4. Too Many Reps
This is a hallmark of the gym newbie that just makes me sick. You can’t take a 10 lbs weight and expect to see some major gains because you do 100 reps. That will build muscle endurance, but it won’t do much in the way of gaining size. Yeah, sometimes it can’t be helped, particularly if you don’t know any better, but take the time to think about this logically. The heavier the weight the more likley you are to put on muscle. Light weight and high volume has it’s merits, but not where building bulk is concerned. Keep the weight moderate to your strength level and aim for a 10-12 rep range.
