you sir are an idiot, lifting weights doesn't make you bulky, it actually assists in losing weight as more muscle mass equal more fat burned. If you knew anything about fitness you would know that. And for someone starting back into fitness, you start with small goals then work your way up. If she thinks that she can run a mile in 15 min then let her, then encourage her to go faster. Weight loss is not an overnight thing, for it to stay off it takes time.
