a heavier band from a shorter distance.
Give the return three seconds. The stretched band wants to do the eccentric for you, and if you let it you lose half the set's work.
Why bother
The rear deltoid and mid-trapezius work hardest in the last 20 degrees of horizontal abduction — arms swept back behind the line of the torso. A dumbbell bent-over fly is almost weightless there, because the arms have reached the top of the arc. A band gets harder the further you pull, so the resistance peak and the muscle's peak line up.
The second advantage is that you are standing, not bent over. No spinal loading, no lower-back fatigue competing with the shoulders, which means you can run this at the end of a heavy deadlift day without adding to the pile. That is why it works as high-frequency corrective volume for people who press far more than they pull.
Where it fits
Anywhere in the session, honestly — it costs almost nothing to recover from. Two to three sets of 15-20 at the end of any upper-body day, or three to five days a week as a shoulder-health habit. If your bench volume is high, put this in on the same days to keep front-to-back balance.

Asked and answered
How is this different from a band pull-apart?
A pull-apart holds the band in both hands with no anchor, so tension only exists between your hands and the movement is short. Anchoring the band in front lets you use a much longer arc and get real tension from the very start of the rep. The pull-apart is the warm-up; this is the working set.
Should I feel this in my rear delts or between my shoulder blades?
Both, and the split depends on your arm angle. Straight arms swept wide biases the rear delt; letting the elbows bend and travel closer to the ribs shifts it to the rhomboids and mid-trap. Keep the arms straight if the rear delt is what you are after.
Can bands build real muscle or is this just rehab work?
For a small muscle worked in a short range, bands are genuinely competitive with dumbbells — the rear delt does not need heavy absolute load, it needs tension in the end range, which is where bands are strongest. It will not replace rows for back thickness, but for rear delts it is a real working exercise.
How often can I do these?
Three to five times a week is fine. The loads are small, the range is short, and there is no spinal or elbow cost. If you bench or press heavily, treating this like a daily habit rather than an exercise is a reasonable way to keep the shoulders balanced.
