Using a combination of jump rope, resistance band and boxing fitness instruments, one can get a robust anaerobic and aerobic exercise experience. However, traditional jump rope equipment requires the operator to be in a location that has ample height and space around them to accommodate the range of the rope being swung around the body. In addition, the ground surface that a traditional jump rope would be hitting may not always be ideal such as carpet, sand, and the like which diminishes the rhythm of the workout. The single unit multi-purpose jump fitness, boxing training and resistance strength device described herein eliminates the need for most of these restrictive considerations as there is no “rope” to jump over when in jump rope workout mode. Rather, the operator swings two specialized end handle units in a “jump rope” fashion while holding adjustable jump handles.

Provided is an air sensor, coupled to an air inlet of an air-filled product that is filled with air to maintain a shape thereof, the air sensor including: a connector coupled to the air inlet and communicated with an interior of the air-filled product, thereby allowing air in the air-filled product to be introduced into an interior of the connector; a silicon sensor provided inside the connector, thereby being operated by air pressure of the air-filled product; an impact sensor configured to detect an impact caused by an operation of the silicon sensor; and a PCB connected to the impact sensor, thereby displaying the number of times according to a detection signal of the impact sensor.

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.

Provided is a skipping rope. The skipping rope allows the rope skipping times being counted and displayed in the form of light, facilitating users and others to learn about the rope skipping times. The skipping rope comprises two handles, a rope arranged between the two handles, a counting module located on one of the two handles for counting the rope skipping times, a display device arranged within the rope and electrically connected with the counting module for displaying the rope skipping times in the form of light after the counting module counts the rope skipping times.

A portable exercise device with a cylindrical and elongated main shaft and a plurality of central components that fit over the main shaft. Both ends of the main shaft are releasably attached handles. Each of the handles comprises a grip section that is cylindrical in shape and overlies a handle support. The grip section of each of the handles is releasably attached to the handle support, and the handle supports are releasably attached to the main shaft. Longitudinal axes of the main shaft and handles are collinear. Each of the handles comprises an attachment member that extends from a distal end of the handle and forms an arc. An inner circumference of the attachment member is circular except for a flat portion that is equal in width to the flat portion of the handle support. The handle attachment members are configured to releasably attach to the handle supports.

Disclosed herein are training devices having at least two elastic members connected to a respective end of an inelastic member. The training devices first and second handles coupled to a respective one of the two elastic members. The training devices may be used to add various strength training modalities to a cardiovascular workout or fitness regimen. The training device 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.
