In this episode of FUEL, we follow undefeated professional boxer Jessie Vargas as he prepares for a career-defining fight against Timothy Bradley, Jr. The goal? Not a pound over 147. We traveled to beautiful Mount Charleston, Nevada to join Jessie’s high-altitude boot camp in preparation for his interim WBO welterweight title fight. Guided by boxing legend Érik Morales and nutritionist Cicilio Flores, Jessie endures long runs, calorie-counting, and closed-door sparring rounds in his pursuit of boxing history.WATCH NEXT:FUEL: Scrambling Up Mount Superior with Professional Rock Climber Alex Honnold: http://bit.ly/1QqcQmFSubscribe to Munchies here: http://bit.ly/Subscribe-to-MUNCHIESCheck out http://munchies.tv for more!Follow Munchies here:Facebook: http://facebook.com/munchiesTwitter: http://twitter.com/munchiesTumblr: http://munchies.tumblr.comInstagram: http://instagram.com/munchiesvicePinterest: https://www.pinterest.com/munchiesFoursquare: https://foursquare.com/munchiesMore videos from the VICE network: https://www.fb.com/vicevideos
