For the first time ever, heavyweights and the women's featherweight division will be on display together when The Ultimate Fighter: Heavy Hitters debuts on FS1 on Wednesday night, Aug. 29. To help this latest cast of fighters get to the next level of their careers, middleweight champion Robert Whittaker and top five-ranked contender Kelvin Gastelum will be coaching the 16 UFC hopefuls during the 28th season of the long running competition series. Both Whittaker and Gastelum will bring plenty of knowledge about this format with them to the show considering they have each won The Ultimate Fighter in the past. All told, The Ultimate Fighter: Heavy Hitters will feature 16 athletes representing eight different countries from around the globe. From Australia to Germany to Brazil and everywhere in between, the international talent will be on display as the heavyweights and women's featherweights all look to make a great first impression when the show gets underway.
