I’d kill to look like that but I assume drugs are involved.
Also I’m 35 and waaaaay out of shape (like walking up stairs or fairly short distance gives me sore muscles the next day lol and im over 350 lbs of almost all fat) so idk if like the timeline age wise would be bad.
I started when I was ~22 or so, but I went from ~320 to ~180 and 14-18% bodyfat and have been able to maintain that for about 15 years now without any supplementation (I’ve even been vegan for the last 10 years or so lol). So I would have to guess that your target is attainable.
As far as timeline, I lost the bulk (~100lbs) of the, well, bulk in about a year, but I was in a position where I could really focus on that goal. But still, even if you double that, 37 isn’t that old right?
I can provide more details if it would be helpful or people are interested. But I just wanted to say that, at least from my sample size of one, you should go for it
