Ah! Yeah, don't worry about that. Those scales are *not* accurate for anything other than weight (and even that needs to be calibrated to make sure). So I wouldn't worry if I were you.

If you haven't had a physical in a while though, now might be a good time since you are working out and it is always good to be checked out for tip-top shape.

And if you have...woohoo! Keep going. :)
