An exercise apparatus with base horizontal members forming a base polygon and ceiling horizontal members forming a ceiling polygon and a plurality of vertical members mounted at their lower ends to the base polygon and mounting the ceiling polygon spaced from the base polygon. A human interface permits athletes to exercise, and wheels mounted to the base polygon permit transport of the apparatus and attached equipment to a field or court. The base polygon includes two parallel skids and the human interface may be a pad permitting an athlete to push the apparatus horizontally when none or two of the wheels contact the ground. When no wheels contact the ground, the apparatus may be used in the manner of a weight rack, because the apparatus will not move along the ground without substantial force being applied.

A net assembly for an adjustable basketball goal. The net assembly may include a net, a support frame, and a mounting assembly configured to mount the support frame to a post of the adjustable basketball goal. The net may include a net frame having an upper portion including a plurality of net frame sleeves. The support frame may be configured to support the net, and may include at least one elongated member configured to extend through the plurality of net frame sleeves. The support frame may also include a plurality of support arms, each having a first end portion and a second end portion. The first end portion may be configured to couple to the at least one elongated member, and the second end portion may have a support arm sleeve. The support frame may further include a cross brace configured to couple the plurality of support arms.

A hand immobilizing dexterity trainer glove for improving non-dominant hand dexterity includes a glove body having a dorsal side, a ventral side, a thumb side, and a pinky side. The glove body has a wrist aperture, a finger aperture, and a hand cavity extending from the wrist aperture to the finger aperture. The glove body is configured to receive a dominant hand of a user and extend from below a wrist to past a second knuckle of each finger of the user while covering a thumb of the user entirely within the hand cavity. A wrist tightening mechanism is coupled to the glove body proximal the wrist aperture to tighten and alternatively loosen the wrist aperture. A finger tightening mechanism is coupled to the glove body proximal the finger aperture to tighten and alternatively loosen the finger aperture. The hand immobilizing dexterity trainer glove renders the user's dominant hand unusable.

Systems, methods, and other embodiments associated with instruction production are described. In one example, a system can comprise a difference component that makes an identification of a difference between an actual action of a user and a standard action for the user. The system also can comprise an instruction component that produces an instruction to instruct the user to change from the action of the user to the standard action for the user, where production of the instruction is based, at least in part, on the difference. The system further can comprise a non-transitory computer-readable medium configured to retain the instruction. Additionally, the system can comprise an output component configured to cause disclosure of the instruction.

A basketball training apparatus includes a shot completion sensor, a condition sensor, and a computer. The shot completion sensor determines whether a shot goes through a basketball hoop. The condition sensor senses a physical condition of a basketball shooter. The computer is in communication with the shot completion sensor and the condition sensor, and has a processor for calculating shot completion percentage as a function of the physical condition.

A basketball training apparatus to provide user feedback on shooting form is provided. The basketball training apparatus includes a sleeve disposed around the user's upper arm and forearm, a strut assembly coupled to the sleeve and having an upper strut pivotably mounted to a lower strut, a Hall Effect sensor disposed within the junction of the upper and lower struts, a pair of magnets coupled to the strut assembly's junction, a controller disposed within the strut assembly and electrically coupled to the Hall Effect sensor, and an alert mechanism disposed within the strut assembly and electrically coupled to the controller. Pivotable movement of the upper strut relative to the lower strut to either a first optimal angle or second optimal angle enables the alert mechanism to generate a notification.

A polyhedral substantially cube-shaped training aid approximately the size and weight of a basketball and having a side transition, whereby when the training aid is launched in the manner of a basketball shot the rotation of the training aid provides visual feedback representative of a nature of the rotation of the device in flight. The training aid may include a level indicator device, sound indicator, vibration indicator, and side transitions are generally beveled. The training aid may include visual outer-markings on one or more external surfaces of the aid to visually indicate the nature of the rotation of the device when launched. Alternatively, the training aid is removably placed over the outside surface of a basketball so as to at least partially square off a first perspective of the basketball, the training aid being configured and constructed of material that permits the training aid to become removably affixed to the outer surface of the basketball.

A precision ball-handling training tool develops accuracy and proficiency in basketball control of an athlete performing no-look dribbling of a basketball. A non-opaque tubular member terminating in a body member forms a ring having a perimeter that defines an open space inside the perimeter. A light source is positioned within the tubular member to emit light from and along its length. The emitted light is sufficiently intense to be perceived by the athlete performing no-look dribbling of the basketball within the open space. Opposed light beam switch components positioned at the perimeter of the ring define a line-of-sight across the open space. Power supply and processor circuitry contained in the body member responds to instances of a basketball obstructing the line-of-sight during a basketball dribbling exercise by causing momentary light emissions from the light source to indicate whenever the athlete dribbles the basketball within the open space of the ring.

A system for improving a basketball player's ability to shoot basketballs towards a basketball hoop having an improved ball sensor is disclosed. An interface allows a player to select various locations for a ball ejector to launch basketballs to. A hollow protrusion extends though the net of the basketball hoop and has a microphone positioned therein. A processor compares audio signals generated by said microphone to pre-recorded sample audio signals of a basketball passing through the net of the basketball hoop to determine if a basketball shot was successfully made.

A computer-implemented method is disclosed that includes instructing a human player to perform a plurality of different actions in a determined order with a physical basketball, including actions of bouncing the physical basketball, and obtaining, with one or more electronic sensors, data that characterizes motion of the physical basketball being handled by the human player who is performing the instructed actions at a location. The method also includes communicating the data from the sensors to a console videogame system that is proximate to the location, and graphically representing, in a videogame displayed on a display device, performance by the human player, the performance being affected by the captured data, the representation of performance by the human player being compared against a standard of performance.
