Think of the truth behind this statement, “scar tissue is stronger”. Our body is so smart. Our body does develop calluses just anywhere, it builds tough skin where we need it most. We have calluses on our feet and our toes to protect our skin from tearing or blistering, so we can go the distance. A guitarist has calluses on their finger tips, making it possible to play songs for hours and hours. I have calluses on the palms of my hands from lifting weights, which allows me to lift heavier and work harder without hands giving out before my muscles do.
Basically, calluses are nothing more than scar tissue on top of the skin. Anywhere the skin has been invaded or broken, new scar tissue is laid down to mend that area and make it stronger for the next attack. As you hit the gym and work hard to eat healthy every day, it will be the difficult days that make you stronger – not the easy ones. No matter what challenge you face, whether in the gym or in your personal life, celebrate it – and realize it’s an opportunity to strengthen your body, mind in spirit.
