So I'm not exactly sure what to call myself. Im 17, 5'11, and 145lbs, I'm by no means big, but im also not the skinniest guy you've ever seen. Im at a generally low body fat level, probably between 10-12%, my abs are visible but not particularly defined. I have been in crossfit since i was 13, started out over weight, but quickly got that fixed with a combination of growing and crossfit. But I got to a point where I wasnt getting anymore results, and my lower body was drastically stronger than my upper body. My squat was at about 200lb and my deadlift about 260lb, but my bench press was 95lb, and that was just too uneven for me.
So in a way I am a beginner, but i know a variety of lifts and movements. I am now at another gym, but clueless as to what to do because crossfit had pre-made workouts. So i guess my essential question is, what would be most beneficial for me to build muscle?
Also, because i started out over weight, I have a pretty hefty mental barrier against gaining any fat. So im hoping to keep my fat down, and maybe even lower it as well. So any advice would be much appreciated!
