As to laziness and genetics ... known quite a few women who's exercise has beaten the genetics. At least for now.

My sister-in-law was very heavy. Her daugther, my niece, became a a ballet dancer. Thin as a read and yet muscles like steel. Know of another friend, became a cross-country runner. Her mother is heavy, but she's svelte. Mind you, one day, in their 40s or 50s and with less exercise, genetics will take over. For sure. But active exerecise can defeat genetics when one is younger, most definitely.
