Training is only part of the picture. How you move the other 23 hours matters just as much.

Anywhere in the 0.7 to 1.0 range builds about the same muscle. Going higher mostly helps you stay full while dieting. Pick what fits your appetite.

What this actually means
Small moves, big swings

Your daily burn isn't fixed. Watch what a few habits do to it.

Every number here is a smart estimate. Activity level is the biggest lever, so be honest with it. Sleep, stress, food quality and hormones all shift real burn. Use this as a starting point and adjust from the mirror and the scale over 2 to 4 weeks. New to this? Loop in a coach.
