I used to weigh myself everyday but was told that's the worst thing you could do for yourself and your self esteem. You fluctuate so much day to day. I am trying to weigh myself at most once a week to every two weeks. In fact I will have one weigh in before the Team20 final one because my trainer wants to see where I am. So that means I will weigh myself once on May 31st and then not again until June 30th. How often do you weigh yourself??
