A target device for improving a user's aim includes a base, a magnet and a rotatable target rod having a reset end member. The target device has a first state wherein the reset end member is releasably held in place by the magnet.

Various embodiments for a golf putting training aid having a first stake coupled to a second stake by an upper alignment string and a lower alignment string that collectively establish parallel reference putting lines when the first and second stakes are deployed around a putting surface to train a golfer to properly align their eyes when executing a putt are disclosed.

A golf training aid maintains alignment of a user's vision with an orientation line during a golf swing. The golf training aid has a stand configured to be securely positioned on the ground, a front indicator, and a rear indicator offset from the front indicator. The front indicator may be pivotally adjusted to move in synchronization with the rear indicator. The front indicator may have a first vertical element and a first horizontal element. The rear indicator may have a second vertical element and a second horizontal element. The user aligns the elements of the front indicator and the rear indicator to align the orientation line with the user's line of sight. Alignment of the orientation line with the user's line of sight defines an angle of between 40° and 80° with the ground.

A green simulation apparatus may comprise a covering forming a configurable upper surface with a changeable contour and being flexible such that the covering is movable between a base condition in which the upper surface has a substantially planar configuration and a contoured condition in which the upper surface has a contoured configuration. The apparatus may also comprise a covering support assembly configured to support the covering in the base condition and the contoured condition.

An electronic tracking system for assisting a user in determining distances to landmarks and objects in a sporting environment includes a user tracking system for determining the location of a user, a heads up display for displaying information to the user, and a processor operable to communicate with the user tracking system and the heads up display. The heads up display is designed to be worn on the user's head, and to display an image within the user's field of view. The processor is programmed to determine a distance between the user's determined location and an object or a landmark on. This information is displayed via the heads up display as a numeric representation of the determined distance.

A practice alignment tool to align a golf ball and putter during practice. The alignment tool is useful for creating a repeatable/consistent aligned squared swing with all golf clubs. A preferred embodiment of the alignment tool has a substantially “L” shaped profile as well as strategically placed tee holes, notches, and markings that allow a golfer to align a golf shot to better hit a target during practice.

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.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

A golf putting training device for improving a putting stroke of a user includes a base that is positionable on a surface. A pair of posts is coupled by lower ends to the base. Each post is positioned proximate to a respective opposed side of the base so that the posts define a reference plane that is perpendicular to the base. A guide unit is engaged to and extends from the base in a guide plane that is parallel to the reference plane guides a shaft of a putter during a putting stroke. A constriction unit that is engaged to the posts and selectively positionable in abutment to outer faces of knees of a user prevents outward motion of the knees during the putting stroke. A stance governing unit that is engaged to upper ends of the posts templates a posture of the user during the putting stroke.

A hole cup for golf practice includes: a base plate with a given area unfoldedly located supportedly on a floor; and hole wall bodies arranged on top of the base plate to extend upward from the base plate to a given height and having an entry hole formed at the insides thereof to allow a golf ball to accommodatedly enter and entry openings formed on one side thereof to allow the golf ball to pass therethrough and thus enter the entry hole from the outside, wherein two or more entry openings are formed with different widths from one another.
