is it just more cells being made? how does one’s bicep for example go from like, a flabby twig, to something shapely and hard and strong? i sort of have a basic understanding about lactic acid and how that makes muscles sore after a work out but how do they get bigger?

They get bigger in 2 ways. More Nuclei or Bigger nuclei.
Satellite stem cells transfer their nuclei to the muscle cells.
Muscle nuclei regulate the metabolic requirements and will determine if the muscle should grow or shrink.
There is no evidence that muscle tearing causing muscle growth, Excessive muscle tearing and lactic acid build up and soreness can lead to muscle loss.
Your body is a house and it is allocating resources to build the most appropriate house for your needs.
It is not tearing out the floor and walls to put on top like a game of Jenga.
“Muscle memory” and the ability to regain lost muscle faster is directly related to muscle nuclei.
