After more than a month walking at a fast pace everyday, my body seems to be adapting and now I need to walk at a ridiculously forced high speed in order to feel it sort of challenging. So I want to start running.
But I am doing air squats once every three or four days or so. The number of squats has steadily been increasing too, and I plan to restrict them to once a week.
Running might impose some stress on my knees, so I want to run only once a week as well, at least for the first month until I am convinced that everything goes well.
So, my question, which one the following two alternatives is best, in order to minimize the risk of knee injuries?
Running and squatting on the same day. Good: it allows a whole week for the knees to recover. Bad: the stress on the knees imposed by the two things on the same day might add up and increase the risk of injury.
Running on, say, monday and squatting on thursday. Good: Both activities don't overlap in the same day, minimizing the amount of stress within the same day. Bad: only two/three recovery days between activities that put stress on the knees.
