when your muscles are beginning to feel fatigued, that is when the real training starts. if you stop every time you start feeling that burn, you won't gain any strength. you have to go over that threshold and keep working to make any progress. the way you know to stop is if you start feeling faint, like you might black out. then it's time to stop, walk around for a bit, no more than a sip of water, and concentrate on returning your breathing to normal.
pulled muscles are caused by training without properly warming up and stretching, or by demanding way too much work from it. you'll never pull a muscle just from training for an extended period of time, there has to be some other factor.
the only real sign you should stop training is if you feel dizzy or faint.
and i agree with dc that if on some days you just don't feel up to hard physical training, that would be a good time to work on the other side of the martial arts. qigong exercises, meditation practice, candle watching, leaf counting, these are all things you can do when your body is not up to external training. however if your mind is also tired, it's best to nap or do the simplest meditation practice (sitting cross-legged, clear your mind, keep it that way). you'll feel re-energized after, and it's pointless to practice anything else if you can't focus.
