Pretty much the worst thing you can do exercising is an ACL tear or an Achilles tendon rupture. Both of these are absolutely awful injuries to pick up (whoever designed the human body really phoned it in at the knee joint IMO). Both are usually solved with surgery, and will massively impact your life for 9-12 months. But the real fix to those injuries is to get back exercising again. If Tom Brady can play NFL football after an ACL tear and surgery, you can probably go back running with the right advice.

The only way to avoid injury is to not use your body at all but your muscles will atrophy and you’ll end up injured _anyway_ that way.
