Couch-to-5K Running Plan

I love to exercise and I've been working out at the YMCA for about 5 years now. Before that, I did Jazzercise - also for about 5 years. While I do love taking the classes at the Y, I feel like I need something more. I have several friends who run & they have unknowingly motivated me to try it myself. (Thank you Gay Lynne, Margo, Ashley & Allana! Now if I have a heart attack, it's your fault!) I actually used to run growing up with my dad. We always enjoyed running in the Tulsa Run every year as a family. Well, now I'm old & it hurts my knees and feet to run! I'm hoping if I start out slow that I can work my way up to running a few miles without having a heart attack. I found a website that has a "simple" plan to follow for beginning runners. Their site says, "The Couch-to-5K Running Plan is a beginner's running schedule that has helped thousands of new runners get off the couch and onto the roads, running 3 miles in just two months." I'm starting tomorrow so we'll see how it goes!
