Guys, Please Help my Biceps!!!

i like to do EZ Bar curls but i keep my palms facing outward... its kinda hard to explain, usually when doin EZ curls ur palms r sort of facing an inward angle toward the body, u need to grab the bar so they are both facing outward... if ur doin it right then it will feel weird and much harder but i totally pays off when tryin to make the peaks grow also i stick with 4 sets of 8 reps.... hope this wasnt too confusing GOOD LUCK

Thanks guys, thanks for all the help...Im going to just split my triceps and biceps into seperate days. Maybe more concentration curls as well...but i didnt know genetics had to do with size of the muscle.
