A single-arm pushdown answers a question the two-hand bar version hides: whether your left and right triceps actually press the same. Start with about half your usual per-arm load, keep the free hand resting on the machine so your torso does not rotate, and match reps across sides before adding weight.
How to do the Single Arm Cable Triceps Pushdown
- Stand facing a cable machine with a straight bar attachment at chest height.
- Grasp the bar with an overhand grip and step back to create tension in the cable.
- Position your feet shoulder-width apart and slightly bend your knees.
- Keep your back straight and core engaged throughout the exercise.
- Start with your arm fully extended and perpendicular to the floor.
- Keeping your upper arm stationary, exhale and push the bar down until your arm is fully extended.
- Pause for a moment, then inhale and slowly return to the starting position.
- Repeat for the desired number of repetitions, then switch arms.
Tip: Keep a slight bend at the top on lying extensions to protect the elbow, but lock out fully on cable pushdowns.
Muscles worked
Primary
Triceps · Arms
The triceps straighten the elbow, and overhead variations stretch the long head at the bottom, so you should feel the whole back of the upper arm working with a hard squeeze at lockout.
Secondary
- Forearms — The forearms grip and stabilize the wrist, which should stay straight rather than bending back under the load.
Common mistakes
- Elbows flaring out — on overhead and lying extensions the elbows should stay pointed forward or up, not out to the sides, since flaring turns it into a press.
- Upper arm moving — the upper arm should be pinned in place and only the forearm should move; if the elbow drifts, drop the weight.
- Not finishing the rep — take every rep to a full triceps squeeze; on pushdowns that means a complete lockout for a count.
- Cutting the stretch — on overhead extensions let the weight travel down behind the head until you feel the long head stretch before pressing up.
Where it fits in a workout
Triceps extensions go after the presses in a push session or at the end of an arm day. Superset them with biceps curls.
