A compression golf swing training apparatus includes a hitting board mounted atop a framework and configured to move downwardly at the point of impact from the golf club striking the hitting board during a golf swing. Specifically, the downward motion of the hitting board, when struck with a golf club, compresses the compression springs in their holder imitating or replicating the feeling a golfer experiences when taking a divot of golf course grass during a golf swing. The system is reconfigurable and interchangeable with distinct compression spring levels held in their individual spring holders replicating and/or imitating the resistance of the ground the golfer experiences playing on hard, soft, and wet golf course grass conditions.

A method can include providing an object having a size smaller than a size of a known regulation object, projecting the object, via a delivery device, toward a trainee, and training the trainee to follow the object. A method can include determining a game parameter of a game trajectory of a sports object that was projected along the game trajectory in a real-time sports event, and based on the game parameters, adapting a delivery device to deliver a training object along a training trajectory that mimics at least a portion of the game trajectory, with the training object being smaller than the sports object.

Described implementations provide a level for measuring a level of a target surface. The level has a base structure having a bottom surface, a top surface, a rear surface, and a front surface, and a bubble level disposed on the top surface of the base structure. The bottom surface is disposed at (1) a desired slope angle of the target surface along a first axis, and (2) a predetermined pitch angle along a second axis of the base structure, the second axis perpendicular to the first axis. The bubble level is disposed on the top surface along the first axis to indicate a slope level of the target surface relative to the predetermined slope angle and along the second axis to indicate a pitch level of the target surface relative to the predetermined pitch angle. The base structure has a ledge extending in an engagement direction along a third axis.

A training or exercise apparatus may have a base and an adjacent movable armature or frame that carries a riding member, or shuttle, or carrier. The carrier has an engagement interface with an element of sporting or exercise equipment. The sporting or exercise equipment is engaged by the user, typically by being grasped. The apparatus defines a physical or virtual schedule describing an arc for a swing in the particular activity. The apparatus may include a manual or electronic means of imposing resistance to the motion. This resistance may be adjustable, and may be programmable as a function of one or both of position and speed. The apparatus may include an array of sensors such as may be used to determine the pre-existing stroke, and such as may be monitored during training to assess progress. The apparatus may be operated passively, or it may be operated interactively in a manner in which real-time feedback causes the apparatus to adjust resistance to the motion.

A method and device for providing performance feedback to a user during a session of using exercise equipment including measuring user input during the session using at least one sensor to gather sensor data, and transmitting the sensor data to a processing device. The sensor data is evaluated to determine at least one of a force metric, a frequency metric, and an accuracy metric. The at least one of the force metric, the frequency metric and the accuracy metric are compared to at least one predetermined performance goal. Audio and/or visual feedback is provided to the user based on the comparison of the at least one of the force metric, the frequency metric, and the accuracy metric with the at least one predetermined performance goal. The audio feedback includes varying a musical playback in at least one of speed, volume, and pitch.

A basketball training system includes a server computer and a basketball training machine. The server computer executes a workout module that manages operation of a graphical user interface that presents a graphical representation of a portion of a basketball court and receives user inputs that define a workout program that includes selected ball delivery locations relative to the visual representation. The basketball training machine receives the workout program and delivers basketballs to the selected ball delivery locations.

The disclosure is directed at a system and method of automated object launching, for replicating ball trajectories, for example with a baseball. The system receives an input from a user that includes trajectory information and then launches an object based on that trajectory. The system includes subsystems that control the orientation of the object to be launched and the position of the system itself. The system also includes a results tracking database to provide analytics and the like for the user.

Controlling weight during a movement includes receiving a set of parameters comprising a nominal weight. It further includes detecting speed during a concentric phase. It further includes progressively adjusting weight during the concentric phase based on the detected speed and the nominal weight.

The present invention provides a competitive weightlifting system capable of interacting with and comparing weightlifting performances of multiple users, and creating competition between such users by displaying a ranked list of performances by those users. The system may include a frame for supporting and guiding a lift bar, sensors mounted to the frame for measuring and refereeing the performance of a user, a controller housed in the frame for tracking and ranking user performances with an interface for creating and logging into user profiles, and a communication device for sharing user performance data with other remote competitive weightlifting systems (e.g., competitive weightlifting systems in other gyms or homes) in order to create a wide-ranging competition between, and ranked leaderboard of, the many users.

A golf club head includes a striking face, a crown and a sole. The crown and/or the sole includes an FRP member formed by a fiber reinforced plastic that contains a fiber and a matrix resin. The FRP member has an average flexural modulus of greater than or equal to 25 GPa. The fiber may contain a carbon fiber. The carbon fiber may have a tensile elastic modulus of greater than or equal to 300 GPa. The fiber may contain a metallic fiber. The FRP member may have a resin content of less than or equal to 40% by weight. The matrix resin may have a glass transition temperature of higher than or equal to 150° C.
