Kevin called two friends to trample his stomach.
They will step on Kevin's stomach, stomp on his stomach, step on his stomach together at the same time.
The feet of the guys will also change - socks, bare feet as well as sneakers, slates and dirty shoes!
Can a skinny guy handle all that fun on his belly?

Guys weight - Kevin 60kg, Friend #1 - 62kg, Friend #2 - 65kg.
