In one example in accordance with the present disclosure, a jump rope handle assembly is described. The jump rope handle assembly includes a handle having a longitudinal axis. A shaft assembly is disposed within the handle. The shaft assembly is to receive a jump rope section and is to rotate and slide within the handle. The shaft assembly includes a collet to retain the jump rope section. The jump rope handle assembly also includes a spring to compress between the shaft assembly and an interior impact surface of the handle.

The present invention is a group workout program that allows instructors to lead and teach multiple exercisers machine, free weight and other forms of exercise simultaneously. Participants within a single exercise area can do the same free weight, machine and accompanying exercises simultaneously. They can also circuit train in small, medium and large circuits doing the same or different exercises concurrently or simultaneously under the direction of an instructor. More than one exerciser can exercise on each machine at the same time and machines can be combined to deliver more exercises. An exerciser can do multiple exercises on a single machine either changing the configuration between exercises and also by leaving the configuration the same and simply moving between varying exercises. The workout program allows an instructor to teach exercises and exercise combinations in way where they can have a slow, medium, fast and mixed pace. The workout program method can be conducted simultaneously for participants of different fitness levels and experience and can be delivered for specific body parts or entire body workout programs.

A platform models and correlates physical activities based on users' interactions with a simple grip-metaphor design, enabling multi-dimensions actionable information to improve the health, performance and well-being of connected grip users within like-minded communities. For example, the platform captures multi-dimensional datasets generated from activities of each of a plurality of users on the online human internet of thing platform, where the activities include physical interactions with connected grips systems connected to the online human internet of thing platform. The platform then filters the captured multi-dimensional datasets into a plurality of categories and scores the filtered multi-dimensional data by the human internet of thing platform. Finally, the platform generates a multi-dimensional information modeling for each user based on the scored multi-dimensional data.

A system includes a handle with a hinge mechanism at a first end, the hinge mechanism including a lower hinge portion and an upper hinge portion rotatably coupled together. The handle also includes a rotary mechanism positioned at the first end and coupled to the lower hinge portion to enable circumferential movement of the lower end portion about a longitudinal axis of the handle. Additionally, a sensor arrangement is positioned within a body of the handle, the sensor arrangement measuring a number of rotations of the rotary mechanism about the longitudinal axis of the handle.

A mechanical jump rope device for forward rotation of the rope with backward rotation obstructed by a ratchet and pawl mechanism includes a semicircular rope having a pair of ends. Each of the ends is coupled to a respective one of each handle of a pair of handles. Each of the ends of the rope engages by a ratchet and pawl mechanism with each of the handles. A distal end of each of the handles engages by a push button locking mechanism to a bar. Each of the handles can be attached or removed from the bar. The user can use the mechanical jump rope device with or without the bar. The rope rotates forward and the user jumps over the rope. Backward rotation of the rope is hindered by the ratchet and pawl mechanism.

An exercise system includes a handle having a shaft, a head, a spindle, and a loop. The shaft extends from a first end to a second end. The head has a top, a bottom, a front, and a rear, the top opposite the bottom, the front opposite the rear, the bottom of the head affixed to the second end of the shaft. The spindle has a ring and is positioned at the front of the head with the spindle rotatably supported upon the head. The loop is affixed to the top of the head. The exercise system includes one or more elastic exercise cords configured to selectively connect to the loop or the ring. The exercise system may include one or more kettleballs configured to selectively connect to the one or more elastic exercise cords. The kettleballs and/or elastic exercise cords may be moved in a circular motion.
