Abstract: An apparatus for providing wrist angle feedback to a user is disclosed, the apparatus including an arm cuff having a front end, a back end, a top face, and a bottom face shaped to engage the user's forearm, and a dorsal interface module hingedly coupled to the arm cuff so its distal end pivots relative to the front end while contacting the backside of the user's hand. A feedback element disposed within the dorsal interface module is configured to deliver feedback, such as auditory and/or haptic, whenever the dorsal interface module rotates toward the arm cuff, thereby giving the user immediate, repeatable cues at a predetermined wrist-extension threshold to help train optimal wrist angles, enhance swing mechanics, improve consistency, and reduce injury risk.

Abstract: A slope estimator training apparatus has an apparatus body with a top surface having one or more sloped surfaces. A center segment extends across an apparatus periphery of the apparatus body and partitions the apparatus body into a first section and a second section. Each of the first and second section have a sloped surface. The slope estimator training apparatus further includes slope markings disposed on the top surface at each of the first section and the second section. The slope markings include a range of values having both a descending sequence and an ascending sequence. The descending sequence is disposed on the first section and the ascending sequence disposed on the second section. The slope estimator training apparatus allows a player to train their skill in estimating steepness of a slope with a feel of their feet instead of or in addition to making a visual assessment.

Abstract: A golf swing force shift indicator with a trail foot support includes both monolithic and detachable configurations to provide increased leverage and support to a golfer's trail foot during use of the golf swing force shift indicator. The golf swing force shift indicator includes a top face and a bottom face opposite the top face. The top face is where the golfer places their lead foot near a front face. The bottom face is configured to have various angular orientations during a golf swing. The trail foot support is disposed at a rear face opposite the front face. The trail foot support forms an upward incline relative to the top face where the golfer can place their trail foot on the trial foot support.

Abstract: A golf training device is provided including a base plate having a putting channel. The device may also include a calibration plate having a calibration channel, a ball gate including first and second ball gate posts and/or a putter gate including first and second putter gate posts. The calibration plate is selectively attachable to the base plate with the calibration channel overlaying the putting channel. The ball gate has an adjustable ball gate width sufficient to allow a standard golf ball to pass therethrough and the putter gate has an adjustable putter gate width sufficient to allow a head of a putter to pass therethrough. The ball and putter gate widths are adjusted by rotating the first and/or second ball gate posts and the first and/or second putter gate posts, respectively.
