“On Monday through Thursday, I would do stationary running in my cell in the morning for up to forty-five minutes. I would also perform one hundred fingertip push-ups, two hundred sit-ups, fifty deep knee-bends, and various other calisthenics.”
“I have always believed exercise is a key not only to physical health but to peace of mind” and “I worked better and thought more clearly when I was in good physical condition”
– Nelson Mandela
