The disclosure features physical activity devices that include (a) a central footrest, configured to receive at least a portion of a foot of a user, (b) a plurality of elongated sleeves, each sleeve having an inner and an outer surface, and being configured to at least partially enclose an elongated tubular support member, and having spaced grooves in its outer surface extending generally perpendicular to a longitudinal axis of the sleeve, and (c) at least two loops extending from the footrest, the loops being configured to be received by the grooves so that the sleeves support the footrest above a surface on which the tubular support members are positioned. The disclosure also features methods of using such devices.

A body-building device including a base body, a swing mechanism and a supporter is provided. The base body is used to support the whole body-building device. The swing mechanism is installed on the base body to enable 360-degree rotation in the circumferential direction or swing to any angle off the central axis of the base body. The supporter is installed at an upper end of the swing mechanism and makes direct contact with human body. With force applied by human body, it drives the swing mechanism to rotate or swing, while the swing mechanism generates a corresponding reset force during swing, thus enabling body building. Fitness methods are also provided.

A removable stretchable cover for exercise equipment has a first wall, a second wall, two side walls and two end walls arranged to form an interior cavity and an opening through which the exercise equipment is appointed to traverse. The opening is formed as a stretchable slit opening adapted to expand to engulf the exercise equipment, and contract in a closed configuration when the exercise equipment is housed within the interior cavity to substantially enclose the equipment within the cover. At least one anti-slip surface is integrated within at least one of the first wall, second wall, two side walls or two end walls. The cover is composed of a thin, stretchy, soft material so that it can be significantly stretched and contracted to snuggly fit over the exercise equipment. Examples of exercise equipment for which the cover is especially well suited include yoga blocks, foam rollers, exercise balls and arm handles of exercise machines.

An exercise board comprising a first top and second top rotatably engaged, wherein the first top has a first cavity and the second top has a second cavity, a board rotatably engaged along a first edge of the first board is rotatably engaged with a first edge of the first cavity, and a step foldable and comprised of a upper step and a lower step; a upper front panel extending between the upper step and the lower step and rotatably engaged to the upper step and the lower step; a lower front panel extend from the lower step and rotatably engaged with the lower step; a front and a rear side panels on each side of the steps being rotatable relative to one another; and a rear panel rotatably engaged with the upper step and both of the rear side panels rear panel.

A multi-mode athleticism movement measurement system includes an athlete-borne acceleration sensor and an athleticism processing device to determine athleticism information based upon one or more timing measurements from the athlete-borne acceleration sensor, the athleticism information corresponding to any of multiple athleticism measurement modes available on athleticism processing device and selectable by a user. A data link between the athlete-borne acceleration sensor and the athleticism rating processing device transmits the one or more timing measurements from the athlete-borne acceleration sensor to the athleticism rating processing device.

A non-mechanical manual combination treadmill/step deck exercise device comprises a treadmill having a strut beam frame with multiple spaced rods with equally dimensioned pipe rollers threaded thereon creating manually operated foot rotatably surface. A step deck conversion simulating a stair climbing workout comprises positioning a deck platform between opposite strut beams over said rollers. The step deck conversion unit is selectively in an operative location with treadmill in a storage location. Swing handles operative in handle assembly mounted to front exterior sides of strut beams of the treadmill foot contact surface pivoting the handles back and forth and thereby provide an arm movement simultaneously with the use of the leg exercise.

A body weight support system includes a tether configured to be coupled to an attachment device worn by a user to couple the user to the body weight support system. A method of providing gait training includes defining a reference length of the tether when the attachment device is in an initial position and defining a threshold length of the tether. A first amount of body weight support is provided during the gait training as the user moves relative to a surface and the length of the tether is less than the threshold length. A second amount of body weight support is provided during the gait training as the user moves relative to the surface and the length of the tether is greater than the threshold length. The method further includes displaying data associated with the gait training on a display of an electronic device.

A functional training rig kit includes a box and a plurality of components adapted to fit within the box. At least some of the components and the box include elements by which the components are adapted to be attached to the outside of the box to provide at least one functional training rig attached to the outside of the box.

An exercise bench for use by a person on a support surface includes a base member having a distal end, a proximal end, a top surface, and a bottom surface. A pair of opposing foot restraints is fixed with, and disposed above and laterally away from, the base member. A riser projects upwardly from the proximal end of the base member and includes a calf restrain trolley slidably mounted thereon. A base plate can be fixed with the bottom surface of the base member, and a U-shaped base extension having two legs extending away from the proximal end of the base member can be attached to the proximal end of the base member. A plurality of attachments may be coupled to the bench to provide different exercises.

A multi-purpose athletic training platform exercise device is provided. A user may stand atop a platform and exercise while connected to a downward pulling source of resistance. This machine allows the user to walk forwards, backwards and side-to-side freely while still having attachment to the resistance source via a connecting means. This will activate all the muscles in the lower body while tractioning the lower back and helping to reduce pelvic tilt. The resistance may be varied during the user effort. The user is able to step off the machine to climb up or down a step, or walk up and down a ramp that may be provided.
