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

Best Answer - Chosen by Asker: It is very simple! there are two ways that he can take that,

A.) he is bringing his stomach up at the same time as the girl jumps on him that way he is meeting the impact that way it doesn't hurt as much

B.) he is tightening his muscles and guts!

C.) how do u know that he is not in pain he looks like he is in pain!
