How many reps should I be doing if I want to increase muscle mass?

If you are looking to increase your size and gain lean muscle mass you should be lifting in the 8-12 repetition range. Anything less and you will be increasing your strength, not size and if you lift more than 12 reps per set you will be increasing muscular endurance which will actually lean you out and decrease the size of your muscles.
