For most lifters this straight-bar pushdown is the first triceps movement worth learning: the stack makes small jumps easy, and standing tall with elbows pinned teaches strict elbow extension before you ever lie under a skull crusher. The overhand straight-bar grip also works the forearms harder than a rope does.
How to do the Cable Triceps Pushdown
- Attach a straight bar to a high pulley cable machine.
- Stand facing the machine with your feet shoulder-width apart and a slight bend in your knees.
- Grasp the bar with an overhand grip, hands shoulder-width apart.
- Keep your elbows close to your sides and your upper arms stationary.
- Exhale and push the bar down until your elbows are fully extended.
- Pause for a moment, then inhale and slowly return the bar to the starting position.
- Repeat for the desired number of repetitions.
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.
