The burpee is a versatile movement. In its simplest form, it requires little skill, space, or equipment. However, the framework of the basic movement lends itself to many creative variations, such as burpee box jump-overs, which have the potential for greater intensity and challenge coordination, agility, and balance. 

"Double-unders require the athlete to propel the body upward and lift the feet up to several inches from the ground while making small, fast circular movements with the wrists in order to execute multiple turns of the rope with each jump. They develop dynamic balance, speed, quickness, agility, coordination, concentration, and cardiorespiratory efficiency." —Buddy Lee, "Jump Rope Basics, Part 2" (adapted)

As an example of high functionality and marked carryover of cardiorespiratory benefit to sport and human performance in general, we offer our “wallball” exercise. This exercise is largely a front squat and push-press combination. The functionality of throwing or shooting an object from overhead and standing up is hopefully obvious.
