Cable Alternate Triceps Extension
Exercise 0149 is an exercise for arms, shoulders, and core that uses cable machine and cable handles to build useful training quality through controlled movement. The Cable Alternate triceps Extension trains one triceps at a time using cable resistance. The main goal is to perform each repetition with enough control that the target area, posture, and breathing stay consistent from the first rep to the last.
The primary emphasis is triceps, while shoulders and core assist with stability and clean execution. In anatomy terms, the main work centers on the triceps brachii, with help from Deltoids and Rectus abdominis. It mainly works the triceps, with the shoulders and core helping stabilize.
A strong set starts with the setup, because the starting position determines whether the rest of the repetition feels stable or rushed. Set up at a cable machine with a handle in one or both hands. Brace your core and position your upper arm securely. Extend one elbow to move the handle away or down, depending on the setup. Keep the body organized before you move so the working muscles can guide the exercise instead of momentum taking over.
During the repetition, use the instructions as direct coaching cues rather than trying to force a bigger range than you can control. Return under control and switch to the other arm. Continue alternating with clean elbow movement. Continue alternating with clean elbow movement.
The best training effect comes from clean, repeatable reps rather than rushing for a higher count. Keep your upper arm from swinging. Use a light to moderate load. Control the return phase. Do not twist your torso to finish reps.
Use Exercise 0149 in the part of the workout where focused technique and controlled tension fit your goal, such as a warmup, accessory block, core session, or targeted strength circuit. Stop if the cable angle irritates your elbow. Alternating arms helps each triceps work independently and can reveal side-to-side differences. Keep the shoulder mostly stable so the elbow extension targets the triceps.
