But most importantly, they eat a japanese diet.
the diet where even people who don't exercise at all still have the basically the lowest avg body weight and bmi of any developed first world country.

An average japanese teenage girl (age 13-17) weighs between 47-52kg (104-115 lbs.) their avg height is 158cm (5'2").

so basically, diet is your #1 thing. For members with extra nice low-fat bodies like yuiri or miru, obviously they'll probably do a little exercise on top of that.
