What happens to your body during and after running (on treadmill or otherwise)?
What about the impact on my joints during running?
Running can cause a lot of impact on your joints, especially if you're running on hard surfaces or wearing improper shoes. This can lead to knee pain, ankle sprains, and other injuries. However, running on a treadmill can help reduce the impact as the surface is usually softer and more shock-absorbent.
