|Hey, I have been weightlifting since i was a freshman so almost two years ago and overall my physique has changed from being skinny to moderately muscular in about 2 years. But ive hit a snag. My upper body is great; such as my pecs, back, traps, and somewhat my shoulders but my arms in my opinion are still relatively small compared to my body. I have done bicep curls, dumbbell curls and just about most of the simple bicep moves but i havent gone up so much in weight in those categories and my triceps have gotten more toned but my whole physique goal is bulking up. I recently reverted back to a lower weight to perfect my form about 2 weeks ago. Is there any suggestion to bulking up my shoulders, biceps, and triceps? and why my biceps wont grow?
