Prevent Injuries

If you feel pain while you work out (not general muscle burn), you should stop immediately and assess yourself. More often than not, aches and pains are temporary and healthy, since your body is tearing and rebuilding muscle. Other chronic injuries can be much more painful and can put you out of commission for a long time unless you treat them immediately.
