A plurality of golf hole shapes (e.g., star, circle, rectangle, triangle and hexagon) with a ball reception area in the center of each shape, are set on a flat surface to whatever distance chosen by players. The holes are in various diameters and each shape has a different sized entry and point value. The shapes are a part of a putting skill game played by one or more players. Players roll the dice to determine the order of play--highest points to lowest ordering. During a players turn, he/she rolls both dice and putts at the shape indicated on the dice. If a player rolls a flag, they can shoot at any shape. Each player keeps score of the points earned when they hit a ball into a shape. The first player to score a predetermined number of points wins.

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 spiked ball marker connected to a rotating alignment component is provided. The ball marker is designed to prevent rule violations for compromising the golf ball location on the putting surface when marked. The alignment component is adjustable and moves while the connected spiked ball marker is not allowed to move at all. The spikes of the spiked ball marker penetrate the ground to prevent the ball marker from moving as the alignment component is adjusted. The alignment component provides a golfer the option of adjustment by use of a putter in order to gain visual perspective of the putting surface terrain while in the act of adjusting the alignment component for the purpose of enhancing the accuracy of aiming towards a desired trajectory at the golf hole.

A portable magnification angle adjuster for golf putting is proposed. More particularly, in the portable magnification angle adjuster for golf putting, the decrease of the beauty and portability of the magnification angle adjuster due to the protruding of the knob from the casing during the rotation of a knob for the rectilinear movement of a rotation weight is prevented, and the range of the engagement of threads formed to move the rotation weight is limited such that the moving distance of the rotation weight is limited. To this end, the portable magnification angle adjuster includes: a casing; an indication hand; a knob; and a dial; and a rotation weight.

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 system and process for training a user's sports swing to maintain arm position and body rotation so as to promote a proper swing arc. The system includes a waist wrap having one or more attachment area on an outer surface. The system also includes one or more training blocks configured for attachment to the attachment area depending upon the type of swing being practices. The process promotes a proper swing arc by indicating incorrect arm position and/or body rotation through excessive contact between the user's arms and the training blocks during the swing. The goal of the system and process is to train a user's muscle memory for the correct arm position and body rotation in a proper swing arc.

Novel tools and techniques for teaching a player the proper alignment when addressing a golf ball. In one aspect, such tools and techniques provide an alignment aid that allows the player to visualize both the intended target line of the shot as well as the position of the ball relative to the player's stance, allowing the player to easily modify his stance to obtain the proper alignment.

A training aid stimulator for providing fast perceptive feedback is provided. The training aid stimulator includes a first skin electrode for making electrical contact to the body of a user and a second skin electrode for making electrical contact to the body of a user. A body capacitance charging module is connected to the first skin electrode and a discharge module is connected to the second skin electrode for a feedback discharging of a body capacitance. A processor is connected to the body capacitance charging module for controlling the charging of a body capacitance to a predetermined first voltage level, wherein the processor is connected to the discharge module for controlling a feedback discharge of the body capacitance. The stimulator further comprises a measurement module for measuring the level of charge of the body capacitance.

A shoulder rotation clip as a putting trainer to assist a golfer in repetitive drills to improve the skills necessary to strike a golf ball in a straight manner and drop the ball into the hole on a putting green. The shoulder rotation clip is used in conjunction with existing alignment rods to prevent twisting of the wrists and arms to improve a golfer's putting stroke.

A putt ruler is a device that separates the skills of straight-line putting from reading the green. The putt ruler may be affixed to the golf green and may be rotated to align with the identified target line. Through placement of two golf balls atop the putt ruler, a golfer may produce a putt that follows a straight line, when the stroke used may not have produced a straight-line putt on a single golf ball. The golfer may then evaluate the chosen target line in relation to the resultant putt and evaluate the speed of the putt as the ball travels along the playing surface.
