A portable cocking practice device according to an embodiment of the present invention comprises: a first shaft part having a hollow therein and having an opening at one end thereof, which is connected to the hollow; a second shaft part inserted and fixed into the hollow of the first shaft part through the opening of the first shaft part over the entire length or a part of the length thereof; and an rod withdrawing part received inside the second shaft part so as to withdraw a given rod out of the second shaft part by an uncocking operation of a golf swing, thereby improving a user's convenience and portability while increasing similarity to the actual golf swing and enabling a cocking practice according to each golf club.

A training bat assembly for improving a user's swing of a baseball bat is provided. In one embodiment, the assembly includes a bat portion and a plug or cap portion, where the plug or cap portion is configured to mate with a distal end of the bat portion. For example, the bat may include a circular opening, and the plug may include a circular rod that is configured to fit within the opening. Alternatively, a cap with a circular opening can be used, where the cap is configured to fit over a distal end of the bat. By mating the plug or cap with the bat, and swinging the bat from a first position to a second position, the plug or cap is propelled from the bat, where the resulting location of the plug or cap can be used to determine the correctness of the user's swing was.

A golf swing trainer apparatus for straightening or otherwise improving a golf swing. The golf swing trainer may include a rod, a handle connected on one end of the rod, a bulb disposed on the other end of the rod, and a magnetic base positioned in the middle of the rod. An impact sliding block may be constrained to move on the rod between the bulb and the magnetic base, and may be held in a rest position by the magnetic base. When the user makes a stroke with the trainer apparatus, the impact sliding block may be forced downward from the magnetic base and may impact the bulb, making a sound to provide the user with feedback about their golf swing.

In general, an exercise device includes a handle having a first end and a second end. A curved member is coupled to the first end of the handle. A movable member is coupled to the curved member, with the movable member configured to travel along a length of the curved member, where the movable member has a first portion and a second portion, and the second portion is configured to move relative to the first portion. An elongate member has a first end and a second end, and the first end of the elongate member is coupled to the second portion of the movable member. A weight is coupled to the second end of the elongate member.

An exercise device for a person exercising on a support surface includes an elongated bar having two opposed ends. A weight has an aperture therethrough and slides along the bar. At least two rigid weight stops are fixed with the bar at selected locations along the bar, the weight free to slide along the bar therebetween. An end caps may be fixed to each end of the cylindrical bar to capture the weight and any weight stops on the cylindrical bar. In use, with the weight slidably captured on the bar, and at least two of the weight stops fixed with the bar on opposing sides of the weight, the person exercises by moving the bar to slide the weight between the at least two weight stops, or by rolling the weight along the support surface while holding on the cylindrical bar in a sit-up style position.

An athletic swing trainer permits an athlete to swing a trainer at speeds far in excess of the athlete's conventional swing speeds and to confirm to the athlete that the practice swings made with the trainer at these extremely high speeds have been technically properly executed. Armed with this experience, the athlete is then able to swing the athlete's own conventional club, bat or racquet at speeds which, though lower than the athlete's trainer swing speeds, are significantly higher than the athlete's conventional club swing speeds. After six or seven trainer swings, an athlete's swing speed at point of contact of a conventional golf club, bat or racquet with a corresponding ball is typically increased in a range of 5 to 15%.

A training device and method for teaching a user the proper execution of various elements of an athletic swing. The swing training device incorporates a sliding member that simulates the impact of striking an object providing audible, visual and tactile feedback to the user pertaining to the proper execution of the swing, and displaces a force capture member a distance proportional to the force generated by the swing, and maintains this position until reset by the user. This allows the swing training device to quantify the force generated by the swing at the critical moment of impact. Further, the swing training device incorporates a movable stop that allows the device to be configured to provide for training methods that focus on the proper execution of specific swing elements, and it provides a means of quickly resetting the device for the execution of subsequent swing, thus maximizing training time.

A golf training device having a proximal stop a distal stop and a free moving weight. When a proper swing is used by the device the weight will remain against the first stop through the majority of the swing's arch, and not contact the second distal stop until the bottom of the arch, where the club would strike the ball. A golf club having such a training device integral with the club or removably associated with the club.

Proposed herein is a golf swing training apparatus for providing sensations of hitting for golf swing practice. The golf swing training apparatus includes: a shaft body formed to a predetermined length, and having a grip; an impact ball coupled to be movable along the longitudinal direction of the shaft body, and configured to provide weight; a ball rail formed along the longitudinal direction of the shaft body, configured to provide a movement path, and provided with a stopper; one or more magnets installed in the impact ball, and configured to provide a magnetic force; and a magnet fixing part configured to face the magnet while forming a metal region, and also configured to hold the impact ball through the action of attraction with the magnet and to provide an attractive force having a different strength depending on the position of the impact ball.

In general, an exercise device includes a handle having a first end and a second end. A curved member is coupled to the first end of the handle. A movable member is coupled to the curved member, with the movable member configured to travel along a length of the curved member, where the movable member has a first portion and a second portion, and the second portion is configured to move relative to the first portion. An elongate member has a first end and a second end, and the first end of the elongate member is coupled to the second portion of the movable member. A weight is coupled to the second end of the elongate member.
