The strongest “muscle” in your entire body is not located in your legs, chest, arms, or back. The human mind is definitely the most powerful “muscle” and a strong mind can push you through any reasonable obstacle. In the words of Henry Ford, “Whether you think you can or think you can’t, you are right.”
“Always make sure to flex your mental muscles!!” The human body is capable of extraordinary things, but a strong body will never achieve its maximum potential if it is attached to a weak mind. On the other hand, a weaker body attached to a powerful mind will continue to grow stronger and stronger as long as the person allows the body to gradually catch up.
