The old school bodybuilders ate a lot of meat and raw eggs. Bodybuilders these days eat absolute junk. They are on drugs.

old school bodybuilders were much smaller. Arnold was only about 250 lbs @ 6'2" while modern bodybuilders are about 320 lbs @ 5'10"
Arnold was also on steroids. of course modern bodybuilders use a lot more drugs than just steroids.
