A sports tetrahedron and related systems and methods of use are disclosed herein. The sports tetrahedron is generally constructed by the connection of six bars or edges that form a four-side shape. The tetrahedron may be combined with an electronic system to surprisingly provide an immersive improvement or entertainment experience for a combination of diverse sports, including, but not limited to, boxing, baseball, golf, and soccer.

A striking practice device includes a striking body, a cover, a connecting rod and an outer fixing plate. The striking body includes a hollow portion inside, an assembly hole formed along a direction of the striking body and a cover bole formed along another direction of the striking body. The assembly hole has an inner junction at the hollow portion of the striking body and an outer junction outside the striking body; the cover has a shape corresponding to the cover hole for sealing the cover hole; the connecting rod is installed to the assembly hole and has an inner fixing plate at an end; the inner fixing plate is greater than the assembly hole and disposed at the inner junction; and the outer fixing plate is fixed to the connecting rod and the outer junction of the striking body.

A supporting device for a punching bag includes a hollow tubular pillar; a connector; a flange body; a rubber shock absorber; and a support tray. The connector includes a first end and a second end; the second end is bigger than the first end in diameter; the first end is disposed into the hollow tubular pillar. The connector includes a first connection hole, and the hollow tubular pillar includes a second connection hole. The connector and the hollow tubular pillar are fixed by a locking screw through the first connection hole and the second connection hole. The flange body includes a central blind hole, and the second end of the connector is disposed into the central blind hole. The flange body further includes a radial base. The circumference of the radial base includes a plurality of mounting holes configured to receive a counterweight unit to stabilize the supporting device.

A proximity training device for use in training of activities (FIG. 3), that anybody can use whether they are a beginner, intermediate, or advanced activity enthusiast (user) participating in martial arts or another partner-oriented activities. The user is able to utilize the training device safely allowing them to maintain their physical fitness activities. The user engages the training device maintaining an upright posture and initiates movement thereby activating the training device. It is held within the same proximity of an in-person training partner, allowing the user to practice the fundamental biomechanical responses and other skills required for their preferred chosen activities. The training device is lightweight and easy to store. The arms are easily removed and are adjustable for optimizing user comfort and training device functionality. The training device is easy to assemble and disassemble which allows for easy transport and storage of the training device.

A free standing fight simulation workout machine has a fight simulation headed/multi-headed, with or without arms, member that is adapted to be used in conjunction with a slip and counter fight simulation apparatus or stand alone apparatus. The fight simulation headed member for a free standing fight simulation workout apparatus has at least one main support structure having a mounting means. The headed member comprises at least one head terminating at an elongated neck. When present, the arms are arranged to extend from or come out of different areas of said head, face and/or neck. Preferably, multiple heads are provided. The headed member includes a top mating mounting portion and the neck bottom includes a bottom mating mounting adapted to mount on bungee cords mounted through mounting means on the workout apparatus. The head or heads and protruding arms provide various angles adapted for a user to punch, knee, and/or do a flying knee.

An exercise assembly has a target. At least one compression loop is coupled to the target. A rotatable member is coupled to the at least one compression loop. A support locks the rotatable member at a desired angle. At least one clamp is coupled to the support securing the exercise assembly to a building structure, wherein the at least one clamp moves in a forward and rearward direction relative to the building structure. At least one horizontal locking mechanism is coupled to the support securing the exercise assembly to the building structure, wherein the at least one horizontal locking mechanism moves in a horizontal direction relative to the building structure.

A pedestal punching bag includes a punching bag body. The punching bag body includes an inflatable unit, an elastic isolation layer and a water injection base from top to bottom in sequence. The water injection base includes an elastic box body and a water injection cavity. An upper end of the elastic box body is provided with an opening, and the inflatable body and the elastic isolation layer are weldedly connected to the opening of the elastic box body by hot melting. The water injection base is composed of the elastic box body, and thus can be stored in a folded state. The inflatable body can be folded when it is not inflated, so that the pedestal punching bag can be transported conveniently and has less space occupation when it is not in use.

A striking assembly for martial arts training is provided. The striking assembly includes a base plate configured to be secured to the ground, a support unit having a support plate and a post extending from the support plate, and a striking unit having a main body configured to receive a portion of the post and a striking pad covering at least a portion of the main body. The support plate and the base plate are connected by three or more resiliently deformable isolators. In response to striking impacts, the isolators resiliently deform to create a deflection angle between a normal to the support plate and a normal to the base plate, and resiliently return to their undeformed dimensions at the conclusion of the striking impact such that the normal to the support plate returns to being substantially parallel to the normal to the base plate.
