Another commonly asked question is when should I weigh myself. Personally I don’t like my clients to weigh themselves frequently. I believe it focuses the mind on how much you weigh and not how you feel.
I know people like to use how much they weigh as a measure of how successfully they’re losing excess fat but life isn’t as simple as that. Muscle weighs more by volume than fat so the same sized piece of fat will weigh less than the equivalent sized piece of muscle tissue.
Considering our goal is to build muscle whilst working out this can skew the results we see when we weigh ourselves. The overall percentage of body fat we’re carrying (BMI) can go down but our weight could stay the same. In other words we’ve lost fat and built more muscle but may show disappointing results when we weigh ourselves.
How much we weigh should only be used as an indicator to fat loss. Much better is how do our clothes feel – are they just that little bit looser? Do we feel better in ourselves and have more energy?
So jump on the scales if you must but do it once a week, at the same time (I prefer first thing in the morning) and naked! Then make a note and forget about it. If you are following the program given to you by your Personal Trainer then rest assured you will get the results your looking for.
Be patient remember Rome wasn’t built in a day, you didn’t put the weight on in four weeks so why would you expect to lose it in four weeks
