On physical exercise
The New York Times recently published an article that was channeled through The Irish Times about how push-ups can improve your physical health’.
“Simple, strenuous and possible to do almost anywhere, push-ups are an almost universally known exercise and a mainstay of military, sport and fitness training regimens. Push-ups are a ‘basic, foundational movement’, said James Whitener, a strength and conditioning coach.”
I used to do a lot of push-ups as a teenager. It may have been partly vanity, but strong arms can be a good thing. There is a scene in the later part of the last Christian Bale Batman movie where he uses push-ups while in jail to regain health after a villain breaks his back.
