I am an overweight 50yo woman. I began running about a year ago and took off 50lbs which I have now gained back 10. I love running and don't really think I overdo it. I walk run and when I am at the top of my game try to get in 5 miles a day, half of which is probably walking. The problem is I keep getting sidelined by injuries. The main problem is my hips and knees. I will get uneven muscle development so my knees track outward and my hips are unbelievably tight. I just started back up again on the treadmill and am taking it very slowly. I'm not letting myself run until my walking speed is faster. During this time I really want to work on strengthening my hips, hamstrings and quads so that they are more evenly developed and increasing flexibility. When I look on line I see millions of exercises. I need to create a simple list of maybe ten things that I can alternate doing. I would like to be able to print them somehow so I can take it with me to the gym and remember what to do. Any advice, even the name of a good book?
