"Muscle mass does not always equal strength. Strength is kindness and sensitivity. Strength is understanding that your power is both physical and emotional. That it comes from the body and the mind. And the heart."
little excerpt I thought might fit with this subject.
"When I see guys working out for cosmetic reasons, I see vanity exposing them in the worst way, as cartoon characters, billboards for imbalance and insecurity. Strength reveals itself through character." -Henry Rollins
