I count my official weight as that on the gym scale. I weigh in on Mondays and change my profile then if it needs to be. I am fully dressed, with shoes on and have eaten breakfast already. I always weigh before my workout though. Sometimes during the week, I will weigh myself at home, however, my scale at home will change significantly by where I put it on the bathroom floor, so I really don't trust it that much. The one at the gym is digital and I can't get it to lie..lol ( and believe me, I've tried)!
