Band Overhead Single Arm Triceps Extension

  • Beginner
  • Isolation

  • Shoulders

This unilateral isolation exercise targets the long head of the triceps by placing the muscle in a fully stretched position. Using a resistance band provides ascending tension, maximizing the contraction at the top of the movement while improving elbow health.

Muscles worked

Primary

  • Triceps

Secondary

  • Deltoids
  • Forearms

Equipment

  • Resistance band

Setup

  1. Anchor a resistance band to a low point on a power rack or sturdy post.
  2. Stand facing away from the anchor point in a staggered stance (one foot forward) for better balance.
  3. Grasp the band with one hand and bring your arm up so your elbow points toward the ceiling and your hand is behind your head.
  4. Engage your core and tuck your ribcage down to prevent your lower back from arching.

How to do it

  1. Exhale and extend your arm vertically by straightening the elbow until your hand is directly over your shoulder.
  2. Squeeze the triceps hard at the peak of the movement, ensuring the upper arm remains stationary.
  3. Inhale and slowly lower the band back to the starting position behind your head, maintaining tension throughout the descent.
  4. Perform the movement with a controlled 2-1-2 tempo (2 seconds up, 1 second squeeze, 2 seconds down).

Form checklist

  • Keep your working elbow tucked close to your ear; avoid letting it flare out to the side.
  • Maintain a vertical upper arm position throughout the entire set.
  • Keep your head neutral and chest up; do not let the band pull your neck forward.
  • Ensure the movement only occurs at the elbow joint, not the shoulder.

Pro tips

  • Use your non-working hand to lightly hold the elbow of the working arm in place to ensure strict form.
  • Focus on the deep stretch at the bottom of the rep to maximize recruitment of the triceps' long head.
  • Pause for a full second at the top of the rep to fight the band's desire to snap back.

Make it harder

  • Step further away from the anchor point to increase the baseline resistance of the band.
  • Add a 3-second slow eccentric (lowering) phase to increase time under tension.
