Not just realistic, but almost exactly what I did.
I’m about your height, started at your weight, and met your goals fairly quickly with regular training and eating.
Make sure you eat though. When I wasn’t eating enough, I wasn’t gaining weight, and that limited my strength gains. Eating enough is STILL a problem for me, so don’t slow your progress by not eating enough.
I haven’t been in the weightroom more than once or twice since this post. Great.
My diet is still what I like to call SHIT.
Still skinny, but getting bigger…
That’s two more months of your life you wasted not getting one step closer to something you claim to want to do that you’ll never get back. If you really want to get it done get an attitude about it and go to work or else stop taking up space here. People are watching you from their rear view mirrors in terms of progress as you decide “alright this is IT!, well after next weekend or the diet starts tomorrow, tonight is taco night!” or whatever you say to yourself. If I was you I wouldn’t make one more post on this website until you prove to yourself that you are willing to do what it takes to make some significant progress in this game.
