Single Arm Overhead EZ Extension

The Single Arm Overhead EZ Extension is a strength exercise with an EZ bar for your triceps. Share of the load in the Zulta muscle model: triceps (long head) 44%, triceps (lateral head) 21% and triceps (medial head) 17%.

Level: AdvancedEquipment: EZ barSingle-joint (isolation)Unilateral: one arm or leg at a time

How to do it

  1. Load an EZ bar lightly and grip it in the middle with your working hand, palm facing forward.
  2. Press the bar overhead with the bar horizontal and balanced in your hand.
  3. Bend the elbow to lower the bar behind your head, upper arm pointing up.
  4. Go down until the forearm passes parallel, keeping the bar level.
  5. Straighten the elbow to press the bar back overhead.

Tips

  • Start very light: balancing the bar in one hand is the limiting factor.
  • Squeeze the grip hard so the bar ends do not tip.

Common mistakes

  • Letting the bar tilt so one end drops.
  • Arching and leaning back to finish the rep.

Share per muscle in the Zulta muscle model. The model spreads the load of one rep over 40 muscles, based on EMG and biomechanics research.

One arm at a time. Extending the elbow with the arm overhead puts the long head on stretch, which made it grow more than pushdowns in a direct comparison; lateral and medial heads still assist.
