I gave a clinic in Vancouver, British Columbia a few years ago covering a wide range of running issues.  As I went out for a run, the next speaker took the runners to the gym and demonstrated 20+ weight exercises that he felt were important for runners.  The speaker didn't see me re-enter the room as he took his first question: "Jeff Galloway said that we only needed to do two strength exercises for running, and you have shown us at least 20 exercises – who is right?"  The muscled guy glared at the questioner and said "Quite honestly, I don't want to look like Jeff Galloway."
