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.

A method can include projecting an object toward an impact device along a trajectory, receiving the object at a target zone of the impact device, a trainee striking the impact device at an impact zone with a sports tool, and scoring a performance score of the trainee to impact the impact zone at an appropriate time compared to an arrival time of the object at the target zone. A method can include projecting an object toward a target along a trajectory, receiving the object at an actual arrival position at the target, wherein the actual arrival position is either inside a target zone or outside the target zone, and where a trainee is configured to send an indication when the trainee expects the object to arrive inside the target zone, comparing the indication to the actual arrival position, and determining a performance score based on the comparing.

Systems and methods for providing climbing walls are discussed. While such systems and methods can include any suitable component, in some cases, they include a climbing wall that has a base member and a climbing surface that includes at least one climbing hold. In some cases, the climbing surface is pivotally connected to the base member. Additionally, in some cases, the system includes an anchor that is configured to adjustably retain the climbing surface at an angle with respect to the base member. In some cases, the system further includes a camera, microphone, and/or display that are configured to allow a climber to have audio and/or visual interactions with another person in a remote location (e.g., for training, competition, etc.). In some cases, at least one climbing hold on the climbing surface comprises a sensor that is configured to indicate when a climber has used that hold. Other implementations are described.

A self-propelled waterborne wave riding system includes a vessel having at least one motor and control system for navigating and propelling the vessel along a body of water. A rider section is located along the top of the vessel and includes a lower platform at the front of the vessel, an upper platform at the back of the vessel, and an elongated angled ride surface that extends between the upper and lower platforms. A pump system is provided along the vessel and includes an impeller assembly that is mechanically coupled to an inboard motor and a water pipe. Water received by the impeller is directed through the water pipe to a horizontally oriented nozzle in the lower platform which pushes the water over the ride surface. Openings in the upper platform return the used water into the body of water.

A golf bag includes a divider top, a base, and a plurality of stays comprising a first stay, a second stay, and a main stay having a first end opposite a second end. The golf bag further comprises a top hinge coupled to the first end of the main stay. A base hinge can be coupled to the second end of the main stay, wherein the main stay can be hingedly connected to the divider top by the top hinge, and the stay can be hingedly connected to the base by the base hinge. Other embodiment of the golf bag are also described.

A hitting system for sports training includes a ball attached to a flexible mast. The flexible mast may be mounted to a base with more than five sidewalls, which inhibits movement of the system in any one direction after the ball is struck by the user. The mast may project upward from the base. Some embodiments include a weighted basket, which may be filled for example with a plurality of the same type of ball mounted to the flexible mast. Some embodiments may be configured for training with lightweight balls, for example pickle balls. The mast may include a securing mechanism which attaches around one of the pre-existing holes of the ball's shell. In some embodiments, the mast may be modular including a mechanism to detach from and reattach to the basket at the user's will. When detached, the mast becomes a hand-held hitting system.

An inflatable portable ledge apparatus comprises an inflatable platform having a plurality of transverse baffles and a plurality of longitudinal baffles. There are a plurality of suspension straps connected to the inflatable platform. The suspension straps are connected the inflatable platform so that a load on the inflatable platform is distributed across all the suspension straps when the portable ledge apparatus is anchored at a single point.
