All 3 variations still train all 3 heads — these are just biases based on joint position, grip, and tension. No single exercise “isolates” one head choose based on what you want to emphasize and how it feels for you. Pronated (overhand) grip → Targets all 3 heads → Greater emphasis on the lateral head * Pronated grip = more internal rotation elbow extension Supinated (underhand) grip → Targets all 3 heads → Slightly more medial head involvement * Supination shifts elbow mechanics → increases med

Triceps 101 | overhead triceps extension

Prove me wrong, but once you start doing cable overhead triceps extensions one arm at a time, you'll never go back to doing them both arms at a time with the rope. That said, not all setups are created equal. My opinion is that the best way to do cable overhead triceps extensions is facing sideways, with the cable behind you and the working arm on the side facing away from the cable. #fyp #fitness #gym #bodybuilding
