The 1-2 pounds of lean muscle a year rule
I don't know where to put this thread so I'm leaving it here.
Let's say that someone is naturally 225 pounds by the age of 25 and 5-6% body fat. so 211 of everything else… I don't know exactly how much bones and organs and water weigh but lets just assume a conservative 70%. That leaves 64 pounds of muscle and muscle is actually kind of heavy so I'm guessing theres even more. Thats a lot more muscle than 1-2 pounds a year for 25 years. 14 pounds more at the lowest most conservative estimate.
Where did that 1-2 pounds of muscle even come from and how accurate is it really?
