ELI5 scientific reason strength training takes away aches and pains

r/

Why does muscles pain go away after strength training? So I have a lot of aches and pains in my neck and shoulders. I went to the gym today and exercised upper body and my muscles and joints are feeling amazing! It was cables and machines and not very heavy, what gives?

    I may be wrong, but I think the increased blood flow and released endorphins do their magic while we exercise.

    You get an endorphin rush and since you now have more “damages” on the muscles your body kinda ignores all the pain in order to function, in the long term your muscles get stronger and give better support so you get better posture and less stress on the joints for example
