A transformable balance board that may be alternately used as a balance board or wobble platform and a wheeled board or roller platform. The balance board includes a rigid platform preferably covered with a closed-cell yielding foam pad layer on top on which a user can support his or her weight. When used as a wobble platform, a relatively large central fulcrum member extends down from the rigid platform so that the board wobbles with no stable horizontal position. In a second usage configuration as a wheeled board or roller platform a plurality of sturdy wheels or rollers retracted into the underside of the rigid platform are extended vertically downward from their retracted positions. Because the vertical height of the wheels is greater than the vertical height of the fulcrum member below the rigid platform, the wheels make contact with the ground and the fulcrum is lifted up and out of contact with the floor below.

The present invention relates to a rowing seat (1) for rowing and kayaking boats and exercise equipment, comprising a first face (2) adapted to support and carry a user, a second face (3) arranged opposite the first face, a first end (4) and a second end (5), a first side (6) and a second side (7), and a longitudinal axis (8) extending between the first end and the second end, wherein the first face (2) comprises a middle section (9) arranged substantially between the first and second sides (6, 7) and extending from the first end (4) towards the second end (5) with a length of at least 8 cm, the middle section (9) having a substantially convex support face (10) extending along the longitudinal axis, the support face (10) being adapted to support at least 50% of the user's weight during use of the rowing seat. The present invention also relates to a rowing, kayaking or exercise system comprising a rowing seat according to the present invention.

An exercise apparatus comprises a platform having a front roller, a rear roller and an endless belt mounted around the front roller and the rear roller for allowing a user to perform a first exercise type of a relatively lower resistance or a second exercise type of a relatively higher resistance. A front frame is mounted at a front side of the platform and has at least one holding portion adapted to be grasped by the user. One or more control interfaces controls the first exercise type and the second exercise type.

Ball collection apparatus and methods for forming ball collection apparatus are disclosed. In one aspect, a ball collection apparatus includes a netting body that includes netting, edges around a perimeter of the netting, and corners along the perimeter of the netting at intersections of the edges, the edges including a front edge, a back edge, a first side edge, and a second side edge, a plurality of connectors attached to the netting body at the corners of the netting body, a plurality of fasteners attached to the netting body, and a guiding device operably coupled to the netting proximate an aperture defined by the netting, the guiding device having a weight to produce a slope in the netting sufficient to guide a sport ball to exit the netting body via the aperture.

A rower folding structure includes a main frame provided with a stopper at the front and a screw lock seat with a locking bolt at the bottom, and a second frame pivotally connected to the front of the main frame and pivotable relative to the main frame between an unfolded position and a folded position. The second frame is provided with a buckle member at the bottom, which has an opening for the passing of the locking bolt. When the second frame is at the unfolded position, the buckle member abuts the screw lock seat and the locking bolt tightens the buckle member; when the second frame is at the folded position, the second frame abuts the stopper. In this way, the overall volume of the rower during transportation can be reduced.

A rower includes a main frame provided with a slide rail that has a front and an opposing rear end, a seat cushion slidably arranged on the slide rail, and a resistance device installed under the slide rail and adjacent to the rear end of the slide rail. Thereby, by changing the resistance device to be arranged in the rear half of the rower and arranged under the slide rail, the overall volume of the rower can be further reduced.

Devices, systems, and methods for training baseball and softball batters, to identify types of pitched balls (fast ball, curve ball, slider and changeup) and locations (strike or non-strike zone) of pitched balls in order to increase hitting accuracy A motion sensor can be triggered by the leading foot of a pitcher. The motion sensor can use cone or fan shaped sensor to detect the passage of a pitched ball from the pitcher. When the motion sensor is triggered, a signal can be sent to a black out lens that blocks the vision of a hitter being trained to identify the types and locations of the pitched balls. The training includes changing the lens from transparent to opaque at selected distances between the hitter and the pitcher. Batters can be trained to keep their eyes on the pitched balls until the ball reaches the batter. Golfers can be trained to not have to look up when their club hits the ball, where the black out lens are go opaque when the golf swing passes into the motion sensor.

A swing practice device for emitting light at impact through self-generation enables an impact moment to be checked with the naked eyes without needing a battery by emitting light at an impact time point through self-generation during swinging by using a golf club, a baseball bat, and the like. The swing practice device includes a power generation magnet provided to a shaft so as to slide in the longitudinal direction of the shaft during swinging; a power generation coil provided on the circumference of a section in which the power generation magnet moves; a light-emitting lamp connected to the power generation coil so as to be turned on by the movement of the power generation magnet; and a magnet control means for preventing the movement of the power generation magnet at a set swing speed or lower.

A body held sparring device configured for either striking or being hit with the addition of a secondary target. The secondary target is offset from the sparring tool and designed to yield when struck, rather than transmit dangerous torque to the body part holding the sparring tool. Additionally, the sparring tool can further incorporate additional sparring tools, additional secondary targets and or additional control body points. A body held sparring device comprising: a U-shaped structure, at least a first sparring tool, and at least a first target wherein the first sparring tool is configured to be controlled independently of the U-shaped structure and to simulate punches being thrown by an opponent such as jabs and crosses. Wherein the first target is configured to yield when struck to reduce the amount of torque received by the body part through the structure.

A portable target assembly for use in a sport wherein a projectile is propelled at a goal, the portable target assembly comprises a front face and rear face separated by a solid material, and a magnet secured to the portable target assembly allowing the portable target assembly to be magnetically attached to a goal post or crossbar. A magnetically receptive material is coupled to a goal post or crossbar when the post or crossbar is not made of a magnetic material. A method of sport training, comprising the steps of: providing a portable target assembly having a front face and a rear face separated by a solid material with a magnet secured thereto; securing the portable target assembly to a goal post or a cross bar of a goal such that the portable target assembly protrudes into a goal region of the goal; launching a projectile at the portable target assembly.
