No I didn't. The guy who I look up to is at least 100kg. Nowadays he may be closer to 110kg (i don't ask him his weight routinely) because he just keeps getting bigger. He is a monster.
But normal is within the 90-95kg range for guys of my height. At 85kg, you are considered pretty skinny.
Not knocking you, perhaps your gym is different to mine. All I know is those are my stats, and they're mocked in my gym (in an encouraging way, not a harsh way).
Everyone around the 5ft 9in range should be aiming to get up to a lean 100kg anyway. Not everyone will make it, but you gotta set goals. You know you're a real man when you break through the 100kg barrier, lol.
There is an easy way to know your ideal bodyweight (as a bodybuilder): it is when your BMI reads 'morbidly obese' but you actually have a 6-pack.
