For the first time ever The Ultimate Fighter competition will feature the biggest male and female weight classes in the UFC. Eight heavyweights and eight female featherweights from around the globe come to Las Vegas to compete on The Ultimate Fighter - Heavy Hitters. After coaches Robert Whittaker and Kelvin Gastelum introduce themselves, they run the fighters through drills to evaluate their skill sets. Then UFC President Dana White arrives, greets the group, and the coaches pick their teams and choose the first preliminary matchup. After the fighters move into The Ultimate Fighter house, team training sessions get underway. While Team Gastelum's practice is intense, with the men and women sparring together, the Team Whittaker session takes a lighter approach to training. Back at the house, one of the heavyweights enjoys drinking alcohol before and after training, which raises some eyebrows among the other fighters. Then, in the first preliminary fight of the competition, two fighters lay it all on the line for a spot in the semifinals.

With the first fight in the competition in the books, Kelvin goes straight back to work, putting his team through an intense conditioning session. One of the heavyweights struggles throughout, raising concerns over his ability to perform in his fight. During Team Whittaker's practice, the coaches turn their attention to their upcoming featherweight. She's familiar with her opponent and plans for a stand up battle. Back at the house, Team Gastelum's upcoming featherweight shows off pictures from back home and talks about how fond she is of her pet. Through home video footage, we meet her family, boyfriend and, most importantly, her adorable dog. As her competitor keeps mostly to herself, we learn more about her and her life back home through her own self-shot footage. At the gym, it's Team Gastelum's turn to prepare their fighter. She's very excited about the matchup and believes her opponent may be underestimating her skills. A couple of days later, as Team Gastelum is about to start another training session, their next featherweight has a mishap, which lands her in the dentist office in need of a painful procedure. The fighters make weight and go to war the next day. The first featherweight semifinalist is revealed and the coaches pick the second heavyweight fight.

After an intense battle in the Octagon, one of the featherweights is carried through the front door, bruised and battered, by her heavyweight teammate. As she dwells on her defeat, her opponent gets drunk by the pool, relishing in her victory. At the gym, Kelvin brings in his friend John Walker, a former football player-turned-trainer and motivational speaker. Walker puts the team through a series of vigorous drills, and gives them words of encouragement along the way. At the house, the Team Gastelum coaches pay a visit and enjoy some adult beverages with the fighters. The visit makes Leah continue to wonder if switching teams might be in her best interest. Maurice does his best to recruit Leah to make the move, but in the end she decides to wait and see what happens in the next several days. In the morning, Josh opens up letters that his family sent him from home and reads them aloud to Marciea. Then, in the fifth preliminary fight, two heavyweights face off in the Octagon with a spot in the semifinals on the line.

Fresh off the third preliminary fight, Team Whittaker is back at the gym and hard at work preparing their next featherweight fighter. They hope her unique background and skills will prove to be too much for her veteran opponent to handle. Back at the house, her opponent shares the hardships she endured as a young gay woman and, through her home video, reveals how she overcame her past and built a great life for herself. The following day, Kelvin surprises his fighters with two guest coaches from his hometown. As the practice unfolds, Kelvin receives an unexpected gift that leaves him speechless. Meanwhile, Whittaker decides to take his team on a fun paddleboard outing. Kelvin then turns his attention to his upcoming fighter, who is confident her opponent is just a one trick pony. As fight day approaches, the fighters exchange words at the house and the tension rises in anticipation of their bout. At the gym, a featherweight begins to worry that she's not getting what she needs from her training and starts to contemplate the possibility of switching teams. Finally, an action packed roller coaster of a fight reveals the next semifinalist.

With only one fight remaining before the live finale, Team Whittaker sits down with their last featherweight to watch tape and analyze her opponents preliminary fight. At the Team Gastelum practice, Kelvin decides to give his team a break and they all play a friendly game of dodgeball. Meanwhile, Team Whittaker's fighter is hard at work at the gym preparing for a tough matchup. As the fight approaches, Team Gastelum's featherweight decides to sit down with her coaches to review her own previous performance. They compare her last opponent to the next challenger and come up with a game plan at practice. At the house, Team Whittaker's featherweight pushes herself to the limit by putting in extra workout sessions in the backyard. Back at the Gastelum practice, their upcoming fighter finally has had enough and she breaks down during the training session. Later, the team rallies behind her at the house to help with a difficult weight cut and the two competitors have an uncomfortable run in with one another. After barely making weight, the two featherweights battle it out in the last fight of the season. Finally, the finalists all face off in anticipation of the live finale.
