The old myth that running is bad for your knees. It isn’t unless you have a condition. What you may not have is tendons ready for the effort or the right supporting muscles. These can be worked on.
The main thing 90% of people will benefit from is learning to activate their glutes, then strengthening their glutes. Clamshells are a great place to start.
A lot of people hurt their knees because their glutes don’t activate and are weak from sitting all day. This forces them to become quad dominate, which puts more strain on the knees.
Some need to walk before running. Walk the distance you want to run (e.g., 10K) and your body will tell you where your fitness level is at. I walked a month before running.
