Probably far cheaper too
They used to do that in schools here with blankets! I bet that does go back to ancient times.
The Inuit still do it!
Hey, they used seal skins of a very large seal species. People held the skin and gave it the power. This was a better thrill than the trampoline and everybody got exercise.
THAT I didn't know.
I didn't know that!
Interesting, I wonder if parents back then made other kids parents sign waivers before jumping on their 'trampoline' lol. I had that happen here with a friend of my sons...ya..
It's a simple enough concept that I'd expect something like it to exist in various cultures and various periods of times.
