Abstract: The present invention provides a mountable arm assembly for fitness equipment, comprising two arm members and a connector for pivot connection of the two arm members. The two arm members respectively provide a plurality of assembly portions for length adjustment of the tension arm. The connector is formed with a pivot connection portion and a plurality of eccentric positioning portions. Specifically, an adjustable disposing angle is formed between the two arm members, and at least one of the two arm members sets the disposing angle through at least one eccentric positioning portion. The arm assembly can be mounted on fitness equipment and can swing back and forth through the pivot connection portion. The users can select one assembly portion on each of the two arm members for required tension arm lengths and add an applied force and a resistance force respectively on the two assembly portions. The invention effectively solves the problem that the existing fitness apparatuses do not offer adjustment of the tension arm length or the disposing angle.
