Stand tall with your feet hip-width apart. Bend both knees, swing arms back, and drive off ground as high as possible. Land softly and immediately bend your knees, place hands on the floor in front of you, and jump your feet all the way back so you end up in a plank position. Lower your chest to perform a pushup. Jump both feet back in and stand. Immediately jump up to repeat. Continue to do as many reps as possible for 30 seconds.
