Thiago 'The Pitbull' Alves beat Jordan Mein at UFC 183 the other night with a kick to the body so fierce, it won him a 'performance of the night' bonus ($50k) from UFC President Dana White.
Alves fights in the Welterweight division of the UFC and regularly works with fitness and nutrition guru Mike Dolce, who helps the fighters make weight for their bouts.
Dolce posted the short, but intense video below of the Brazilian fighter doing a conditioning session a week or so before his fight.
It's worth noting, he'd do this multiple times and it's a very small part of what his training would be. Still. Intense!
