Machine triceps extension

Exercise details

  • Target muscle: Triceps Brachii
  • Synergists: None
  • Mechanics: Isolation
  • Force: Push

Starting position

  1. Sit on the triceps extension machine.
  2. Grasp the handles of the machine and place your uppers arms flat on the arm pad, with your elbows lining up with the axis of rotation of the machine.


  1. Keeping your upper arms flat on the arm pad, exhale as you push the handles down until your elbows are fully extended.
  2. Inhale as you reverse the movement in a controlled manner until you feel a mild stretch in your triceps.
  3. Repeat for the prescribed number of repetitions.

Comments and tips

  • Adjust the seat (and the back pad if there is one) so that your upper arms can remain flat on the arm pad throughout the movement. If the seat is too high or too low, your upper arms will not lie flat on the arm pad, in which case your range of motion will be affected.
  • Make sure that your elbows are positioned in line with the axis of rotation of the machine.
  • Do not allow your elbows to flare out; keep your hands, elbows and shoulders in line.
  • Keep your body still (and your back pressed against the back rest if there is one). Only your forearms should move.
  • Use the machine triceps extension to safely and effectively isolate and build your triceps brachii.
