The ampullae down is an exercise focused on the relaxation of the latissimus dorsi. The goal is to provide a wide range of relaxation through the unique wide range of motion of the exercise, maximizing the engagement of the entire latissimus dorsi for control. In this process, it is better to keep the elbows fixed without bending or extending them too much, so that the arm strength is minimized. In this exercise, conversely, the shoulder joint and elbow are fixed in place to reduce the involvement of other muscles, and it is characterized by pulling only with the triceps. To summarize lightly, you can understand it as a difference in whether the shoulder joint or the elbow joint is moving.

Isn't amp pull-down a back exercise?
