A handle structure for a chest pull includes a substantially ring-shaped handle having a tapered passage defined radially therethrough. A positioning device including a sphere member is sized to be movably retained in the tapered passage. A shank extends from the sphere member and is connected to a collar member which has an aperture defined therethrough. A positioning member has a head movably retained in the collar member and a tail extending transversely from a mediate point of the head. The tail is positioned corresponding to the collar member so as to position a resilient member between the head and the collar member.
