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 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.

A reflexive training device having a rotating member that rotates around an axis while also traveling perpendicular to the plain of rotation to present the rotating member at variable vertical locations during use.

A free standing fight simulation workout machine with a fight simulation multi-headed, multi-abdomen, multi-armed apparatus is adapted to be used in conjunction with a slip and counter fight simulation apparatus or stand alone apparatus. The fight simulation multi-headed, multi-abdomen, multi-armed apparatus includes a multi-headed member having at least one head attached to at least one abdomen and at least one arm having a glove appending member. Preferably, multiple heads are attached to multiple abdomens with multiple arm pairs to provide different punch configurations for the user to strike at. The multi-headed, multi-abdomen, multi-armed provides various angles adapted for a user to punch, knee, and/or do a flying knee.

A striking apparatus for all fighting art forms such as boxing to improve a user's fighting skills. The striking apparatus includes a timing ball having a link disposed thereon; an elongated adjustable rope; a swivel mounted to a swivel plate, the swivel plate being mounted to a backboard; the backboard being attached to a frame; the link disposed on the timing ball being attached to the elongated adjustable rope, the rope being attached to the swivel; and the timing ball configured to be struck by the knuckles of a user's fist. Another embodiment of the invention includes a punching apparatus station for all fighting art forms which generally includes the same configuration as the striking apparatus referenced-above. Importantly, the striking apparatus advantageously is a cross between a speed bag, a double end bag, and a maze ball but is beneficially more effective than all three.

A strike training attachment for a heavy bag may include a ball member sized according to the diameter of a typical adult human fist. The ball member may be resilient. The strike training attachment includes a loop member disposed on an outer surface of the ball member. The loop member may be attachably co-operable with a hang-mounting member of a heavy bag.

An entertainment system has an interactive component for an amusement park. The interactive component includes a detection device disposed within a housing and configured to read an identification tag via long range and short range radio communications, an interactive sensor disposed within the housing and configured to detect physical interaction with a portion of the interactive component, a control device communicatively coupled to the detection device and the interactive sensor, where the control device is configured to receive feedback from the detection device and the interactive sensor, an effect device configured to receive a signal from the control device and to generate an effect based on detection of the physical interaction, and a transmitter configured to transmit data to the identification tag based on detection of the physical interaction with the portion of the interactive component while detecting the identification tag within a threshold distance of the interactive component.

An exercise device and an inflatable alternative are provided. The exercise device is composed of a planar base attached to block(s). The block(s) may serve as cushioning or weighted items to enable a variety of exercises. The planar base is securable against a structure such as a door frame. The planar base is also convertible to a bench with shaft(s) that connect block(s) to form legs for the bench. The inflatable alternative includes a top end that is securable to the structure. A bottom end of the inflatable alternative is securable to a user through an ankle cuff. The ankle cuff provides the user a measure of control over a mobility of the inflatable alternative during an exercise.
