What muscles do Cable Lying Triceps Extensions work?

This exercise primarily targets the triceps brachii, focusing on all three heads of the muscle for balanced arm development. While it’s an isolation movement, stabilizing muscles in the shoulders and forearms are also engaged to control the weight.

What equipment do I need for Cable Lying Triceps Extensions?

You’ll need a flat bench and a low pulley cable machine with a straight bar or EZ bar attachment. If you don’t have access to cables, you can substitute with an EZ curl bar or dumbbells, though the resistance curve will be different.

Are Cable Lying Triceps Extensions suitable for beginners?

Yes, beginners can perform this exercise with light weights to learn proper form and elbow positioning. It’s important to start slow, focus on controlled movements, and avoid locking out the elbows completely to reduce joint stress.

What common mistakes should I avoid when doing Cable Lying Triceps Extensions?

How many sets and reps should I do for Cable Lying Triceps Extensions?

For muscle growth, aim for 3–4 sets of 8–12 controlled reps. If training for endurance, lighter weights with 12–15 reps per set can be used, ensuring each rep is performed with good form.

How To Do

Lie on a bench facing a low cable pulley, holding the attachment with an overhand grip.

Step-by-Step Instructions

Begin by attaching a straight bar or rope to a low pulley cable machine. Adjust the weight to your desired level.
Lie flat on a bench with your head positioned near the cable machine. Ensure your feet are flat on the floor for stability.
Grab the bar or rope with an overhand grip (palms facing down) and extend your arms fully so the bar is directly above your chest.
Slowly lower the bar towards your forehead by bending your elbows, keeping your upper arms stationary and close to your head.
Pause briefly when the bar is near your forehead, ensuring control and avoiding any sudden movements.
Push the bar back to the starting position by extending your elbows, fully contracting your triceps at the top.
Repeat for the desired number of repetitions, maintaining proper form throughout the exercise.
