The link between exercise and happiness is already well established, but the importance of this link is not.
For those interested in understanding what contributes to a joyful life, I would argue an absolute imperative is regular exercise as the scientific literature seems comprehensive in its findings.
Often, we discuss philosophical principles, habits of thinking, and daily practices that happy individuals consistently engage in to lean towards more long-term joy. Eons of religious and spiritual traditions have discussed the psychology of an awakened or ‘realised’ individual, none of which have pointed to this secret.
The secret of exercise.
