A martial arts master explains that mistakes in training get locked into muscle memory for about ten years, since muscle cells take that long to renew. The lesson: do it right from the start, or you'll be fighting your own body for a decade.
I heard this profound quote from my good friend Aslak from Finland.
One of the most impactful lessons that my martial arts master ever taught me was about doing things right. When we were training, so he was emphasizing all the time that don't make mistakes now because the cells in the muscle will learn and it will take 10 years for the cells to renew themselves. So we are stuck with the mistakes that we do today. That's why it's super important to do things right every day, all the time.
No matter what your goal is, the idea is to focus and to the best of your ability avoid making mistakes and work and train hard to do things right in the first place.
