Angie, jogging is a hard activity and I know this because I used to jog. I got up to about five miles but it nearly killed me. Me knees were always so sore.
Walking is a great exercise to begin a fitness program. You should read my article: Starting a New Exercise Routine
I use walking as the example in the article. It may help you to start out with just one thing, even just one exercise that you do everyday until it becomes a habit. I wish you the best of luck and let me know if I can help you.
Thanks for sharing.
