Set a cable machine to the highest pulley position and attach a rope or bar. Stand facing away or slightly angled from the machine and grasp the attachment with both hands. Lean forward slightly with a staggered stance and keep your elbows close to your head. Start with your elbows bent and hands near your head or behind it. Extend your arms forward and/or upward by straightening your elbows until fully extended, squeezing your triceps at the top. Slowly return to the starting position with control.
Log your cable high triceps extension sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
