Hey guys I am 15 years old and 5'8" and 110 pounds. I am pretty skinny and want to gain some muscle but mostly want abs. I do chinups and pullups everyday (I can do 13 chinups and 8 pullups) but nothing really helps. I eat a regular amount (not anorexic or anything) and no junk food, but nothing I know helps. Anybody have suggestions? I have a chinup bar, but no other equipment.
Thanks
Thanks
