Please Help: How come this doesnt hurt?

Question

http://www.youtube.com/watch?v=c_1rdLl3-l8

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

Well those noises he is making doesnt make it sound pleasurable that is for sure.

Why anyone (the girls included) would want to do that is beyond me

Answer 2

Looks to me like it hurts but he probably enjoys those girls jumping on him.
