A ball net structure arranged to be portable, collapsible, and able to be configured into different arrangements for different nets and/or different sports-related activities. The ball net structure comprising a base structure including at least one support portion, at least one base extension, and at least one base extension hinge, wherein the at least one support portion and the at least one base extension are coupled to the at least one base extension hinge. At least one rod is removably coupled to the base structure and received by a net, wherein the net is adapted to exert a force on the at least one rod causing the at least one rod to exert a force onto said base structure.

A tennis training system may include a target mat including an intersection point and radial lines extending from the intersection point to visibly define sections. A target device may align with the target mat. The target device may include a body, a target assembly coupled to a first end of the body to define a target opening, and a base coupled to a second end of the body opposite the first end.

Martial arts conditioning apparatus and methods of manufacture and use. In one embodiment, the martial arts conditioning apparatus includes a mounting post that includes a kicking post, the kicking post including a hemispherical structure disposed on a shaft of the kicking post; a base support structure that is configured to be mated with the hemispherical structure, the base support structure including a surface that is coupled to the martial arts conditioning apparatus via one or more of a first resistive apparatus and/or a first dampening apparatus; a multi-rod height adjuster assembly that is disposed adjacent the base support structure; and a resistive ball-socket mechanism that is coupled to the multi-rod height adjuster assembly via the use of a coupling mechanism.

A batting tee system includes a base, a first carriage moveably coupled to the base, and a second carriage moveably coupled to the first carriage. The second carriage may hold an external system having a neck and a ball holder. The batting tee system further includes a first actuator attached to the base, and a second actuator attached to the first carriage. The first actuator may move the first carriage and the second carriage along a first horizontal axis relative to the base. The second actuator may move the second carriage along a second horizontal axis relative to the base and the first carriage. The batting tee system further includes a control system that may cause the first carriage and the second carriage to move to random positions along the first horizontal axis and the second horizontal axis.

A beverage holding support structure, for use in a pool, includes a base configured to be disposed at a non-equilibrium sloped position within a pool relative to a horizontal plane and parallel to a sloped bottom surface of the pool, a base connector connected to the base, an articulating mechanism adjustably coupled to the base connector and extended upwardly therefrom, at least one extension pole aligned with a centrally registered longitudinal axis and statically affixed to an upper portion of the articulating mechanism, and a cup holder tray attached to the at least one extension pole. The beverage holding support structure has a center of gravity configured to prohibit the base from being tipped over from the non-equilibrium sloped position while the cup holder tray is maintained at a horizontal position parallel to the horizontal plane above a top water level surface of the pool.

A clear vinyl flat punching bag sheet, with a roll down—roll up action is disclosed, which comprises of clear vinyl, an inverted graphic image applied to the backside of the clear vinyl sheet preferably of a boxer but not limited to . One 1/4 polyethene tubing, one aluminum molding track, two velcro strips, two metal weights, wherein a clear vinyl sheet preferably 28″ wide but not limited to a lesser width of 22″ or of a greater width of 36″. The clear vinyl sheet is preferably 48″ in vertical length but not limited to being of a lesser length of 24″ or of a longer length of 72″ or greater . The gauge of the clear vinyl sheet is preferably 0.020 but not limited to being of a lesser gauge of 0.008, 0.010, 0.012, 0.016, or of a thicker gauge of 0.030, 0.040, 0.080.

An attachment kit for a heavy bag includes a securing strap having a length between a first end and a second end and a securing mechanism that retains the securing strap about a perimeter of the heavy bag. The kit includes a plurality of connecting straps, each of the plurality of connecting straps having a length between a first connecting end and a second connecting end, wherein the first connecting end is positioned about the securing strap. The kit includes a tether having a top end and a bottom end, the top end couples to each of the second connecting ends of the plurality of connecting straps and a bottom end is couples to an anchor. When the securing strap is secured about a perimeter of the heavy bag and the tether is secured to the anchor, movement of a lower end of the heavy bag is limited.

An exercise arrangement includes a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The support may be a platform movably mounted to a base. A roller and track arrangement may be provided between the platform and the base, to provide movement of the platform in the axial direction relative to the base as well as an axially neutral position of the platform relative to the base. The roller and track arrangement may be in the form of one or more curved roller and track engagement surfaces that extend in the axial direction and that provide a gravity bias of the platform toward the neutral position. The roller and track arrangement may provide tilting movement of the movable platform about the tilt axis. A tilt biasing arrangement biases the platform toward a neutral tilt position relative to the base.
