That was the last running program I ever did (though I've been considering getting back on a sprinting program).
And yeah, basically a quick HIIT program for the treadmill.
Did your quads develop really quickly when you did it? Mine are really getting big quickly. I wish the rest of my body was seeing results like this. In three months of distance running and cross-fit, my legs didn't do shit compared to a few weeks of sprints.
