My friend and I run at the gym, and i've started being irrationally annoyed at his success. he started "running" about a year ago (i just started about a month ago), and his 'success' consists of not warming up, poor running form (running on the balls of his feet in a pseudo sprint, at high incline hanging off the front end of the control panel), no cool down and no stretching, but he still is the sagely advice type when it comes to running because he can sustain leg motion akin to running for an hour and I cant. basically his opinion is develop the endurance, then develop form later. he's not the only one I know who does this, but it's worse because he's my friend. I know he's wrong and setting himself up for injury, but I don't know how to convince him that he shouldn't be doing this, since i'm a newbie and he's been doing this for a year.
