A light, aerodynamic, mini-resistance trainer used with a two-wheel bicycle a vertical connector plate, the connector plate configured to attach to the front, upright side of a bicycle's seat tube, on a bicycle frame using the bicycle's two standard water bottle cage threaded fastener holes and M3 Allen bolts. The upper portion of the connector plate continues around the bicycle frame's seat tube and overlaps the second part of the device, namely the drive system housing. The drive system assembly is comprised of a worm gear on an axle connected to a linear gear rack.

A machine for exercising arms and shoulders and reducing abdominal fat. The machine includes a frame of curve shape. Straps extend from the ends of the frame for tightening the machine over the abdomen. The frame includes an upper rail, a middle rail, and a lower rail, the upper rail and middle rail form an upper track and the middle rail and lower rail form a lower track. An upper set of rollers are mounted in the upper track and an upper handle is coupled to the upper set of rollers. A lower set of rollers are mounted to the lower track and a lower handle is coupled to the lower set of rollers. The upper handle and the lower handle are grasped to pull and push the upper set of rollers and the lower set of rollers to roll back-and-forth in the upper track and the lower track respectively.

An exercise machine for reducing abdominal fat as well as exercising the arms and shoulders. The exercise machine includes a frame that can be of a curved shape to conform to the curves of the abdomen. Straps extend from the ends of the frame for tightening the exercise machine over the abdomen. The frame includes an upper rail, a middle rail, and a lower rail, wherein the three rails run horizontally and parallel to each other along the length of the frame. The upper rail and the middle rail form an upper track and the middle rail and the lower rail forms a lower track. An upper set of rollers are mounted in the upper track and an upper handle is coupled to the upper set of rollers. Similarly, a lower set of rollers can be mounted to the lower track and a lower handle is coupled to the lower set of rollers. The upper handle and the lower handle can be grasped to pull and push the upper set of rollers and the lower set of rollers to roll back-and-forth in the upper track and the lower track respectively.

A locking device for an exercise system may include a locking member having a contact portion and configured to move between a first position and a second position. When in the first position, the contact portion of the locking member is not in mechanical communication with the resistance mechanism of the exercise system, thereby allowing movement of the at least one moveable assembly. When in the second position, the contact portion of the locking member is in mechanical communication with the resistance mechanism of the exercise system, thereby preventing movement of the at least one moveable assembly.

Disclosed herein is a resistance exercise device and methods of using the same. In one embodiment, a resistance exercise device is disclosed comprising a quarter-wheel, a means for attaching resistance to said quarter-wheel, a support means attached to the axis of the quarter-wheel, whereby a user can perform core exercise while moving in a direction parallel to the line of resistance.

An exercise device and a method for its use to aid in the correction of Anterior pelvic tilt. A base has an upper support and a lower support. The base device is strapped around a user's stomach and connected to a rope. The rope passes through the user's legs and is attached to a weight holder behind the user. As the user walks forward, the weight holder is dragged along the floor and the force of the weights on the weight holder pressed the base against the user's stomach and aids in proper alignment of the pelvic region.

A passive-type treadmill is disclosed which includes a closed-loop belt rolling around two spaced apart rollers for providing a running platform, a first and a second handrail parallel to each other and extended upward angling to a surface of the closed-loop belt at larger than 45 degrees, and a towel rack having at least a first and a second clip for stretching a towel between the first and the second handrail.

A modular play and/or exercise hoop having a tear-drop shaped cross section that includes tube segments that are attached to each other by connectors into a circular ring. The connectors have an illumination circuit that project light into each tube segment.

A manual powered treadmill includes a frame; a front shaft assembly coupled to the frame; a rear shaft assembly coupled to the frame; an intermediate shaft coupled to the frame, the intermediate shaft is disposed intermediate the front shaft assembly and the rear shaft assembly; a running belt disposed about the front and rear shaft assemblies, the running belt defining at least a portion of a non-planar running surface; and a safety device coupled to the intermediate shaft. The safety device is operable to substantially prevent movement of the running belt in a first direction and to permit movement of the running belt in a second direction opposite the first direction.

A treadmill is provided according to various embodiments herein. The treadmill includes a frame; a front shaft coupled to the frame; a rear shaft coupled to the frame; and a running belt disposed about the front and rear shafts, wherein the running belt assumes at least a portion of a curved running surface, the curved running surface having a radius of curvature of approximately 88 to 138 inches.
