Exercise guide

Cable Overhead Tricep Extension Straight Bar

  • Intermediate
  • Isolation
  • Rep-based
  • Shoulders
  • Upper arms

This exercise emphasizes the long head of the triceps by placing the muscle in a fully stretched position behind the head. Using a cable ensures constant tension throughout the entire range of motion, which is highly effective for hypertrophy and muscle definition.

Equipment

  • Cable

Setup

  1. Attach a straight bar to the low pulley of a cable machine.
  2. Grasp the bar with an overhand grip, hands shoulder-width apart, and press it overhead while turning your body to face away from the machine.
  3. Step forward into a staggered stance (one foot in front of the other) for better balance and stability.
  4. Lean slightly forward from the hips and position your upper arms vertically next to your ears.

How to do it

  1. Inhale and slowly lower the bar behind your head by bending only at the elbows, keeping your upper arms completely stationary.
  2. Lower the weight until your forearms reach at least a 90-degree angle or you feel a deep stretch in your triceps.
  3. Exhale as you extend your arms back to the starting position by contracting your triceps to move the bar in an upward arc.
  4. Maintain a controlled tempo, taking roughly two seconds to lower the weight and two seconds to extend.

Form checklist

  • Keep your elbows tucked in and pointing forward; do not let them flare out to the sides.
  • Maintain a neutral spine and engage your core to prevent your lower back from arching excessively.
  • Ensure only your forearms are moving; your upper arms should remain fixed throughout the set.
  • Avoid using momentum or 'jerking' the weight at the bottom of the movement.

Pro tips

  • Focus on the deep stretch at the bottom of the movement to maximize recruitment of the triceps' long head.
  • Imagine you are trying to pull the bar apart at the top of the movement to increase the intensity of the contraction.

Make it harder

  • Slow down the eccentric (lowering) phase to 3-4 seconds to increase time under tension.
  • Add a 1-second pause at the bottom of the rep to eliminate all momentum and force the muscle to work harder from a dead stop.
