No Pain No Gain

No pain, no gain (or "No gain without pain") is a proverb, used since the 1980s as an exercise motto that promises greater value rewards for the price of hard and even painful work. Under this conception, competitive professionals, such as athletes and artists, are required to endure pain (physical suffering) and stress (mental/emotional suffering) to achieve professional excellence. Medical experts agree that the proverb is mostly ineffective for exercise.
