Abstract: 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.
