My experience is that the scale doesn't move very far without taking bodyfat% with it. In 8 years, I'm yet to find a way after the first few months of training to gain any visually recognisable new muscle mass without gaining fat with it, ultimately requiring a cut as a result. Attempting to build muscle without gaining fat resulted in me remaining skinny. After noob gains, nothing happened to my muscles until I did accept fat gains.
Do you have experience to support what you're saying? Any photos, or at least measurements to demonstrate that doing it the way you recommend gets good results?
