how do i take my measurments?

i think they track neck waist and hips, waist at narrowest point and hips at widest point, if you don't have a tape measure use a piece of string or the flex from a phone charger or something and google online ruler! I also added bust (widest point) thighs and upper arms ... I always measure in cm and once i've started i don't measure again until i get a little disheartened by my weight loss or if i feel my progress is slow, then i remasure as seeing my loss in a different form can give me the boost i need to stay motivated and that all my hard work is paying off ... i measure in cm as mentally you feel like you have lost more and so is more of a boost
