I have been walking for 15min 3 times a day. I am going to increase that starting today to an hour. I really want to run but I don't want to overdo it. I will wait until next week to start running. I will start out by running for a minute then walking for two. Gradually increasing that every other day. That way I don't send my out of shape "bod" into shock. I'll let ya know how it goes.
