A hardgainer is someone who is naturally thin and has an extremely difficult time gaining weight of any kind.
Therefore, why listen to someone who gains muscle easily?
Anything they say will not be relevant to a hardgainer.
What we finally discovered after years of failed effort is that most pros are not only gifted with good genetics (i.e., they can gain muscle or lose fat easier than most people), they also enhance their results with illegal hormones and steroids.
Because of this, they can train harder, eat whatever they want and still get great results. Using their training methods and advice would never work for the body type of a hardgainer without the use of steroids.
This brings us to you, are you gifted with fantastic genetics? Or, life me, are you a hardgainer? If the latter, please continue to explore this webpage.
