Who's abs can take more punishment?
Jennifer Thomas and Riff Simmons challenge each other to see who's stomach is tougher in a belly punching contest. Both challengers end up very red, trading bare fisted blows and slapping each other while trading verbal barbs for any advantage one can gain over the other. Riff, feeling his abs weaken under Jennifer's powerful punches, is the first to bring out the dirty tricks, flipping Jennifer to the ground then pounding her abs while she's on her back. The action heats up as both Jennifer and Riff not only punch, but add in a few flips, tosses, low blows and more in order to make the other surrender.

Spoilers --
In the end, it's Jennifer Thomas standing over Riff Simmons as he submits to her strength, laying there with very sore abs!
