Simplicity and Moderation in Pursuit of Physical Fitness

Seneca highlights the importance of simplicity and moderation in pursuing physical fitness. He criticizes excessive efforts to develop muscles and obtain physical strength, arguing that such pursuits do not contribute to true health and can hinder the mind's activity. Seneca advises limiting indulgence in food and focusing on exercises like running, lifting weights, and jumping, which are simple, time-efficient, and effective. He emphasizes that the primary focus should be on exercising the mind through philosophy, as it is nourished by moderate labor and can be engaged regardless of external factors like weather or old age.
