It's absolute hell, but it's over quickly). Day three is a rest day.

Actually, I do the sprints, then the run, then the day off. For whatever reason, I have great runs the days after I do the sprints. They seem effortless, and I'm not a great runner by any stretch. I would thoroughly encourage anyone to try it and tell me what you think.

The sprints are designed to increase natural HGH production by something like 500%. After doing them last year, I believe it. I gained noticeable muscle after a couple of weeks, and I literally started getting acne...including on my back like you see some juicers get. It wasn't terrible, but I felt like I was in high school again...sex drive went WAY up, too.

I have a friend who runs a lot, he does a similar thing. I'm gonna give it a shot
