haven't read all umpty-ump pages of dialogue, but here's my 2c: i was doing bodybuilding for a few years a while back and while i did enjoy it a lot, i *vastly* prefer powerlifting for one simple reason:
with bodybuilding, you train and train and train and in a few weeks or a couple months, you check to see if it's working.
with powerlifting, it goes up - it worked, on to the next goal. it didn't go up - need to work harder.
me, i'm all about instant gratification, lol.
