The thing about long distance cardio is that it gives you so much time to think the most ridiculous things if you're not completely zoned out .. the first long distance run i did half way through i was holding conversations in my head that went something like "why are you torturing yourself? stop stop you suck at this anyway!" etc etc o.O

sorry if i'm in d wrong thread but since females do not bulk up with muscle easily,are there any other reasons a woman's frame seems to get bigger when she starts lifting e.g. bone structure,etc?

example:
a female friend of mine started lifting weights and after a couple of weeks her shoulders got wider.
