Default the physics of situps

I recall an old article in Scientific American from 1980 called "The Physics of Somersaulting and Twisting". It described how
divers for example could start their body twisting without an initial moment and nothing to push off of. Not available online but
I'm sure you could get it through the library - google search reveals a lot of references to the article.

I might point out that a bird can also fly, and a fish can swim,
without having anything to push off of.

Except of course air and water. They couldn't do it in a vacuum. Are you
really that stupid or is this some more champagne trolling?

Hi Neil Gendzwill,
I have goggled "The Physics of Somersaulting and Twisting" on net and found lots of results. Not sure which one to read.
I will be kind if you will share the article with us.
