A tennis trainer apparatus has a base, a center tube, and an upper structure. The base of the tennis trainer apparatus has a plurality of evenly distributed legs which may have wheels attached for ease of positioning the apparatus in various positions on a tennis court. The center tube is easily adjustable by placing a pin in holes at varying heights. The upper structure has a left arm and a right arm, and each arm has a holding rod attached. A ball with a ball loop is removably attached to the holding rods so that when the ball is struck it can easily travel like a regular tennis ball. The ball loop is attached to the ball through use of a small rod which is inserted into the tennis ball. Ball extenders with at least one and preferably two holding rods attached are used to raise and lower the height of the ball and ball loop, to create any shot in tennis, including a serve. A tennis trainer apparatus can be easily adapted to additional sports.

A physical training apparatus for use in striking training, the apparatus comprising: a frame having a perimeter member extending substantially along a perimeter member plane and a support assembly for supporting the perimeter member above a ground surface such that the perimeter member plane is substantially horizontal, the perimeter member surrounding a central space for receiving an instructor; and a plurality of striking targets suspended from the perimeter member, the striking targets being positioned around the central space to allow a user positioned radially outwardly from the frame, adjacent one of the striking targets and facing inwardly towards the central space, to interact with the striking target while maintaining visual contact with the instructor when the instructor is positioned in the central space.

A balance training system including a riding plate; a load distribution sensor; a load sensor; a mobile body on which the riding plate, the load distribution sensor, and the load sensor are disposed; and a control unit configured to calculate a reference position based on positions of feet of a trainee detected by the load distribution sensor, then calculate a center of gravity position of the trainee based on the load detected by the load sensor, and control a movement of the mobile body based on a change of the center of gravity position with respect to the reference position. The control unit is configured to update the reference position based on the changed positions of the feet of the trainee when the change of the position of at least one of the feet of the trainee is detected by the load distribution sensor.

A projector mount assembly for a sports enclosure includes a frame structure mountable to rear and front cross beams of a sports enclosure, at least one extension bracket secured to the frame structure and mountable to the front cross beam, and a projector mounting arm mounted to the at least one extension bracket and extending forwardly therefrom. The projector mounting arm is adapted to support, and facilitate front-to-back adjustment of, a projector. The projector mounting arm is pivotable relative to the at least one extension bracket to facilitate adjustment of an elevation of the projector.

Outdoor fitness pavilions, and systems and methods related to the same are provided. The pavilions include a floor substructure including floor support members, pillars distributed about a perimeter of the floor substructure, a roof substructure including roof support members, at least some of which are connected to the pillars. The pavilion includes integrated fitness equipment items connected to at least some of the pillars.

Systems, methods, and media for a configurable training system are provided. The configurable training system can include a controller and one or more configurable training devices. The configurable training device can include a housing, a cover coupled to a front surface of the housing, a sensor located within the housing to detect an impact, an indicator located within the housing and configured to emit light, and communication circuitry coupled with the indicator and the sensor. The communication circuitry may be coupled with the controller. The configurable training system may be adapted to various athletic training equipment or other equipment for physical activity.

Exemplary embodiments of a game apparatus and a method of playing the game are provided. In some exemplary embodiments, a method of playing a game is provided, comprising providing a first pole having a first hoop and a second hoop, providing a second pole having a first hoop and a second hoop, selecting a first team having a first player adjacent the first pole and a second player adjacent the second pole, selecting a second team having a first player adjacent the first pole and a second player adjacent the second pole, wherein the first player serves the ball directly to the second player of the first team, and providing a method of scoring wherein points are awarded to the first team if the second player puts the ball in the first hoop, second hoop or both the first hoop and the second hoop of the second pole.

A modular unit for physical activities, outdoors, containing a multi-purpose structural metal frame mounted on a floor of a trailer on wheels, through a fixing point. The multi-purpose structural frame includes two vertical beams linked by longitudinal and transversal longitudinal rails with sliding guides to associate two structurally extendable modules mounted at the front and rear and in turn two horizontal storage cabinets; it is also arranged in a solid way by bolts for fixing both to the multi-purpose structural frame and to the floor of the trailer to a set of individual pulley unit module and to another set of double pulley unit module associated with a weight system with protective covers, and also includes a vertical storage cabinet integrally associated with the multipurpose structural frame.

A protective field screen system that includes a screen frame system (including a screen frame and a protective screen that includes a netting coupled to the screen frame), a base frame to be disposed on a supporting surface, and resilient members. The screen frame coupled to the base frame by way of the resilient members, and the resilient members to deform to facilitate movement of the screen frame relative to the base frame.

A set of two or more whistles. Each whistle of the set sounds differently from each other based on a different type of sound or a different value of a characteristic of sound common to whistles of the set. Sound characteristics may include but not limited to pitch, quality, loudness, and/or duration. Each whistle in the set may be different in appearance from each other in the set. Appearance characteristics may include but not limited to color, numbering, design, light up features, size, and/or shape. Alternatively, the whistles in a set may have a common appearance characteristic, but each whistle may have its own value of the common appearance characteristic. Additional element(s) such as lanyards or mouthpieces may be added to whistles of a set to distinguish them from each other. The set of whistles may be included in a kit having a box for removably storing the whistles.
