Hard to stay motivated if you are only getting around 20% functional carryover from machines (number I got from a PT but I don't know where he got it from). Even if they did gain lean muscle in a way that was balanced, and worked hard enough to get results, they will still stumble the first time then try to walk on a curb, or anything else in life. I like the positive reinforcement I get from being more functional, 24/7, as an added motivation.
I would suggest very heavy dripping sarcasm, since it's not on THIS forum.
