I spent one deployment when I was probably 22 or so trying to bulk up. Another guy on the det was all about fitness and body building and said he could help me out.
He had me track what I was eating for like a month beforehand because I was telling him how I could just eat whatever I want and do anything but not change my weight of about 140 lbs and lean. Anyways, I was eating like 4000 calories of junk. I did his diet plan and was taking workout shakes and whatever. Worked out almost every day. After like 8 months, I was like 143 lbs and 💩 10 times a day. I definitely looked better naked but it wasn't worth all the effort.
Yesterday I was 144 lbs. I still fit in the uniform they gave me in boot camp.
