i just tried this exercise. ive seen a few people do it but i always thought it was too isolated. i started weightlifting by only doing manly, minimal equipment workouts (bench press, dips). but i kept adding more bodybuilding exercises (pulldowns, pushdowns, shrugs). i avoided this exericse until now because it was so “bodybuilder-ish”.
i dropped close grip pushdowns because it wasnt hitting where i wanted to enough so i tried this exercise. you extend a cable across your body, like a cross-body curl played backwards. it hits that outside tricep head really nice. you have so much control with where to place the tension. when i hit a sticking point i can help the cable with my other hand, and tug back on it when i get a peak contraction.
plus this exercise is easy on the tendon
