This is a fairly decent article, but tended to be over simplified in presentation. However, I did learn that males can only expect to generate 1-2 lbs of pure lean muscle mass a month. This is a disappointment. It would take 3 months in best case scenario to gain 6 lb of lean muscle and 6 months or longer in worse case. I just finished a 12 week challenge and found that I was able to gain 5 lb lean muscle during this time through a lot of strength training. For my next 12 weeks, it sounds like setting an expectation of 3-6 lb lean muscle gain would be valid. Does anyone care to refute the claim in the article with regards to a male building max 1-2 lbs lean muscle in a month?
