The disclosure is related to a method and a system for posture correction adapted to one sporting equipment. In the method, a force distribution history responsive to force or pressure data detected by one or more pressure sensors mounted on a surface of the sporting equipment over a period of time is firstly obtained. The pressure value is recorded in the force distribution history once it is detected that a pressure value exceeds a threshold, and the force distribution history is compared with a selected force pattern model so as to obtain a deviation distribution model. The deviation distribution model renders a correction data for the posture correction.

A lacrosse teaching device includes a body, a ball receptacle, and a valve. The body includes a first leg, a second leg, and an archway interconnecting the first and second legs. The body defines a tunnel and the archway defines an opening. A ball receptacle defines a cavity and an opening. The cavity is dimensioned to hold at least one lacrosse ball. The ball receptacle communicates with the opening in the archway such that a lacrosse ball can travel from the cavity of the ball receptacle through the opening in the archway and into the tunnel. The valve is positioned between the cavity of the ball receptacle and the opening in the archway and is actuable to control movement of the at least one lacrosse ball from the cavity of the ball receptacle into the opening in the archway.

A practice golf putter includes a body formed to hit a golf ball, the body having a concave portion, which is formed on the front of the body and is open at the front and on the top thereof. The concave portion includes inclined surfaces formed on the left and right sides thereof; and a protrusion formed at a lower end portion of a point at which the inclined surfaces meet, and protruding toward the front. Therefore, the golf putter has the following effects. Since a striking point can be known through the advancing trajectory of the golf ball when the golf ball is struck by a practice golf putter, the location of the practice golf putter can be changed as needed, thereby enabling correct swing stances to be mastered. Therefore, putting can be more quickly learned than when using a conventional technology.

An adjustable, easy to use, improved training apparatus for helping an individual hit a ball more correctly and fundamentally sound by improving said individuals posture and hitting position through use of the training apparatus.

A golf swing training apparatus comprising: a first attachment means; a first cord with a first end and a second end, the first end of the first cord attached to the first attachment means; a bite piece attached to the second end of the first cord; a first releasable connector attached to the second end of the first cord; a second releasable connector configured to releasably attach to the first releasable connector; a second cord, with a first end and a second end, the first end of the second cord attached to the second releasable connector; a retractable and extendible cord attached to the second end of the second cord; a lockable retractor in operable communication with the retractable and extendible cord; a second attachment means attached to the lockable retractor. A method of using a golf swing training apparatus, the method comprising: attaching a first attachment means to a user's shirt; attaching a second attachment means to the user's waistband or belt; biting down on the bite piece; connecting a first releasable connector to a second releasable connector; adjusting the length of a first cord and a second cord so that golf swing training apparatus is at a proper tautness so that if the user's head moves excessively during a golf swing the first and second releasable connectors disconnect, thereby indicating to the user that his or her head moved too much; and practicing the user's golf swing.

A back support apparatus which includes a length of cloth consisting of a tail, body and buckle; the tail and buckle join to form a loop inside which a user sits. The apparatus and method of use stabilize a user in a seated position. The method of use is as follows: the cloth is wrapped around the users back and knees while in a seated, crossed leg position, and the tail threaded through the buckle and cinched tight in front of the users body. The apparatus is adjusted by pulling the tail further through the buckle, increasing support, or pulling the buckle away from the user's body, releasing tension.

A non-limiting example training instrument comprises a hollow main body formed of an aluminum alloy. The main body is constituted by two gripping portions opposite to each other with a space therebetween and a coupling portion coupling the two gripping portions. A load sensor is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.

A golf clothing for correcting a swing posture in golf sports is disclosed, which includes a clothing body (1) and an auxiliary structure for correcting swing posture provided on the clothing body, wherein: the auxiliary structure for correcting swing posture enables a player (5) to keep a shape formed by both arms and shoulders of the player as a triangular shape during a swing process. Through the auxiliary structure for correcting swing posture, the present invention is able to correct the swing posture of the player (5), especially the beginner, so that the player (5) is able to grasp the correct swing posture as soon as possible, thereby quickly improving the golf level and the sports experience.

A workout weight carrying bars, such a dumbbell or a barbell, that has an inclination sensor and display, to provide the inclination of the weight carrying device, which enables a user to monitor the position and balance and the workout device, in order to correct position, posture and balance, which yields better results from the workout, enhanced safety, and avoiding muscle and joint injuries caused by wrong movements and postures.

A body postural analysis and corrective exercise mat and mirror for utilization in a process of evaluating and correcting, through exercise, a user's posture, wherein the mat includes a planar surface that displays an analysis and exercise region that is delineated by a front border, a rear border, and two opposing side borders and a grid matrix formed onto the mat surface, wherein the grid matrix has foot placement markings employed by the user to establish a reference alignment position, a rear alignment block located near the rear border, and a central axis reference line with a plurality of mirror image reference bands that extend from near the front border to near the rear border.
