We are probably close to identical; I'm 25, 6'1'' and had never been heavier than 140lbs my entire life and have probably always lacked a ton of testosterone due to nearly zero physical activity but after a little more than a fucking month of doing all the basic stuff with a cheap set of bells, a barbell, pull-up bar with a bench attached, push-up+variations, and EATING A {{{SHIT TON}}} OF FOOD, I'm up to 145lbs. I feel better and happier than I ever have in my life. Also horny as fuck and wish I had started doing this before my gf left me :(

U can do it bro just go buy cheap weights, a pull up bar of some kind, and get through that first week of feeling like you can't do anything. After that week you'll discover that you can easily rip through reps and wish the days would pass faster so you can go again the next day. Also buy a blender and make protein shakes every day, they are disgusting at first but your appetite will catch up with your new level of exertion and you learn to love them.
