Derrick ‘The Black Beast’ Lewis is currently riding a massive 3-fight win streak that most recently saw him knock out Gabriel Gonzaga in April. With that being said, Lewis is currently gearing up for the biggest fight of his career as he faces Roy Nelson on July 7th at UFC Fight Night 90.

Ahead of that fight, Lewis has traded in his traditional heavybag for a set of hanging tires. See the clip of the hardcore training method, used by many Muay Thai fighters for shin conditioning, above!
