Abstract: An exercise system comprising a clamp for securing or engaging a dumbbell. The system may include a cable connector and the clamp. The cable connector includes an aperture that is configured to engage a corresponding attachment of a cable. The clamp has an open configuration and a closed configuration. The clamp defines a first cavity and a second cavity. When the clamp is in the open configuration, the first cavity is configured to receive a portion of exercise equipment and the second cavity is configured to receive a portion of the cable connector. When the clamp is in a closed configuration, the clamp is configured to secure the cable connector relative to the exercise equipment.

Abstract: A shoe includes a base and an upper. The base is configured to contact a ground and includes a groove. The upper is configured to extend over a foot of a user. The upper includes a rail configured to be inserted into the groove to connect the upper to the base. The groove and the rail cooperatively form a detent that is configured to selectively inhibit relative movement between the rail and the groove when the rail is fully inserted into the groove.
