HOMING IN ON THE SOURCE OF RUNNER’S HIGH. I’ve never experienced it, though I have started running again in a very mild way. I’m running a mile a couple of times a week, just for a change. Rippetoe is right that heavy lifting keeps you in good enough cardio shape that you can run a mile without getting winded. On the other hand — and this is one reason why I’m doing it — my form is terrible. I feel like a lumbering moose. I expect that will improve with practice.
