A swimming aid with a lower back float and an abdominal float, where the floats provide sufficient buoyancy to keep the user's head, neck and shoulders above water when the user is in a vertical position and in a mostly horizontal position. The floats overlap axially so that the user is biased to a vertical position, but can easily rotate between a mostly horizontal position for learning how to swim, and a vertical position, with head, neck and shoulders above the water in both positions, for ease and comfort of breathing, without falling over backwards or sideways.

An exercise device includes a strap. The strap includes a first surface and a second surface opposite the first surface. The strap is configured to be secured to a lower leg of a user such that the first surface of the strap interfaces with the lower leg of the user. The exercise device further includes a ball including an outer surface configured to be held by the user, a first connector extending from the ball, a second connector extending from the second surface of the strap, and a tension member. The tension member includes a first coupling mechanism and a second coupling mechanism at opposite ends thereof and configured to be releasably coupled to the first connector and the second connector via the first and second coupling mechanisms.

A muscle-strengthening passive and active motion device includes: a joint supporter supporting a body part that is bendable or stretchable with a joint region; a driver driving the joint supporter by being combined to the joint supporter; and a controller controlling the driver, wherein the controller is capable of accelerating or decelerating a driving speed of the joint supporter.

An in-goal ball return device, the ball return device is a material implement having a front edge, side edges, and a rear edge. The device is configured for attachment within a goal, the goal having a supporting net mesh. The device has a plurality of closed loops disposed along the rear edge and side edges. The device includes a lacing cord for threading through any number of the closed loops and the net to secure the material implement to the net mesh. The device forms a continuous angled surface between the front and closed portion of the goal when attached.

A flexible grip for a golf club having a tubular member with one or more strips of elastomeric material significantly softer than the elastomeric material of the tubular member provided on the exterior surface of the tubular member. In one version, the strips are on the top flat surface, on other versions, the strips are on the side or both. In another version, an air pocket is provided beneath the strip on the top surface. In another version, a rib or key on a core bar forms a channel on the inner surface of the tubular member during molding. Upon removal of the core bar, a pocket is formed along the grip upon assembly on a club shaft. Upon gripping, the strips and pockets allow depression providing indication of grip pressure. The strips also provide visual aids for user hand positioning.

An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen-depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen-enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

A fluid current producing apparatus assembly for use in a body of water includes at least one receptacle, current producing apparatus and inflation and deflation apparatus. Each receptacle includes a body forming at least one enclosed inside space which further contains at least one independently inflatable and deflatable compartment therein for receipt of a fluid to inflate at least a portion of the receptacle. Each receptacle includes a body having an inner surface, outer surface and at least one internal chamber which is inflated by the inflation and deflation apparatus which modifies the outward shape of receptacle. When the fluid is forced by apparatus over the outside surface of each receptacle or chamber from a front of the apparatus or away from the apparatus, and fluid is drawn in predominantly from the sides of the receptacles back to the apparatus in a circuit of flow. A method is also included.

An inflatable portable ledge apparatus comprises an inflatable platform having a plurality of transverse baffles and a plurality of longitudinal baffles. There are a plurality of suspension straps connected to the inflatable platform. The suspension straps are connected the inflatable platform so that a load on the inflatable platform is distributed across all the suspension straps when the portable ledge apparatus is anchored at a single point.
