Then there is the safety factor. Those who don't have the assistance of spotters never push themselves hard enough with free weights in some exercises. Look at the bench press. People stop far short of fatigue in that exercise because they don't want a big weight stuck on their chests. No such problem with a good quality bench press machine.
