Abstract: An audio-based repetition counter system and method are disclosed. In some embodiments, the audio-based repetition sound counter system includes a computing device connected to a microphone. The computing device includes a processor and one or more memory devices, and a repetition counter module is stored on the memory device and executed by the processor. The repetition counter module processes audio data received from a microphone and provide a number of repetitions for one or more series of one or more activities; for example, jumping rope. Further, an audio-based method of counting repetitions for a physical activity is provided.

Abstract: A jump rope device includes a connection assembly having a male connecting member and a female connecting member. The male connecting member includes a head having at least one locking projection. The female connecting member defines an opening configured to receive at least a portion of the male connecting member into an internal cavity. The female connecting member includes at least one locking arm that is biased into a first position, and configured to move from the first position into a second position when the male connecting member is inserted into the opening. The at least one locking arm is configured to return to the first position following insertion of the male connecting member to thereby create a secure connection between male and female connecting members.

Abstract: Jump rope devices which allow for the quick and easy interchanging of a cable of varying weight and length from handles configured to provide smooth rotation of such cables at both low and high speeds are disclosed. Devices in accordance with the disclosure may comprise a ball bearing assembly configured to facilitate 360-degree rotation of the cable. In an aspect, the handle of such jump rope devices is comprised of a ball bearing portion which enables both speed of rotational movement for a plurality of relatively lighter cables, and strength and durability for a plurality of relatively heavier cables. Handles may further comprise a snap hook assembly configured to facilitate rapid interchanging of cables.
