For anyone worried about knee injuries from running, or shin splints I can highly recommend weightlifting, in particular squats, as an auxiliary exercise. I kept on running, getting pains in my knees and resting for two weeks and then just doing it again. After six months (way longer than probably necessary) of progressively lifting higher weights I went back to running and I’m doing my first 50K next week, having done a 35K up and down mountains previously. My first run after the long period weightlifting I just decided to run a half marathon distance to see if I could. The muscle pain the next day was less than I often get from lifting.

I do tennis a few hours a week and my knees have started hurting after a period of summer inactivity. I'm thinking of taking up gym squats again, my knees never felt better than when I was squatting. I could effortlessly climb up stairs like it was nothing with just a few weeks of weightlifting, I need to get back on that (and recommend it to anyone).
