- Beginner

Setup
- Anchor a resistance band to a low point on a power rack or sturdy post.
- Stand facing away from the anchor point in a staggered stance (one foot forward) for better balance.
- 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.
- Engage your core and tuck your ribcage down to prevent your lower back from arching.
How to do it
- Exhale and extend your arm vertically by straightening the elbow until your hand is directly over your shoulder.
- Squeeze the triceps hard at the peak of the movement, ensuring the upper arm remains stationary.
- Inhale and slowly lower the band back to the starting position behind your head, maintaining tension throughout the descent.
- 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.
