I know that runners occasionally talk about "hitting a wall." This usually means a sudden loss of energy. Yesterday, I "hit the wall" while jogging on my treadmill. I know I am in poor shape (right now), but this had nothing to do with my endurance. I literally hit the wall. Well, not quite.

I was about twenty minutes into my jog when the treadmill stopped abruptly. My chest hit the treadmill's console while my feet slipped on the running surface. Consequently, I have severe pains in my chest, hips, knees, and back. I only wished that it looked as funny as it sounded.
