Single Arm Triceps Pushdown (Cable)

The single arm triceps pushdown is a unilateral cable exercise that isolates the triceps by extending the elbow against resistance. It suits lifters who want to address strength imbalances between arms and develop symmetrical tricep size.

How to do the Single Arm Triceps Pushdown (Cable)

  1. Attach a single handle to a high cable pulley and grasp it with one hand using a neutral or overhand grip.
  2. Stand facing the cable with your elbow tucked at your side, forearm parallel to the floor, and feet shoulder-width apart.
  3. Brace your core and keep your upper arm stationary as you push the handle down until your elbow is fully extended.
  4. Pause briefly at the bottom, then control the handle back up to the starting position without letting your elbow drift forward.
  5. Complete all reps on one arm before switching to the other side.

Form tips

  • Keep your shoulder down and back throughout the movement to prevent it from rolling forward and taking tension off the triceps.
  • Lock your upper arm against your side so only your forearm moves, ensuring the triceps do all the work.
  • Use a controlled tempo on the way up to maintain constant tension rather than letting the weight pull your arm back quickly.

Common mistakes

  • Letting the elbow drift forward during the eccentric phase reduces triceps tension and turns the movement into a partial rep.
  • Using momentum by rocking the torso or leaning into the movement shifts work away from the triceps and increases injury risk.
  • Gripping too tightly with the hand causes forearm fatigue that limits triceps activation before the target muscle is fully worked.

Sets and reps

For hypertrophy, perform 3 to 4 sets of 10 to 15 reps per arm, and for strength, use 3 to 5 sets of 6 to 8 reps per arm with heavier load.

Frequently asked questions

Should I use a neutral or overhand grip for single arm triceps pushdowns?
Both grips effectively target the triceps, with neutral grip often feeling more comfortable on the wrist and elbow. Try both to see which allows you to maintain better form and feel the strongest contraction.
How do I prevent my shoulder from moving during single arm pushdowns?
Focus on pinning your upper arm to your side and keeping your shoulder blade retracted and depressed throughout the set. Using a lighter weight until you master this position will build better motor control than struggling with excessive load.
Is single arm better than two arm triceps pushdowns?
Single arm pushdowns allow you to identify and correct strength imbalances while also requiring more core stability. Two arm variations let you handle more total load, so both have value depending on your training goals.
