Hi all!
I have a quick exercise question....! I have only recently begun to exercise (today will be the 3rd day) along with having a healthy diet..... I started off at 136 a few days ago, and this morning I'm at 138!!!!

I KNOW I haven't eaten badly.... so what caused this gain?? I read somewhere that, due to exercise and muscles retaining water to heal, you might gain some initial weight when you begin working out........... is this true? Could that be happening to me?
please advise!
