Life is complicated.
This workout isn't.
This workout uses simple, basic moves. It requires no equipment, not even a timer. There are 3 marching breaks allowing you to catch your breath so you can work harder during the working phases. For butt kickers, high knees, and marches, count each time the right foot touches the floor.
On your mark. Get set. Go.
