How many exercises?

Many people often wonder how many different exercises they should do to adequately train a muscle group. Sometimes this can be a fine balance because if you do too few you might not be getting as much benefit from your routine, but if you do too many you can easily over-train. As a general guideline, if you're a beginner you should do 1-2 exercises per body part and 2-3 sets of each exercise. If you're at an intermediate level, you should do 2-3 exercises per body part and 3-4 sets of each exercise. If you're at an advanced level, you should do 3-4 exercises per body part and 3-5 sets of each exercise.
