> Size? Strength? For what functional purpose? It's vanity.
Vanity doesn't come from strength, size, beauty or health, or any objective factor in your body . It comes from your own pride about yourself and your own desire to belittle others or put them down using your status.
Think about prayer: a person can pray for 3 hours at home and not do it in vanity, or he can pray for 3minutes in public and be totally vain about it. Same goes for lifting or anything. Its not the thing itself, its how you relate to it that makes you vain.
So your fear that lifting more than 3hours per week "is vanity" is totally misplaced. It doesn't work like that.
>id be interested to hear if there is any evidence that hardcore bodybuilders live longer or are less prone to disease than people who do moderate light
doubtful because bodybuilding at the "hardcore" level is extreme and requires sacrifice.
But studies show that heavy lifting itself is extremely beneficial for ligament, bone, and muscular longevity, so you don't become frail and prone to injuries when you are older. Yes heavy lifting, not "light" exercise. Tons of studies on it, if you just google.
3 hours per week is a minimum, it really is only effective if your sessions are extremely intense.
