Attach a rope to a high pulley on a cable machine. Stand facing away from the machine and grasp one end of the rope with one hand. Step forward into a staggered stance and bring your arm overhead with your elbow bent and close to your head. Keeping your upper arm stationary, extend your elbow to straighten your arm overhead. Squeeze your triceps at the top, then slowly lower the rope back behind your head with control. Complete all repetitions on one arm before switching to the other, maintaining stability and proper form throughout.
Log your cable overhead single arm triceps extension (rope attachment) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
