Locomotion exercise enhancement equipment comprises a frame which is supported for rolling motion along ground by a pair of axled wheels. The user either pulls or pushes the frame. A rotary load is supported on the frame and operatively coupled with the axled wheels to cause resistance to be imposed on the rotation of the wheels. A selector control varies the degree of coupling of the wheels with the rotary load to thereby vary the effective load imposed on the wheels. Several embodiments of the locomotion exercise enhancement equipment are disclosed. In one of these embodiments the rotary load comprises a disk that is attached to a housing containing a differential mechanism; as the equipment is rolled, the wheels drive the differential mechanism, causing the housing and the disk to rotate. A caliper brake mechanism disposed in association with the disk is set by an adjustment mechanism to impart a desired force against opposite sides of the disk, and thereby set the desired loading.
