Answer 1

If you mean muscle soreness, it has actually nothing to do with growing directly.
Muscle soreness are micro rips in the tissue, they occure when you do an eccentric exercise that you are not adapted to.

Thats why riding the bike basically gives you no muscle soreness, it’s basically just concentric.

As soon as u build some muscle around the „micro injury“ it stops ripping again. Thats why you shouldnt train for muscle soreness. Its actually a good sign when it stops.
