Hello I’m a 58 year old who is extremely overweight with arthritis in my back, high blood pressure and a sluggish Thyroid. I do walk at least 3x a week for 30 min and I am mindful of eating healthy. I never really was a runner. I friend of mine told me about the C25K and explained how this is the program for me to drop the weight. So I bought myself some good running/walking shoes and will be starting my 1st day in week 1 today! Wish me luck!
