In this martial art demonstration 2 girls (about 110-130 pounds) jump on a guys stomach from a chair.

How can he take that?

Thanks

Answer 1

Actually it's pretty simple. He maintains air in his lungs and pushes downward with his diaphragm when they jump. The air in his lungs keeps them from breaking his ribs. He might have a bruise or two, but even that is unlikely.
