Best rep range to build muscle faster

Which rep range is best for muscle growth? 6 to 12 reps has been the standard recommended rep range for hypertrophy or adding size.

Unfortunately there are problems associated with very high rep ranges as well. So watch this video and find out exactly how many reps and sets you should be doing to see optimal muscle growth.
