Yeah, but the look on the instructor's face when you pass out is priceless.

Actually it was just her look when I went for my inhalor. I was smart enough to release the tension. Now if she could grasp the concept that the worst thing is to *just stop*. Once my breathing was under control, I was there pushing myself again.

Sorry for the heavy breathing, pant pant pant.

But I learned, and despite what the instructor says, I control the tension knob.
