An example golf bag including a top cuff including a circular recess in an exterior surface of the top cuff, the circular recess including a through hole, wherein the top cuff has a top cuff hand width (W.sub.TC-HAND) greater than 75 mm. The golf bag may also include a knuckle including an interior knuckle boss at least partially housed inside the circular recess, the knuckle boss including a through hole aligned with the through hole of the circular recess; and a leg-receiving portion. The golf bag may further include a leg connected to the leg receiving portion of the knuckle; a fastener extending through the through hole of the knuckle boss and the through hole of the circular recess; and an actuator handle coupled to the top cuff and in contact with the knuckle, wherein downward pressure applied to the actuator handle causes the knuckle to rotate about the fastener, wherein rotation of the knuckle causes the leg to deploy into an expanded state.

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.

A swimming machine comprising a housing adapted to be mounted to an interior wall of a swimming pool. The housing comprising a hydraulic motor connected to an impellor mounted within the housing for producing a current of water in the pool when in use. The swimming machine further comprising a hydraulic pump stored outside the housing operably connected to the hydraulic motor mounted within the housing, an electric motor connected to and powering the hydraulic pump, an inverter drive system connected to, powering and controlling the electric motor. Wherein in use the speed of the current produced is controlled by the inverter drive system.

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.

A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.

A countercurrent swimming system for swimming pools or swimming baths comprises a housing box which has at least one water inlet opening and at least one water outlet opening, a propeller for generating a water flow, which propeller is arranged in a flow channel, the flow channel opening into the at least one water outlet opening downstream of the propeller and hydraulically communicating with the at least one water inlet opening upstream of the propeller, a drive motor for the propeller. The countercurrent swimming system includes the drive motor arranged outside of the housing box and in that the propeller and the drive motor are coupled to one another via a magnetic coupling.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A sports shaft having an elongated body having a perimeter defined by a plurality of main walls with adjacent ones of the main walls being interconnected through a corresponding one of a plurality of edge walls, the edge walls being spaced apart around the perimeter. A respective bumper extends along at least part of length of at least one of the edge walls. The main and edge walls without the respective bumper have a first stiffness along a longitudinal direction of the shaft, and a combination of the respective bumper with the at least one of the edge walls has a stiffness along the longitudinal direction greater than the first stiffness. A method of making a sports shaft is also discussed.

Muscle resistance apparatus comprising a framework, at least one resistive force and a movable section. The movable section is linked to a resistive force, wherein a first part of the movable section is attached to the framework by a connection whereby it can be temporarily displaced, and a second part of the movable section is connected to the first part of the movable section by a second connection whereby it can be temporarily displaced. The first and second parts of the movable section are independently movable with respect to one another in an angular and/or linear fashion.

An exercise apparatus comprises a platform having a front roller, a rear roller and an endless belt mounted around the front roller and the rear roller for allowing a user to perform a first exercise type of a relatively lower resistance or a second exercise type of a relatively higher resistance. A front frame is mounted at a front side of the platform and has at least one holding portion adapted to be grasped by the user. One or more control interfaces controls the first exercise type and the second exercise type.
