I just got this book from my local library and I am finding it to be very interesting. I also think it will help me minimize the knee issues that sidelined me and get me running again! Give it a look

The athlete's book of home remedies : 1,001 doctor-approved health fixes & injury-prevention secrets for a leaner, fitter, more athletic body! / by Jordan D. Metzl with Mike Zimmerman.

If nothing else, check out his video at:

He has a number of similar videos that cover a wide range of ways to get and stay fit. Running and nothing else is not the greatest solution.
