I've never heard "husky" used for anything other than describing a voice.
Well I wouldn't call anyone 'ripped', or indeed 'zaftig'. ;-)Many on the thin side don't work. Many athletic people and most people you'd describe as "muscular" or "ripped" are not "skinny."

The picture brings to mind emaceated, cadaverous, twiggy for the thin girl.
The fat man suggests distended, gargantuan, porcine. No offence intended.
Would people say "horizontally enhanced"?
