Abstract: An isolator arms attachment for an exercise system includes a first arm having a first receiver assembly to engage with a first user engageable device; a first shaft coupled to the first arm and to connect the first arm to the exercise system; and a first counterweight assembly coupled to the first arm near a second end. A second arm having a second receiver assembly to engage with a second user engageable device; a second shaft coupled to the second arm near the second end and to connect to the exercise system; and a second counterweight assembly coupled to the second arm near the second end. The first arm and the second arm are to be manipulated by a user such that the first arm and the second arm provide resistance to the user.
