However is a physique like that worth it.
Just because Coleman can do Leg Presses of a tonne +, doesn't mean he should. He's using so much Steroid, and Growth Hormones, making it past 60 years, could be the biggest achievement in his life, not multiple Mr O titles, and a Tonne Plus on Leg Presses.
I rememeber a guy on a board I used to go on, that's know defunked, who was about 220lbs used, and got to about 40 years old, and had to stop the Steroids. Not through choice, but he was lifting so much weight on Delt exercises, it had shot his Rotator Cuffs to bits.
So realistically he was going to eat hard, train a bit lighter, and take some quality supplements, possibly Promhormones and maybe products like 6-oxo, that are often used between cycles, though I'm not terribly au fai with products like that.
Well there are natural organisations with strict testing, so some people can do those if they're naturals.
