Hi there! Great blog! I just wanted to post my 2 cents on gaining muscle. Lifting weights won't actually make you gain muscle UNLESS you're eating at a nice surplus (which I doubt you are since you're doing a DB). If you see new muscles - cool! But it's because you're uncovering lean mass you already have. You can't gain muscle at a caloric deficit. Your body doesn't work like that. Any gains you see are likely water, because lifting does cause the muscles to retain water as they repair.
