A method performed in a computer-implemented platform includes obtaining sensor data from sensors embedded in a first grip and a second grip of an item of fitness equipment while a user exercises using the item of fitness equipment. The user interacts with the first grip and the second grip while exercising using the item of fitness equipment. The method also includes analyzing the sensor data to determine differences in performance between the left side of the user's body and the right side of the user's body and providing personalized activity for the user to compensate for the differences.

A fitness tool is described. The tool includes a grip component and a handle component. The handle component includes sensors and the grip component includes an electronics unit. The electronics unit includes a fitness application. The fitness application receives a signal from a button located on the grip component to signal that the user is performing an exercise. The fitness application also receives a measurement of force applied to the handle component from the sensors. The fitness application processes the signal and the measurement of force and then transmits the signal, the measurement of force, and other exercise metrics to a computing device. The user interacts with another application on the computing device to view, track, and modify these exercise metrics.

Training devices having at least two elastic members are respectively connected to opposing ends of an inelastic member. The training devices have first and second handles coupled to a respective one of the at least two elastic members. The training devices may be used to add various strength training modalities to a cardiovascular workout or fitness regimen. The training devices may be provided in the form of a kit including elastic and inelastic members having differing elasticities, lengths, and widths and including removable handles, potentially of differing types.

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.

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.
