Instructions

1

Stand upright inside the cable machine frame with feet shoulder-width apart. Face forward with neutral spine. Position yourself so the cable attachment is at approximately head height or slightly above.

2

Grasp the cable handle or rope attachment with both hands, hands positioned at shoulder height with elbows bent at approximately 90 degrees. Ensure elbows remain fixed at the sides throughout the movement.

3

Lower the cable attachment by bending at the elbows, allowing the forearms to move upward toward the head while keeping upper arms stationary. The movement is controlled and smooth, with tension maintained throughout.

4

Extend the elbows to press the cable downward, returning to the starting position. Lock out the elbows at the bottom of the movement before reversing direction. Maintain constant tension on the triceps throughout the return.

Overview

If you want to isolate and overload the Triceps Brachii, the Cable Alternate Triceps Extension is an excellent addition to your routine. The mechanics of this Strength exercise specifically bias the Upper Arms, while the use of Cable allows for a smooth, natural resistance curve.

Benefits

Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.
Promotes balanced muscular development by effectively recruiting the Triceps Brachii and associated synergists.
Allows for a natural movement path that closely mimics functional daily activities.
Reduces the likelihood of Upper Arms injuries by reinforcing connective tissue strength.
Significantly enhances the structural integrity and power of the Triceps Brachii.

Common Mistakes

Shrugging the shoulders or compensating with secondary muscles rather than isolating the Triceps Brachii.
Losing core tension, leading to poor spinal alignment and reduced power output.
Rushing the repetition tempo instead of focusing on the mind-muscle connection with the Upper Arms.
Using excessive momentum to swing the Cable rather than controlling the eccentric phase.

Muscle Anatomy

The primary driver is the Triceps Brachii. However, the movement also recruits Pectoralis Major, Anterior Deltoid, Anconeus to maintain control of the Cable.

Beginner Tips

If you are new to the Cable Alternate Triceps Extension, focus on mastering the movement pattern with zero weight before adding Cable.
