A basketball shooting training device includes a main frame, a first vertical rail structure having vertical and oblique rails, a first sliding base, and a first basketball imitation member. The first vertical rail structure is disposed on the main frame. The first sliding base is slidably disposed on the first vertical rail structure for sliding along the first vertical rail structure. The first basketball imitation member is connected to the first sliding base. When the first basketball imitation member is propped and then propelled upwardly by a user's hand, the first sliding base slides from a first initial position on the vertical rail to a shooting position on the oblique rail for guiding the user's hand to complete a set shot along the first vertical rail structure.

An apparatus and system for obtaining metrics associated with a user's athleticism are disclosed. The user performs a workout using the apparatus, and the workout is scored based on a scoring system. The scoring system may be objective, thereby facilitating score standardization, and individual users for which scores have been recorded may be ranked by the system. Individual users may associate their system profiles with one or more positions for one or more sports. The rankings may be filtered by position and sport to facilitate identification of one or more users of interest, such as for a college recruiting purposes or professional sports team drafts.

A strike training attachment for a heavy bag may include a ball member sized according to the diameter of a typical adult human fist. The ball member may be resilient. The strike training attachment includes a loop member disposed on an outer surface of the ball member. The loop member may be attachably co-operable with a hang-mounting member of a heavy bag.

A toy having three bobs on a string where the middle bob slides. A low moment of inertia of the middle bob is desirable because it minimizes tangling of the string about the middle bob and produces smooth, tactile-appealing orbits. Each bob has a pair of mated throughbore pieces sandwiching a central metal weight and an equatorial bag stuffed with low-density pellets. Concave sections (in profile on a plane along the polar axis) of the throughbore occupy a substantial portion of the length of the throughbore to take best advantage of the torques produced by the string by focusing the tension of the string at the mouths of the throughbore. The concave sections also reduce the volume occupied by the bag, thereby reducing moment of inertia. Additionally, hollows in the concave regions of the throughbore pieces further reduce the moment of inertia.

A resilient exercise article includes an outer surface defining an interior chamber. The article comprises outward being one of a spherical shape, an ovoid shape or a double ovoid shape, at least one circumferential groove defined in the outer surface, and a bore extending axially through the article.

A training system includes apparel and balls that fasten to the apparel. The apparel includes patches or strips of hook/loop fastener material that couples to strips of the hook/loop fastener material on the balls. The balls are removed during training by an opponent. The balls are placed on the apparel to emphasize training to that region.

An apparatus for assisting and improving baseball hitting is described. The apparatus includes a spherical object having an interior anchor and a cord extending therefrom. An adjustable mass body is disposed within the spherical object along the cord. The interior anchor allows the spherical object to rotate about the cord.

The objective of the present invention is to provide a stability ball case configured to store a stability ball therein and, especially, having a weight thereon to prevent the stored stability ball from rolling, thereby avoiding a safety accident that may happen when the stability ball rolls and drops, as well as storing the stability ball at a desired place in a safe and convenient manner. particularly, another objective of the present invention is to provide a stability ball case configured such that a weight can be attached to and detached from a body constituting the case, whereby the weight can be separated from the body when the case is washed, or when the stability ball is carried, thereby enabling the stability ball case to be safely used and stored, as well as being conveniently used.

A launching and/or catching toy kit has a ball and at least one associated slingshot. The ball includes a spherical body, a support non-movably attached to the body, a tail, a first and a second elastic band hook oppositely disposed. The slingshot is configured to launch the ball from a first user to a second user. The slingshot includes a handle and a pair of prongs connected and/or extending from the handle top. At least one elastic band is connected to each prong. Each of the at least one elastic bands are releasably captured by their respective first or second elastic band hook on the football during launching by the first user. When two slingshots are available, the users can shoot and catch the ball between each other allowing for a game of catch.
