Are you one of those people that check their weight everyday? First thing in the morning or after a workout is usually the norm. I'm here to tell you... STEP OFF THE SCALE!!
It is not necessary to check our weight everyday or every other day, for that matter. If your trying to lose weight the 'HEALTHY WAY', You may only be trimming down 1-2 LBS per week; you may also be putting on muscle with your weight training program. It is better to check your progress every two weeks (one week if you're on a very intense program). Mark your calender and make an event of it. Not only will you be happy with what you see, it will keep you motivated day after day.
And to take this a step further... be brave and throw your scale out completely. Is there a dress, pair of pants, bathing suit or suit that you want to fit into? Use that as your benchmark. Monitor how your clothes are fitting, as a way to tell if you're on the right track or not, or have a loved one or trainer, measure your girth measurements (around your waist,arms and/or thighs) every two weeks, and watch those numbers disappear.
DON'T BE A SLAVE TO THE SCALE!!
Health and fitness is a lifestyle.
