In Russia, MMA fighter Maxim Novoselov was fighting against a bear. He actually owns that bear and a lion! Maxim was featured on RTM before when he was training with an axe. We're guessing the next MMA fighter he goes up against is in for a tough fight.
Over in Florida, an arm wrestler named Sarah Bäckman was doing a challenging workout. She has won eight arm wrestling championships so far, and we can certainly see why!
