When you start working out, you will have soreness in your muscles from lactic acid because your body isn’t used to it.

Once you get in a routine of doing it at least twice a week you won’t get that soreness anymore. People who start working out, then miss a month, then start back experience it all the time. Consistency is key.

When you start drinking something like unsweetened tea, initially it's almost unbearably bitter. But as you drink it long enough, it feels less and less bitter. It didn't get any less bitter, you just impaired your ability to sense this kind of bitterness.

I wonder what happens with muscle soreness. Do they get actually get less sore after consistent exercise? Or do you just blunt your nervous system into not detecting chemical signatures of the damage? I'm guessing it's the second case because people here are commenting that after exercising long enough you can still have gains but no pain of muscle soreness.

They get less sore, because they're more adapted to the stress of exercise. The hardest DOMS comes from movements you're not used to.

Or from the damage in places that your nervous system didn't yet get blunted to.
