Fat guy and running

Thanks for all the advice. For now, I will look into new shoes for big guys and also a pool workout. Outdoors workouts are limited due to weather. I will continue to use the elliptical trainer as I have been having decent success on this. I will continue my walks that I have been doing also. I will just continue down the path towards a healthier me and keep working to achieve my goals. My knees are fine when I ski. They just don't like the pounding of the running yet. I appreciate all of the advice and look forward to continuing my fitness journey.

Don't let everyone that tells you to "get outside" scare you. I ran 5K - 1/2 marathon competitively, and the bulk of my training was on the treadmill. It's personal preference. I found running outside too easy, and on the treadmill I could time my intervals with more accuracy. I, personally, found I ran faster outside than inside...

Running hurts period. Get good shoes, go to a running center for help. They will be able to determine how you pronate. You don't want to skimp here. Start out very gradually. Do less than you think you can even mixing a little running with your walks. Over time you'll be able to run longer and walk less. If you can find a rubberized track that will help also. Stretching is also extremely important and you may need to do exercises to strengthen the muscles around the knee. Any time I start adding on miles without doing that my knees will start bothering me. A couple days of leg extensions hi reps and light wt always does the trick.
