One time, I did meet a "good person". He was a Powerlifter at my local Commercial Gym, ashamed of even being there. The guy was a good 325 pounds and training for 350 to hit one more competition at around 45 years. He thought me a lot more than I had learned in a year. Me, being an idiot, did not really memorize his name. He told me his name was Alex C. or something. Anyways, I just wanted to know what these terms meant because, well, who knows, one day I might need to fit under one.
