Abstract: An ergonomic exercise handle having a semicircular arcuate member for connection to a resistive member and a handle grip having a longitudinal centerline that lies on the diameter of the semicircular arcuate member. A cable resistive member can be attached to the arcuate member with a conventional clip or with a special clip fitted with a small roller to reduce friction. The semicircular arcuate member permits the clip to move to a position in linear alignment with a center of the handle grip and the resistive member. Ends of the handle grip are spaced inwardly from ends of the semicircular arcuate member by circling back loop portions extending past the diameter of the arcuate member and inwardly from the arcuate member ends to the handle grip ends. The loop portions provide for a greater range of movement while still maintaining a center point of the arcuate member within the handle grip.
