The arm exercise uses four pistons, two per arm thus making each arm independent of the other during exercise. This is beneficial because this also allows for the resistance to be different each arm, the above pictures show the arm exercise assembly.
The pistons used have 12 resistance settings that are changed by rotating the gray cuff on the piston.
