The resistance band assisted single arm pull-up is an advanced back and biceps exercise that uses a looped resistance band to reduce the load and help you build toward an unassisted single arm pull-up. It targets the latissimus dorsi, biceps, rear deltoid, and core, demanding significant unilateral strength and stability. The band assistance scales down as you get stronger, making it an effective progression tool for one of the most challenging bodyweight pulling movements.

Cómo hacer el Resistance Band Assisted Single Arm Pull-up

  1. 1Loop a resistance band over the pull-up bar and let it hang down. Choose a band thickness that gives enough assistance to complete the target reps with control.
  2. 2Place one foot or knee into the hanging loop of the band to support your body weight.
  3. 3Reach up and grip the bar with one hand, palm facing away or toward you depending on your preference, with your arm fully extended.
  4. 4Engage your core, depress your shoulder blade, and brace your torso to prevent twisting.
  5. 5Pull your elbow down and back toward your hip, driving your chest up toward the bar.
  6. 6Continue pulling until your chin clears the bar or your chest approaches it, keeping your body as vertical and controlled as possible.
  7. 7Lower yourself slowly back to a dead hang under control, resisting the urge to drop quickly.
  8. 8Complete all reps on one arm, then switch to the other arm and repeat.

Consejos de técnica

  • Use the minimum band assistance needed to complete each set with good form — using too thick a band limits the strength gains you are after.
  • Focus on initiating the pull with your lat by depressing and retracting the shoulder blade before bending the elbow.
  • Keep your free hand off your body or rested lightly on your wrist — not gripping the working arm — to avoid cheating the movement.
  • Squeeze the bar hard with your working hand; a stronger grip creates full-body tension that makes the pull easier.
  • Progress by switching to a thinner band over time rather than jumping straight to the unassisted version.

Errores comunes

  • Twisting the torso toward the working arm, which shifts the load away from the target muscles and stresses the shoulder joint unevenly.
  • Using a band that is too thick, which can mask weakness and slow progression toward the unassisted single arm pull-up.
  • Dropping too quickly on the way down, which skips the eccentric phase where significant strength is built.
  • Letting the shoulder shrug up toward the ear at the start instead of depressing it first, reducing lat engagement and stressing the rotator cuff.
  • Gripping the working wrist with the free hand, which secretly converts the movement into a two-arm pull-up and removes the unilateral training stimulus.

Preguntas frecuentes

What muscles does the resistance band assisted single arm pull-up work?

It primarily works the latissimus dorsi (the broad back muscle), with strong contributions from the biceps, rear deltoid, and core, which must resist rotation throughout the movement.

How do I progress toward an unassisted single arm pull-up?

Start with a thick band and work up to sets of 5–8 controlled reps, then gradually switch to thinner bands over several weeks. Adding slow negatives — lowering yourself with one arm from the top position — also builds the necessary strength quickly.

Which band should I use for a single arm pull-up?

Start with a band that lets you complete 4–6 clean reps. For most people that is a medium or heavy band (roughly 50–80 lb assistance). Move to a lighter band once you can hit 8 reps with full control.

Should I use a supinated or pronated grip for a single arm pull-up?

Either works, but a supinated (underhand) grip typically allows a slightly stronger pull and involves the biceps more, making it a common starting point. A pronated (overhand) grip is harder and is the standard competition form.

How often should I train the single arm pull-up?

Two to three sessions per week with at least 48 hours of rest between sessions is effective. The movement is neurally demanding, so quality reps matter more than volume — keep total reps low and focus on crisp, controlled technique.
