Here is a picture of one pound of fat and one pound of muscle. Which do you think weighs more?
Answer: THEY WEIGH THE SAME!
Muscles takes up less SPACE than fat! One pound of fat burns 1-3 calories per day whereas one pound of muscle burns 30-60 calories per day. That’s quite a difference! Now tell me, which would you rather have? I’m working towards muscle.
