Cable Triceps Extension
The Cable Triceps Extension primarily works the Triceps (Long Head) and stabilizer support from the Anterior Deltoid, Pectoralis Major (Clavicular), Wrist Flexors. It is a cable isolation exercise at intermediate difficulty.
The Cable Triceps Extension is an intermediate isolation exercise performed with cable, following a extension movement pattern. It primarily targets the Triceps (Long Head). This is a bilateral pushing movement, meaning both sides work together to generate force.

Muscles Worked
The Triceps (Long Head) is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Anterior Deltoid, Pectoralis Major (Clavicular), Wrist Flexors act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Triceps (Long Head) (triceps)
Stabilizer Muscles
- Stabilizer Muscle Anterior Deltoid (shoulders)
- Stabilizer Muscle Pectoralis Major (Clavicular) (chest)
- Stabilizer Muscle Wrist Flexors (forearms)
How to Perform
Preparation
- Stand or sit on bench or seat with back support just below shoulders.
- Position cable bar behind neck or shoulders with narrow overhand grip.
- Position elbows overhead.
Execution
- Raise cable bar overhead by extending elbows until arms are positioned straight and vertical.
- Lower cable bar behind neck by flexing elbows allowing forearms to travel behind upper arms with elbows remaining overhead.
- Repeat.
Comments
- Let cable attachment pull arm back to maintain full shoulder flexion.
Tips & Common Mistakes
- Fully extend through the range of motion to achieve peak muscle contraction.
- Avoid hyperextending the joint at end range — stop just short of lockout.
- Control the return to take full advantage of the eccentric stimulus.
Programming Suggestions
Adapt your sets and reps to your training goal.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
