I am 22 5'7 and about 130lbs. I have been weight training for about a year now but I just can't get bigger. Most of my lifts have stalled because my lower back and shoulders don't permit me from using heavier weight. I have been eating close to 4000 calories daily for the last month, but my weight just won't budge. My body looks almost childish, and I really need to put on some muscle mass for my sport (soccer). Any ideas? Hormonal issues? Low T? High cortisol? More calories? Too much soccer (I only play about 5 hours a week)? More protein; I have done high fat and high carb but have never increased my protein above 130? HCL? Or should I just call it quits and stay at my weight, although I don't want to.
I just find it odd that some of my friends put on muscle with just 2000 calories but I can't seem to do it with 4000 calories so there has to be some underlying problem that I am not aware of.
