Abstract: An exercise system may function as a jump-rope and a resistance band. The system includes an elastic elongate element such as an elastic rope, a first handle, and a second handle. The elastic elongate element includes a first end, a second end opposite the first end, and a first rest length extending between the first end and the second end. The first handle is arranged at the first end and is configured to engage the first end of the elastic elongate element. The second handle is arranged at the second end and is configured to engage the second end of the elastic elongate element. The system is configured to achieve a first configuration, wherein the first handle and the second handle are arranged in-line with the elastic elongate element, and a second configuration, wherein the first handle and the second handle are arranged transverse to the elastic elongate element.
