...who are scared to lift heavy weight because you might 'bulk up'....
clink on this
LINK and scroll to about midway down, there are a series of videos a woman named Karli doing weights. She is lifting INCREDIBLY heavy weights and there isn't an inch of bulk on her. In fact, I find that she is actually quite 'small'...
Hopefully this will help some you ladies to turn your 5lb dumbbells in for some heavier ones...heavy weights do not lead to bulk...
