Prediction?......Pain.

No pain, no gain.

Myth?

Well, to some degree yes. It really boils down to what your personal definition of "pain" is. Personally I have pretty high pain threshold, probably due to a childhood of chronic migraines. That sort of conditioned me to have a thick skin.

When you are working out hard you will have some discomfort. However, it is not necessary to feel legitimate pain while you exercise. In fact if you are feeling pain pain, you should stop and let your body heal.

Just to clarify my view, I don't think of a muscle burn as pain. Sure, it doesn't feel good and you want it to stop, but it's not pain. A blown out knee is pain, a severe migraine is pain, child birth is pain. Doing one more pushup when your body is burning is not pain.

Don't feel like you must suffer to get results from exercise. You'll get uncomfortable, maybe even a little sore, but you don't need to be in agony. If you feel any sharp, stabbing, or dull, persistent pain stop and go get yourself checked out.

So no pain, no gain? Well, maybe for you sissies out there, but for everyone else, I don't think so.

Train smart,
