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.

If you want to avoide the heat, go outside early in the morning (like around 6-8). If you don't want to run, you could always join a swim team. There, you would be motivated by teammates to try your hardest and it'll be a good workout everyday.

For the food part, get into the habit of reading food labels. If the first ingredient is sugar, avoid it! Follow the food pyramid, stay away from greasy, fatty foods. Eat salads, fruits, and stuff.
