>>21153621Brad Pitt in Fight Club is mostly just lean, but he doesn't have that much muscle.
Anyone can put on 10lbs of muscle in a year, and for a good number of people they can put on much more than that. 10lbs of muscle makes a fucking huge difference.
Combine that with weight loss, which you should also be doing as you lift weights and you can achieve a similar look to that in a year tops, less for most people.
Picture related is what one year of progress looks like for the average dude willing to put in the effort.
Unless you're one of those people who are absurdly skinny and cannot put on muscle, or you're simply obese this should be well within what you can achieve. People who are gifted with great genetics can do this in half the time if not less.
