A portable net system for a racquet sport. The portable net has a first stanchion and a second stanchion. The first and second stanchions are configured to mate together forming a carrying case. The portable net includes a self-retracting net that resides within the first stanchion, and which unspools from the first stanchion according to a desired width of a court. The leading edge of the net clips or otherwise fastens to the second stanchion. Thus, as the first and second stanchions are separated, the net unspools forming a net for a racquet sport. Each of the first and second stanchions additionally includes a base that provides support for the portable net in a vertical orientation.

A suspension training based functional fitness element (11, 31) comprising: an essentially planar element (22) having an upper edge, a lower edge and two side edges, said planar element (22) being designed to form a pivotable connection to a support element (32) along said upper edge of the planar element (22), a first elongated element (23, 32, 52) connected to said planar element (22) at a first connection point at said lower edge of the planar element (22), a second elongated element (23, 32, 52) connected to said planar element (22) at a second connection point at said lower edge of the planar element (22), and a first and second handle (24), said first and second handle (24) being connected to said first and second elongated elements (23) respectively, whereby that said first and second connection points are arranged such that there is a horizontal offset between the first and second connection points and such that there is a vertical offset between the first connection point and the pivotable connection and a vertical offset between the second connection point and the pivotable connection.

A system may include a virtual reality system configured to present one or more virtual objects via an electronic display. The system may also include one or more inflatable objects that correspond to the one or more virtual objects, such that the one or more inflatable objects matches one or more shapes of the one or more virtual objects. The system may also include a processor configured to cause at least one of the one or more inflatable objects to inflate based on feedback from the virtual reality system.

A retrofit trampoline and pole device that may be use with a water structure for exercise, adult entertainment, and/or recreational purposes. An entertainment system that may comprise a trampoline and a pole that may be used for exercise, adult entertainment, and/or recreational purposes.

A sand training bag for sand and/or mineral training in an open and closed configuration. The sand pit training bags includes a sand pit training bag configuration comprising at least one fastener and at least one overlaying fabric around the perimeter to open flat on a surface. The sand training bag includes attachable wall structure, wherein the surface attachable wall structure is configured with a sand pit training bag in an open configuration visible relative to a sand or mineral pit held by one or more fasteners. The sand training bag includes a single sand pit training bag, wherein the single sand pit training bag is convertible to a single sand pit with at least one attachable perimeter wall around the perimeter of the open sand or mineral receiving surface configuration, wherein a top cover is configured to be viewed as a sand or mineral pit closed configuration.

A sports target device having a base and a frame member projecting upwardly from the base when the device is in the use position. A panel is attached to the frame in a manner that produces a loud noise when struck by a projectile. The panel may include targeting indicia. The noise that is produce can be loud and of prolonged duration. Such a noise would be appreciated by some athletes, particularly young ones, who will thereby be encouraged to keep practicing.

A training harness system for snow sport training includes: a training harness that is wearable by a student, including: a harness body with a central leash receiving structure and left and right leash connector assemblies, each including at least one leash receiving structure with an elongated aperture; and a leash assembly, including first and second leashes, each including: an elongated leash member; a leash handle; and a leash connector with a hook portion, that includes an elongated hook member, such that the elongated hook member detachably connects with the at least one leash receiving structure; such that the training harness system enables a trainer to control and guide skiing or snowboarding of a student. The training harness system is configurable for beginner, intermediate, and advanced students, with different connections of the right and left leashes to the training harness.

A teaching aid for rotary motion of a pedal-driven wheeled vehicle features an arm configured to span from a lower end thereof positioned at a rotary pedal assembly of the pedal-driven wheeled vehicle in an upwardly and longitudinally inclined orientation to an upper end of the arm positioned at a longitudinally spaced location from the seat of the pedal-driven wheeled vehicle, which upper end is configured for gripping by a user. The aid further features a connector supported on the arm at or adjacent the lower end thereof, which is configured for attaching to the rotary pedal assembly on one side of the vehicle and at a spaced location from an axis of rotation of the rotary pedal assembly such that the arm acts as an extension for the user to drive rotary motion of the rotary pedal assembly by the user's hand.

A training device for use with a goal having a pair of posts and a crossbar, includes a pair of side panels, each side panel being disposed adjacent each of the pair of posts, each side panel including a pair of first arms disposed parallel with the pair of posts, upper and lower transverse members extending between the pair of first arms, a first netting covering the area defined by the pair of first arms, and the upper and lower transverse members, and at least one hinge coupling one of the first arms to an adjacent post.
