In studies of falling, researchers have shown that the wrist alone is subjected to an impact force equal to about one body weight, says James Ashton-Miller, director of the biomechanics research laboratory at the University of Michigan.
“What so many people really need to do is develop enough strength so they can break a fall safely without hitting their head on the ground,” Dr. Ashton-Miller said. “If you can’t do a single push-up, it’s going to be difficult to resist that kind of loading on your wrists in a fall.”
You youngster’s may not know Jack LaLane, he once held the world record 1000 pushups/23 minutes. Check out his finger tip push-ups :
