Get rid of the scales!
FORGET the scale NOW!
When in exercise mode, we are constantly looking for the immediate feedback that will tell us we are getting healthier, leaner and stronger. We then opt for standing on weight scales to tell us how we are doing.
Weight scales, however, are just registering what your body weighs and are not a measure of how healthy you have become, how much lean muscle tissue you have gained, or how much fat you lost.
When you are training properly and following sound nutritional advice, your body composition will change. The best measure of how you are doing is to literally look in a mirror and notice the changes and actually feel how your clothes are fitting. The pants will be looser, the shirts will fit better, and your posture will improve.
When embarking on a fitness challenge, as an example, you should put on a pair of pants that you find are fitting too tight. From there, every 2-3 weeks try on the pants again and notice the changes. Feeling healthier and sexier in your clothes gives the self-satisfaction that will make you want to keep it up.
