Stand facing a cable machine with a rope attached at a low pulley. Grab the rope with both hands (neutral grip) and pull it upward and outward, keeping your elbows high and wrists neutral. Focus on driving the movement with your shoulders and upper back, squeezing your shoulder blades together at the top. Control the rope back down to the start position. Maintain a stable torso and avoid using momentum.
Log your cable high pull with rope attachment sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
