A training device can easily be affixed or mounted to the hitting face of a golf club. The training device may provide auditory, tactile, and directional feedback for the user during practice so that he/she may learn how to strike the ball consistently on the sweet spot. A training device may include several raised surfaces of varying shapes rising from the base surrounding an aperture centered over the sweet spot of the golf club and larger than the surface area contacted by the ball. Use of the training device may reduce the user's variance from the “sweet spot” due to a strike not only along the longitudinal axis but also along the vertical axis. The user avoids impingement with the raised surfaces of the training device by striking the ball within a pre-set tolerance as well as within the boundaries of the aperture.

A golf club head includes a body having a recessed channel formed in an outer surface. A weight assembly that includes a weight at least partially disposed within the recessed channel, a cover extending at least partially over the recessed channel, and a fastener coupling the cover to the body. The fastener is adapted to retain the weight in the recessed channel only indirectly by the cover. The weight is slidably engaged with the cover and the cover is positionable in at least an unlocked configuration whereby the cover is raised at least partially out of the recessed channel and the weight is selectively slidable within the recessed channel, and a locked configuration whereby the cover is at least partially disposed within the recessed channel and the weight is secured within the recessed channel. The weight moves with the cover between the unlocked configuration and the locked configuration.

A puck includes a cylinder having a curvilinear sidewall extending about and centered with a central longitudinal axis, and a plurality of sound emitting structures connected to the sidewall. At least one sound emitting structure is configured to emit sound when the puck rotates about the central longitudinal axis at or above a threshold rotational speed and translates at or above a threshold translational speed. The puck may include top and bottom surfaces having peripheral rims or flanges that extend beyond the periphery of the sidewall, thereby protecting the sound emitting structures from contact from a hockey stick blade.

An apparatus, kit, and method for rehabilitating and/or strengthening the soft tissues of a user's lower arm is disclosed. The apparatus has a first arm with a proximal end and a distal end; a second arm with a proximal end, a distal end, one or more discrete sections therebetween for engaging one or more weights, and a means for providing an audible feedback to the user upon completion of an exercise repetition or a half-repetition; and a hinge in contact with the proximal ends of the first and second arms. The hinge is configured to adjust the distance between the distal ends of the first and second arms, or the angle separating the first and second arms.

Provided is a golf training apparatus that helps a golfer learn a swing with trunk rotation and limited excessive arm movement, which includes an attachment member configured to be detachably attached to a pants belt loop on the front and right side of a user's waist, a case to which the attachment member is fixed, and first and second pads attached to the case via first and second string-like members, respectively. A force in a direction of winding up the first string-like member inside the case is constantly applied on the first string-like member, and the same applies to the second string-like member. The user executes a practice swing with the first and second pad sandwiched under the armpits. If the user opens an armpit, the first or second pad is pulled by the first or second string-like member and then returns to a region near the case.

A martial arts training system comprising: (a) one or more hand held targets; (b) one or more wearable devices; and (c) trainee log-in hardware installed in said target(s) and said wearable device(s).

A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

A running device and method of using the device are disclosed. The device may include a moveable material within an inner chamber of the running device's housing. In operation, a running device may be held in each hand and the runner may thrust both hands downward prior to landing and quickly bring the devices to a vertical stop after landing. Bringing the devices to a vertical stop may cause the moveable material to collide with the housing and increase the force exerted by the runner on the ground. A delay component may delay the peak force exerted by the material against the housing so that the translation of that force to the ground coincides with the peak force that the runner would have exerted against the ground in the absence of the devices.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.

In accordance with the present invention, there is provided various embodiments of a golf swing training device which is uniquely configured to maintain a desirable bent wrist condition through the entirety of the downswing (including golf ball impact) and follow-though or finish of the golf swing. More particularly, the training device constructed in accordance with the present invention allows the wearer/user to start the golf swing with the right wrist in its natural, generally flattened condition at address. Once the backswing of the golf stroke is initiated, the training device of the present invention allows the wearer/user to bend the right wrist back naturally, and at different amounts so as to represent the different amounts of right wrist bend a golfer may employ for shorter and longer strokes. Once the right wrist has achieved its full amount of bend at the time of the downswing, the training device constructed in accordance with the present invention effectively maintains such bend throughout the entirety of the downswing and follow-through or finish of the golf swing.
