EZ Bar Lying Close-Grip Triceps Extension Behind Head

Body Part: Upper Arms

Muscle: Triceps

Equipment: EZ Barbell

EZ Bar Lying Close-Grip Triceps Extension Behind Head is a bench-based triceps isolation exercise built around a deep elbow bend and a controlled return to full extension. In the shown setup, you lie on a flat bench with your feet planted, hold an EZ bar with a narrow overhand grip, and start with the bar above the chest before lowering it back behind the head. The movement looks simple, but the setup matters because the upper arms, wrist angle, and bench position all determine whether the load stays on the triceps or leaks into the shoulders and lower back.

The main training effect is elbow extension strength through a long range of motion. Triceps brachii is the primary target, with the forearms and shoulder stabilizers helping keep the bar path steady and the elbows from drifting. The close grip and EZ bar shape usually make the wrists feel more natural than a straight bar, which helps you keep tension on the triceps instead of fighting the implement.

A good rep begins with the shoulders settled into the bench, elbows pointing up and slightly in, and the upper arms held almost still. From there, bend the elbows and lower the bar in a smooth arc toward the space behind the head, not toward the face. Keep the movement controlled so the triceps stay loaded through the bottom half of the rep, then reverse the path by extending the elbows until the arms are straight again without snapping the lockout.

This exercise is useful as accessory work for arm development, pressing support, or any program that wants direct triceps loading without a machine. It works well for moderate repetitions with careful tempo, especially when you want a long stretch on the triceps and a strict elbow-driven pattern. The biggest safety point is to keep the elbows from flaring and the ribcage from popping up to save the rep; if the shoulders start taking over or the elbows feel irritated, shorten the range slightly and lower the load until the movement stays clean.

Instructions

• Lie on a flat bench with your feet planted, head near one end, and hold the EZ bar with a narrow overhand grip above your chest.
• Stack your wrists over your elbows, keep your shoulder blades set on the bench, and point the elbows mostly up instead of letting them flare wide.
• Start with the bar over the chest or slightly back toward the forehead, with the arms nearly straight and the triceps already under tension.
• Bend only at the elbows and lower the bar in a controlled arc behind your head while keeping the upper arms as still as possible.
• Let the bar travel until you feel a strong triceps stretch and the forearms are angled back without shoulder pain or rib flare.
• Reverse the motion by extending the elbows and guiding the bar back along the same path to the start position.
• Keep the head, upper back, and glutes anchored to the bench so the bar does not turn into a shoulder movement.
• Exhale as you press the bar up, inhale as you lower it, and finish the set by bringing the bar back to the rack with control.

Tips & Tricks

• Choose the narrow EZ-grip position that lets your wrists stay neutral instead of bent back.
• Keep the elbows pointing up and slightly inward; wide elbows usually turn the movement into a loose shoulder exercise.
• Lower the bar behind the head, not toward the face, so the triceps stay loaded through the bottom of the rep.
• If the bar drifts forward over the forehead, the shoulder angle changes and the triceps stretch gets smaller.
• Use a load you can control through the full descent without bouncing or losing the elbow position at the bottom.
• Keep your feet planted and glutes lightly engaged so your torso stays fixed on the bench.
• A slower lowering phase usually feels better on the elbows and makes the long-head triceps work harder.
• If your elbows ache, shorten the range slightly and reduce the load before you try to push through it.

Frequently Asked Questions

What does the EZ bar lying close-grip triceps extension behind head train most?

It mainly trains the triceps, with the forearms and shoulder stabilizers helping keep the EZ bar steady.

Why use a flat bench for this triceps extension?

The flat bench gives you a stable base so you can keep the upper arms fixed and load the triceps through a longer elbow bend.

Why is the EZ bar useful here?

The angled grip usually keeps the wrists happier than a straight bar, which makes the close-grip position easier to hold.

How far behind my head should I lower the bar?

Lower it until you feel a strong triceps stretch and can still keep the shoulders pinned and the elbows under control.

Should my elbows move during the rep?

They should stay mostly in place with only a small natural adjustment; the forearms should do most of the movement.

Is this a good beginner triceps exercise?

Yes, if you start light and keep the range strict, but it is more demanding on the elbows than a cable pushdown.

What is the most common form mistake?

Letting the elbows flare and the chest arch up so the bar turns into a loose pressing motion instead of an elbow-extension drill.

Can I substitute dumbbells or cables?

Yes, dumbbells or cable lying extensions can be easier to fine-tune if the EZ bar bothers your wrists or elbows.
