Two individuals start the same training program at the same time, but one is able to grow muscle faster and larger than the other. What is the least likely explanation for this?

Respuesta :

The least likely explanation for this would be that they're training at different intervals, or one is training harder than the other.  

The most likely reason is that the way the other person's genetics are most people cant gain muscle as well as others because of disease or their body structure.

Hope this helped!
