Exercise is not very conducive to pleasure as it's mostly a painful activity. It also not as health-promoting as it's usually made out to be. Harvard professor Daniel Lieberman makes the case in the linked book below that humans have not evolved to exercise.
Observations of hunter gatherers today who spend much of the day just sitting around suggest that our remote ancestors were in fact no less couch potatoes than we are. Dan Buettner who has studied populations around the globe with a high concentration of people blessed with stunning longevity shows their lifestyles to have many traits in common. Among these traits and perhaps the most surprising is the fact that they never exercise. Instead, they tend to engage in lots of natural low-Intensity physical activity, mostly just walking around.
As Lieberman shows, the commodification of exercise today has led to unnecessary hustles, psychogical pressures, weird mental complexes, injuries and expenses. Even in antiquity there were those who said that people highly passionate about exercise are weird. Fitness junkie Ross Enamait who wrote some excellent training manuals says he's been called crazy for his fitness passion.
What are your personal views on the issue? Does exercise make a lot of sense from an Epicurean point of view? Why shouldn't the time and money spent torturing the body with high-Intensity exercises just for some vague notion of 'feeling good about yourself' and impressing your 'bros' not be better invested in more pleasurable activities? Epicurus sure loved visiting the theater but as far I know he didn't visit gyms at all. Do we have any evidence that he did?
