getting a little healthier, over the summer Options

[bambamboozle]

okay, well, I'm not really healthy and it sucks. I'm not saying I'm fat because I know I'm not, just I want to live a healthier life style. The thing is, my mom is sort of...fat, so things around the house aren't that healthy and I was never raised to be active.
So, I want to try to get healthier over the summer. Thing is, I don't want to have to run outside in 90-100 degree weather (I live in Texas). So, do you guys know what I can do that will help me lose some weight and get healthier. Something that I could slowly progress into perhaps. I'm concentrating more on my lower body (calfs, abs, thighs) Plus what kind of foods should I eat... without going on a drastic diet that is?
Any help from here would be nice.

Lift?

Lift?

Actually, that's a really good idea. You won't lose weight with lifting--in fact, often times you will gain wait, because muscle weights more than fat--but you'll most likely be thinner, and having more muscle mass means your body uses more calories to maintain that muscle mass, so you won't have as much energy being stored as fat.
