An exercise grid includes four running strips and four crossing strips. Each running strip connects with each crossing strip at an intersection to form a grid. The running and crossing strips comprise firm rods positioned between pliable intersections. The firm rods positioned between pliable intersections facilitates folding of the grid at the intersections for transport. Placement of the grid on a playing surface allows one to perform various drills using the spaces between the running and crossing strips.
