The Cable Machine Overhead Triceps Extension exercise works your triceps.
We're gonna be performing an overhead triceps cable extension. What we wanna do is to hook up the bar to the cable pulley apparatus and then move it to the uppermost position. Now, Lea is gonna take the bar. She's gonna position herself in a fairly wide stance, so she has a nice center of gravity. Elbows over the in of her head and she's just kind press forward. Notice how she keeps her upper arm stable. The only thing that moves is the forearm and this works the long head of the triceps, which prevents the upper arm from getting a giggly motion.
