i'ma be straight up honest. i'm a skinny ass nigga. i was about 5'4", 125 in 9th grade, and now i'm 19 and only around 5'6" and 135. right now i'm doing 3 sets of 135 (10 reps and usually struggling on reps 8, 9, and 10 on the last set). the thing is, i don't really gain weight at all when i eat. you see i've only gained 10 pounds in what...4-5 years? and when i don't work out, my muscles just shrink and i'm just short and slim as hell. i know push-ups are a big factor, but what else can i do to increase my bench?
