Infinite Hip Abductor

The movement performed on the abductor machine is called hip abduction, which is the action of moving the legs away from the midline of the body.

Setup: The user sits in the machine with their back supported by a pad and their outer thighs/knees positioned against padded levers. The starting position typically has the legs together or nearly together.
Movement: The user pushes their legs outward against the resistance provided by a weight stack or other mechanism, spreading their legs to a comfortable maximum point. This is the concentric (contracting) phase.
Return: The user then slowly and in a controlled manner brings their legs back toward the starting position, maintaining tension on the muscles (eccentric phase).
