Muscle soreness

Just created a post, not sure if people even know to read the comments haha.

Anyways I think the big thing is the microscopic tears. Lactic Acid is cleared out within a few hours so that is not going to be the cause. The others seem more related to fatigue than soreness. Another cause not mentioned is misalignment of the muscle fibers.

I don't see soreness as something that is bad as long as it doesn't prevent you from working out again in the window of supercompensation.

Here is an analogy:
So I am really pale and I want to get a tan. So I go out in the sun for 15 minutes and the next day my skin is burnt. So I stay inside. My body increases the pigment in my skin to make me a little darker and better able to deal with the sunlight. So I go out in the sunlight again for 15 minutes and this time I don't get burnt. I am dark enough to withstand it.

The rest of the month I go out for 15 minutes everyday. The question is how dark do I get at the end of 30 days?

The answer: Not any darker, I will get just enough to last 15 minutes.

Now think of going to the weightroom. If I go and bench press 100 lbs and I am not able to handle it, I will be sore the next day. (sunburnt) It will send a signal to my body I need to get stronger (darker) If I keep doing the same exact thing I won't get any stronger. Funny how some people will lift the same thing everyday and wonder why they aren't getting stronger.

Soreness lets me know I created a sufficient stimulus to cause an adaptation. The goal is to not get so "burnt" that I can't go out in the sun for longer then increase in pigment lasts.

Soreness is not necessary to cause adaptation, without it though you need to wait a few weeks before there are any noticible changes. Soreness is one of the few immediate signals that you are creating an appropriate stimulus. Which might be good for motivation.
