Suzi, something else to keep in mind, it's possible the scale will say you've gained. This is why it's important to have other measuring sticks; a tape measure, a pair of test pants and before and after photos.

It's very common to see the number on the scale go up when you start lifting heavy weights. Building muscle requires tearing it down first, which causes inflamation and water retention. Gaining muscle before you see the fat loss is also common; there are weeks when the scale says you weigh more but the pants are looser. The scale, ultimately, is not your friend!

So before you start tomorrow take some measurements and write them down and try on a pair of pants that don't quite fit right now. You'll be happy you did
