I have taught judo since I was 13 years old when the coach arranged for me to pay my YMCA membership by helping to teach the beginning judo class. I thought about this recently when I was asked for the 7,823rd time
“What age are your games appropriate for?”
It’s probably reasonable for children to start doing push-ups and sit-ups around age 8. It won’t damage them to do these exercises sooner, but if you take a good look, you’ll see that children’s heads are much larger in proportion to their bodies than in adulthood. This disproportion decreases with age. So, around age 8 is a good time to begin these exercises.
At what age are push-ups and sit-ups no longer good exercises? When I was in my twenties and training for the world judo championships, the first thing I did when I got out of bed in the morning was drop down to the floor and do 50 push-ups and 50 sit-ups.
As someone who travels for business a lot and spends a lot of time in hotel rooms, I can tell you that these are good exercises into your fifties. I don’t do as many or as often as I did in my twenties, but push-ups and sit-ups are still good to keep in shape.
It’s the same way with reading, with math problems.
We make games that are like push-ups for your brain.
