Cable Triceps Kickback

The cable triceps kickback is an isolation exercise that targets all three heads of the triceps brachii with constant tension. By leveraging the cable’s line of pull and maintaining strict form, this variation maximizes mechanical tension and mind–muscle connection, making it a go-to for sculpting defined arms.

History and Origins of the Cable Triceps Kickback

The kickback movement dates back to early bodybuilding routines using dumbbells. With the advent of cable machines in the 1970s, lifters adapted the motion to cables to maintain resistance through the entire range. The cable kickback quickly gained favor for its ability to isolate the triceps without requiring heavy loading or risking shoulder strain.

How to Perform the Cable Triceps Kickback

Setup

1. Pulley Height: Set the cable at the lowest position on a single-handle pulley.
2. Grip: Attach a D-handle and grasp it with a neutral grip (palm facing inward).
3. Stance & Bent-Over Position: Stand with one foot forward, hinge at the hips, and rest your free hand on a bench or rack for support. Keep a flat back and core braced.
4. Starting Position: Bend your elbow to 90°, upper arm parallel to the floor, forearm vertical.

Execution

1. Extend: Drive your hand backward by extending the elbow, straightening the arm until fully locked out.
2. Peak Contraction: Squeeze the triceps at full extension for 1–2 seconds.
3. Return: Slowly bend the elbow to return to the start, maintaining elbow position.

Visualize hinging forward, elbow tucked to your side, and launching the handle back like pushing a door closed. Your upper arm stays stationary; only your forearm moves. The slow return keeps the triceps under tension throughout.

Muscle Group Targeted

• Primary: Triceps Brachii (Long, Lateral, Medial heads)
• Secondary: Rear Deltoid (stabilization), Forearm Extensors (grip)

This motion emphasizes the long head at lockout, while the lateral and medial heads share tension throughout. The cable ensures consistent load, even at the bottom of the rep.

Effectiveness Breakdown

1. Stretch and Tension

Maintains constant tension—no slack—maximizing mechanical stress. The bottom position offers a gentle stretch, and full extension creates peak contraction.

2. Safety

Low joint stress when using moderate loads. The fixed upper-arm position prevents shoulder involvement, protecting the elbow and shoulder joint.

3. Progressive Overload Potential

Easy to add small increments via weight stacks. Tempo variations (e.g., paused lockout, 3-second eccentrics) boost time under tension without heavy loads.

Programming Recommendations

• Frequency: 1–2× per week as triceps accessory
• Volume: 3–4 sets of 12–20 reps
• Load: Light to moderate for full control
• Progression: Increase reps, slow eccentrics, or add paused reps before weight

Coaching Tips

• "Keep elbow fixed": Upper arm stays still—only forearm moves.
• "Squeeze at lockout": Pause and contract the triceps hard at full extension.
• "Avoid shoulder swing": No torso movement—stabilize your core.
• "Control the return": A slow 2-3 second negative enhances growth stimulus.
• "Use full range": Don’t cut the motion short; extend fully for peak tension.

Mistakes to Avoid

• Elbow drift: Moving the elbow forward or backward reduces isolation.
• Using momentum: Swinging decreases triceps activation and risks form breakdown.
• Partial extension: Not locking out minimizes contraction and recruitment.
• Overloading: Too much weight forces cheat reps—prioritize control.
• Rounded back: Compromises posture and shifts load away from target.

Scientific Insights

EMG studies demonstrate high triceps activation in isolated kickback variations (Boettcher et al., 2010). Constant tension—ensured by cable resistance—elevates metabolic stress, a key hypertrophy driver (Schoenfeld, 2010). The fixed upper arm further enhances selective triceps engagement.

Final Thoughts

The cable triceps kickback is an essential isolation exercise for lifters seeking detailed arm development. Its simplicity, safety, and consistent tension make it an ideal finisher or accessory movement. Master the form, embrace the stretch, and watch your triceps definition ascend.
