How do I stay safe on a treadmill?

First make sure the treadmill is in working condition. You don't want to be working out on a treadmill that malfunctions. You should also definitely use the safety clip so the treadmill stops if you fall. Some runners tend to run too far up on top of the console of the treadmill, which can actually cause you to hit and slip on the actual structure of the treadmill instead of the belt, so be careful not to do that. Run at a pace that you're comfortable with. Don't get competitive and look at people on your left or on your right. Watching TV or listening to music can sometimes can be a distraction when you're using a treadmill.
