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.

Setup
- Attach a straight bar to the low pulley of a cable machine.
- 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.
- Step forward into a staggered stance (one foot in front of the other) for better balance and stability.
- Lean slightly forward from the hips and position your upper arms vertically next to your ears.
How to do it
- Inhale and slowly lower the bar behind your head by bending only at the elbows, keeping your upper arms completely stationary.
- Lower the weight until your forearms reach at least a 90-degree angle or you feel a deep stretch in your triceps.
- Exhale as you extend your arms back to the starting position by contracting your triceps to move the bar in an upward arc.
- 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.
