Cable Overhead Tricep Extension

Attach a rope handle to a low cable pulley and face away from the machine. Grip the rope with both hands behind your head, elbows bent and pointing forward. Extend your arms overhead by straightening your elbows until your arms are fully locked out, then lower the rope back behind your head with control.

Pro Tips

• The overhead position stretches the long head of the triceps for maximum growth stimulus
• Keep your elbows pointing forward and close to your head throughout
• Control the eccentric — feel the deep stretch in your triceps before each rep

Muscles worked

Primary: Triceps brachii — specifically the long head, which is the largest of the three tricep heads and the only one that crosses the shoulder joint. With the arms overhead, the long head is placed in a lengthened position (stretched at both the elbow and the shoulder simultaneously), which maximises its loading and growth stimulus.

Supporting: Lateral and medial heads of the triceps (active in elbow extension throughout), core (bracing against the cable’s pull in the overhead position).

Common mistakes

Elbows flaring out: Wide elbows reduce the long head’s contribution and distribute the load across the elbow extensors less efficiently. Elbows should stay close to the head and pointed forward throughout the movement.

Not reaching the stretched position: The stretch at the bottom — where the forearms are behind the head and the long head is at maximum length — is the most important position in this exercise. Stopping short before reaching that stretch eliminates the primary reason to use the overhead variation instead of a pushdown.

Arching the lower back: As the cable pulls from behind, the lower back tends to arch forward to counterbalance. Brace the core and maintain a neutral lumbar spine, especially under heavier loads.

Rushing through the descent: A fast lowering phase removes the eccentric load and shortens time under tension for the stretched long head. Lower the rope slowly — 2–3 seconds — and feel the stretch before each rep.

Programming notes

The overhead tricep extension specifically targets the long head through a stretched range that tricep pushdowns (elbows at the sides) do not reach. For complete tricep development, including both a pushdown-type exercise and an overhead extension is more effective than multiple variations of the same elbow-at-side pattern.

Typical programming: 3–4 sets of 10–15 repetitions, placed at the end of push or arm sessions. It pairs naturally with tricep pushdowns in a superset — the pushdown emphasises the lateral and medial heads while the overhead extension targets the long head, covering the full tricep with two exercises and minimal rest.

Frequently asked questions

Is the cable overhead tricep extension better than a pushdown for tricep size?

They target different heads, so one is not simply better than the other — they are complementary. The overhead extension places the long head in a stretched position that pushdowns cannot reach, and lengthened-position loading is strongly associated with hypertrophy in recent research. If you can only do one tricep exercise, the overhead extension gives you the most long-head stimulus. If you can do two, pair it with a pushdown to cover all three heads efficiently.

Why do my elbows drift out during the overhead extension?

Elbow flare is almost always a load issue or a lack of body awareness. When the weight is too heavy, your body compensates by widening the base to recruit more muscle and reduce moment arms. Drop the weight until you can keep your elbows pointing directly forward throughout the entire rep, then build back up. Performing a few reps in front of a mirror or filming yourself from the side can help you identify how far off your elbows are drifting.

How much weight should I use for the cable overhead tricep extension?

Start lighter than you think you need to. The overhead position challenges your shoulder mobility and core stability in addition to your triceps, so most lifters overestimate how much they can control. A weight that lets you reach the full stretched position at the bottom — forearms behind your head — with elbows staying forward is the right weight. If you lose the stretch or your elbows flare before you get there, reduce the load. Build progressively over weeks rather than chasing heavy singles on an isolation movement.
