Teens with 10-25 lbs to Lose

I have no idea how to exercise. I can't go to the gym because I can't afford the membership. I can't go for a run because it's freezing here. I also feel very self conscious when my friends see me running...(I am known among my friends and classmates for being very proud of my car, which I am, which makes it weird that I am running...) What can I do for exercise?

Maybe biking, but as you say it's freezing... Maybe, when it's not freezing annymore you can go for a run early in the morning, like 6am (or earlier), then no one wil see you.
You could always try to start weight lifting with homemade dumbbells (fill a couple of bottles with water or sand). There're lots of exercises you can find online.

Give up your pride and go running. Who cares about others opinions? You should be working out for YOU. It's the quickest way to shed weight and I promise you won't be cold for long if you just go at it. If you really insist that running isn't an option try following some cardio workout videos on youtube. Lots of variety so there's no doubt you'll stumble upon some that fit your needs, they can be quite fun and best of all it's free! (:
