My upper body won't grow

[aimglows]

So I'm 130 pounds, 5'10, used to be a wrestler for 3 years, we trained in the gym in the morning and in the afternoon for 2 hours, didn't notice any improvement on my upper body except my abs, my arms are skin and bone and you can see my rib cage and most of my weight is in my thighs and I can say it has some muscle.
