The assist machine triceps push-down is a triceps-focused exercise that is performed on an assisted pull-up or dip station. It is performed by pressing downward on the knee pad of the machine, against the resistance of the weight. It approximates the motion of a triceps cable rope push-down, but with open hands. This variation is often performed for moderate to high reps, such as 8-12 reps per set or more, as part of upper-body or arm-focused training.
