A hand weight includes a chassis including a handle portion configured to be grasped by a user such that a forearm of the user extends along an axis, and a flexible element attached to the chassis. The hand weight can be configured to receive a movable mass, and the flexible element can be configured to at least partially support the movable mass such that the movable mass forms at least part of a sprung mass of a hand weight assembly including the hand weight and the movable mass, the sprung mass configured to move relative to the chassis of the hand weight and deform the flexible element in response to a force in a direction along the axis applied to the handle portion by the user while grasping the handle portion.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

The invention relates to a golf training device.

Disclosed herein are devices, systems and methods for redistributing the normal weight distribution of a user in a standing position. One example is a postural platform for either the left or right foot having a bottom surface defining a reference plane, a top surface configured as a foot contact surface and a perimeter side wall between the bottom and top surfaces. The top surface is rotated about a first rotational axis parallel to the reference plane and rotated about a second rotational axis orthogonal to the reference plane. In another example, a system includes first and second postural platforms that are independent of one another. In other examples, the device is a sandal, shoe, sneaker or any foot covering with a tops surface being at a complex angle to a bottom surface.

A system for monitoring the symmetry of a lifting stance, the system including: a platform for supporting a weightlifter during a lift, the platform including support plates which include load sensors; a processor in data communication with the one or more load sensors for receiving and processing weightlifter load data, the processor configured to assess weightlifter symmetry data against a symmetry threshold to provide a symmetry result; and an output module for informing the weightlifter of the symmetry result. Also described is a method for monitoring the symmetry of a lifting stance, including the steps of: receiving data from one or more load sensors on one or more support plates on a weightlifting platform to process weightlifter load data; processing weightlifter load data to provide weightlifter symmetry data; assessing weightlifter symmetry data against a symmetry threshold to provide symmetry result data; and displaying the symmetry result data.

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.

Multiple embodiments of a portable, handheld exercise device comprise a spherical outer shell with multiple parallel handles on the outer surface thereof containing a rotating mass therein. An inner shell is spaced from but attached the outer shell. A gyroscopic energy-generating structure (GEGS) is within the inner shell. The GEGS comprises a rotating disc or a rotating mass simulating a rotating disc. The rotating disc or a mass is powered to spin around an axis orientated in a preselected orientation to the multiple parallel handles. When the one or more handles are held by an individual the spinning characteristics of the rotating disc or mass creates a force against the user's hands. An internal or external controller allows the user to vary the spinning characteristics of the spinning mass and the level and intensity of the resultant exercise provided to the user in counteracting the forces created.

Disclosed are implementations of a sensor enabled exercise slider configured to detect movement and applied force. A sensor enabled exercise slider is a limb-actuated, linearly and circularly moveable, apparatus configured to facilitate a variety of exercises. An example limb-actuated exercise slider comprises: a housing that is smoothly slidable across a contacted surface in contact with an undersurface of the housing; and an electronic circuit carried by the housing. The electronic circuit is configured to detect movement of the housing and to detect force applied to a top surface of the housing. In some implementations, the undersurface in contact with the contacted surface has a friction coefficient permitting the sliding.

The present disclosure relates to system and method for coordinating and providing overall feedback for one or more users performing one or more physical activities at one or more locations. The feedback may be generated as AI feedback or human feedback. The method involves data capturing and coordinating the physical activities of the multiple users. The information to be captured is regarding performance activity of the multiple users and processing the same information in real time using AI assisted model. The method includes comparing each user's activity performance data including various performance parameters having a set of target activity performance parameters. The method includes generating feedbacks based on the comparison of the performance parameters. The feedbacks generated are shared with the users and rendered on the multimedia output device available to the users. The method includes sending the feedback to external portals via corresponding Application Programming Interfaces (APIs).

A method for updating a treatment plan. The treatment plan is associated with a user using a treatment apparatus to perform the treatment plan. The method includes receiving first data associated with a first diagnosis of the user. The method includes generating, based on the first data, an initial treatment plan to be performed on the treatment apparatus by the user. The method includes receiving second data associated with a first attribute of the user. The method includes generating, via an artificial intelligence engine, a machine learning model trained to generate an updated treatment plan based on the initial treatment plan and the second data.
