I think many people focus too much on how much weight they can lift instead of focusing on getting in shape. I see a lot people bench pressing 350+ lbs but look completely out of shape (big belly). Also most of those who list heavy weight can not do pull ups more than 10. I am 5-11, 180 and 42 years old. I use ~200 lbs for bench press which is not a lot but can easily do 25 pull ups, or 70 push ups once warm up.
I guess people have different goals.
