I started weight training about 1988. Within a few months I blew a Mitral valve and ended up having a mechanical replacement in 1990.
No more weights for me! Walking is my thing, but not to excess!
I heard Michael Savage say once that light exercise is the key to good health and long life. The stories here about the damage done and repaired needed due to excessive weightlifting are testament to that, I think.
We certainly can’t look to our genetic background to suggest we should be doing anything to our bodies that requires surgery that wasn’t available in the past. Also, the extent to which a modern exercise routine at a gym mimics what primitive man would do in the wild is questionable. There would’ve been more varied movement and physical activity on a hunt or on a farm, not being locked in position on a machine.
And, of course, ingesting any kind of supplements, especially unnatural ones, could easily have unpredictable and deleterious effects on one’s health. Not to mention doing that is TOTALLY unnecessary if your goal is to improve your health.
Physical health is a worthy goal. Men becoming obsessed with their physical body image the way that a young woman suffering from anorexia or bulimia does is not. Human history tells us how harmful and destructive vanity is to the human spirit.
