I'm a woman, 20 years old, 5'9" and 150 pounds with an athletic physique. I have these big, muscular biceps that make me look masculine! Think Venus Williams. :( I've tried to shrink them with exercise (slow-twitch muscle fibers) and have been unsuccessful. I don't think lipo is an option, because the problem is muscle, not fat (they don't jiggle when I wave them around). Is there a procedure that can decrease the size of my biceps? Or a botox injection or something? Thanks!!!
