    摘要: An exercise apparatus includes a treadmill mounted on a frame with a rotating conveyor providing a moving surface for a person to exercise upon. The exercise apparatus also includes at least three static foot support portions connected to the frame allowing the person to stand on the exercise apparatus and not on the moving surface. First and second static foot support portions of the at least three static foot support portions are on either side of the rotating conveyor, and a third static foot support portion of the at least three static foot support portions is located in front of the moving surface approximately below a grasping handle.

    摘要: Embodiments of the present disclosure relate to a two-person exercise wheel. The two-person exercise wheel may include an exercise ring, a non-equilateral parallelogram linkage mechanism, a tension spring, and a suspension seat. When the ring is rotated, the non-equilateral parallelogram linkage mechanism may be rotated by a rocker arm. In some embodiments, the gravitational forces and the tension spring connected between the two seats act on the ring via the non-equilateral parallelogram linkage mechanism and the rocker arm. In some embodiments, the supporting force of the ring may pass through a circular center. Further, the gravitational forces may act on the non-equilateral parallelogram linkage mechanism and the persons on the seats may pedal to enable the ring to gain a rotation torque. Further, the tension spring may adjust the torque between the seats and the circular center when the two seats are in positions different from each other.
