I actually think the best way to become a runner is to look at your squat and single leg squat to identify potential muscle weakness. If you cannot control your knee motion during these two movements, you will not be able to control your knee movement during the running cycle. If this is the case, I would strongly recommend an 8 week hip strengthening program before you lace up your sneakers and hit the trails. If you don’t have any hip weakness, start slowly, and increase your total time running slowly. I always recommend starting with 1 minute on, 2 minutes off, repeat that 10 times with a five minute warm up and cool down on either side of that. The other thing to be aware of is researchers have shown runners who strike with their heel way out in front of their center of mass have a much higher risk of injury than runners who land with their foot directly under or just slightly in front of their center of mass. Sorry for the long, opinionated response; I am in graduate school right now and the bulk of my research papers have been on running. As a result, I have developed some strong opinions about injury prevention. Good luck!
