Oy.

Well, I made it through about three weeks of working out before doing something overly enthusiastic. That has to count for something, right?

In case you were wondering, interval training (alternating between sprinting and walking) may be great for fat loss, but it also kicks your ass six ways from Sunday. And should you decide to give it a shot, I recommend starting out with, oh, twenty minutes of it. Not half an hour.

If you need me, I'll be on the floor, moaning and feeling sorry for myself.
