Iand 21 and want to be a ble to run a mile in under 8 minutes but I can't run very far without feeling really bad pains in my chest like a heart attack and I am unable to breath. I am healthy and active, but when I try intense stuff I have to quit before it really gets bad.
What are some ways to gradually work around that? I am completely new at running.
