what I have to do when i get back to running after school. - this is what I've been doing (at my own pace) for the past 4 months and I've lost 30 lbs and I now consider myself a runner! Not bad for a girl who didn't even run when she was a kid in school!
FORM IS KING! Before you even bother stretching make sure you’ve jogged in place, done jumping jacks, something. You don’t want to strain a muscle trying to stretch it if it doesn’t have fresh oxygen in it. Be careful not to over stretch in your warm up.
