How Sara and Tre Lost 160 Pounds Together in a MrBeast Challenge

Open on YouTube ↗
Overview

MrBeast's challenge for engaged couple Sara and Tre was simple to state and hard to do: lose a combined 150 pounds before their wedding and win $250,000. The video follows them over 163 days, through fitness tests, side challenges with extra money, a stretch of forced separation, and several points where Sara came close to quitting. The video presents the money as the prize, but it keeps returning to two other things: their health, and how much each of them depended on the other.

The Rules: A Gym, a Red Circle, and No Contact With Family

MrBeast opened by showing the couple a gym built for them and calling it a setup for "the biggest transformation on YouTube." The catch was a large red circle painted around their new home. If either of them touched the line before they had lost 150 pounds, the video would end and they would get nothing. Their wedding would also be the first time anyone in their families saw them since the start of the challenge.

The first day did not go well. Sara said she had never seen some of the equipment, called it "an alien concept," and said she felt embarrassed by workout gear she did not know how to use. That evening the gym went unused and the two talked about ordering food. MrBeast's narration concluded that they would need help.

Trainers and Baseline Tests

Each of them got an iFIT trainer, Bree and John. The trainers began by measuring baselines so they could track improvement. Sara managed one push-up. Both ran a timed lap of the track and did hangs and other tests. The narration says the daily structure of improving these numbers gave them enough motivation to get through the first week.

The trainers also mattered for another reason. Sara said that her experience with very fit people had always involved judgment, including from family members who made her feel "super judged." She described hearing comments like "big" and "fat" so often that she stopped reacting. She told the trainers she had never felt uncomfortable with them, and the narration credits this friendship with keeping the momentum going.

Small signs of progress followed. One of them reported 15,600 steps in a day. Pants were getting loose. One of them said they had not had a headache or migraine in about 20 days. Sara said that watching Tre stay consistent felt like getting "a whole new version of him" to fall in love with.

The Medical Picture From Function Health

The couple said they wanted to start a family and run around with their kids, and that their current health made that hard to imagine. The show brought in doctors from Function Health, introduced through Mark Hyman, MD, its co-founder and chief medical officer. The plan was to check insulin, hormone levels, and cholesterol, with the hope that the numbers would improve each month.

Hyman described the day-one results bluntly. Their metabolism was "just busted" and both were pre-diabetic. Tre's insulin was at 100 on a 0-to-100 scale where 100 is the worst. Asked how many years they might gain, Hyman said that all of it was fixable, and that if they fixed it they could live to 90 or 100.

Day 30 and the $50,000 Deadlift Offer

At the first monthly weigh-in, they had lost 43 pounds combined, almost a third of the goal. MrBeast then announced a side challenge. On day 60, they could load as much of $50,000 in cash as they wanted into two barrels on a deadlift bar. Whatever they could lift and hold for one minute would go toward their wedding. Taking the full $50,000 meant lifting a combined 320 pounds.

They chose the full amount right away. The trainers planned three days a week focused on the lift. One of them admitted to never having lifted more than a five-pound dumbbell before the challenge and said the idea of that deadlift was terrifying.

Sara's Low Point

The harder workouts wore Sara down. By day 35 her morale was fading; she joked that whoever designed this deserved "literal jail." By day 39 she was in tears in the middle of a workout. She explained that she had spent 39 days doing this after 27 years of doing none of it. Tre told her they would get through it together, and Sara said afterward that having him there gave her confidence and took pressure off.

They returned to the work, cooking meals together and planning how to spend the money on a photographer, videographer, flowers, food, and a tux. On day 49 they tried the full deadlift weight and dropped it. Sara said this was exactly why she avoided leaving her comfort zone: she does not put herself in situations where she might fail because she cannot handle it, and the failed attempt gave her more reason to doubt herself.

The Clothing Test

To lift their spirits, MrBeast brought in Chandler with new clothes. At the start, one of them had worn a 4XL and the other a 3XL. The new clothes were one size smaller in each case. Both fit, and both were even loose in places. Tre predicted his mom would ask, "Where'd my son go?" Sara said she had never seen herself as someone capable of losing weight or changing sizes. The narration says the clothes re-motivated them, and that despite the hard workouts they had started to enjoy being healthier. Tre summed it up as "Health is wealth."

Day 60: Holding the Bar

The day-60 weigh-in showed 76 pounds lost combined, about halfway. They then attempted the full $50,000 deadlift. MrBeast pointed out when they passed 48 seconds, the point where they had dropped it on day 49. As the clock ran down, Sara's hands began to shake. Tre and the crew counted down the last ten seconds while Sara shouted that she was not dropping it. They held the full minute, and the entire $50,000 went toward the wedding.

The Net and the Helicopter

The next challenge was a tall climbing net. If they could climb to the top within 30 days, MrBeast would pay for any honeymoon they wanted. In a cut to the future, MrBeast told viewers the twist the couple did not know yet: the net would hang from a helicopter 100 feet in the air.

Sara said she had never climbed anything in her life and did not like heights. During training she got stuck partway up, said she couldn't continue, and went inside. She said she was scared of being the reason they did not win. Tre told her she was "10 times stronger" than she thought. Sara said the climb had shaken her far more than she expected.

To cheer her up, the team shared Function blood results: Sara's insulin was down 82% and Tre's was down 83%. They were told this meant they were adding years to their lives, though there was still room for improvement. The narration says these tangible results helped Sara keep going.

Seeing that both of them were afraid of heights, MrBeast revealed the helicopter twist early so they could prepare, adding that they would be harnessed in. The news hit Sara hard. "I'm not Tom Cruise," she said. She described spiraling and admitted that "that red line, sometimes… it's tempting." With her thinking about quitting, MrBeast arranged a phone call with her mother, which the narration credits with getting her back to training. Alison, who was filming a separate MrBeast video in which a different stranger is chained to her every five days, also stopped by. Her advice was to pretend to love heights and lock in on getting into the helicopter.

Day 90: 107 Pounds and the Climb

At day 90 they were down 107 pounds, with 43 left to go. They were harnessed up, the helicopter lifted the net, and they had to climb it and get inside. Sara went first while Tre called up that he knew how strong she was. Then Tre climbed, and despite struggling with the final pull, he got in. MrBeast announced a honeymoon to Hawaii, provided through the Polynesian Cultural Center.

Pulling a Truck: 150 Laps, Then 300

Next, MrBeast showed Tre a Ford F-150. It would be his if, over the next 30 days, he and Sara pulled it around the circle 150 times, about five laps a day. Only the two of them were allowed to pull, and stepping on the red line still meant elimination. After the first lap, both said they were exhausted.

With 56 laps done and 20 days left, MrBeast phoned with a new offer: double the total to 300 laps and Sara would also get a new car, a Ford Bronco. They accepted, which meant roughly 15 laps a day in rain and heat. MrBeast came by to help pull and shared a tip for getting the truck moving: stay still and lean your body weight forward. MrBeast also asked each of them separately whether they could have done the video without the other. Sara said it would have been impossible. Tre said he would have struggled more and been bored, and that being there had made him love her even more. Before leaving, MrBeast hinted that the day-120 challenge would "totally not change everything."

The heat pushed Sara to her limit. She called it the dumbest thing she had ever done, said she had never experienced that level of pain, and repeatedly said she couldn't continue while Tre kept encouraging her. On day 120 they still had two laps left. MrBeast joined them for the finish, and they ended up running the last stretch. Both cars were theirs. They then got in and drove them, and one of them noted they had not driven in months.

The Briefcases and the Separation

The day-120 weigh-in showed 130 pounds lost, with 20 to go. MrBeast then revealed the final challenge: $50,000 in cash and five briefcases, each holding a fitness task. Each of them could win $25,000 by completing a task in 30 days. They had to accept or reject each briefcase before seeing the next one, and a rejected briefcase was destroyed.

The first briefcase was ten pull-ups, which was quickly passed. The second was a one-minute bar hang, and Sara took it, saying she knew she could manage a minute in 30 days. Tre passed on a 36-inch box jump and then on an eight-minute mile, calling it too hard and choosing to "risk it for the biscuit." He was left with the fifth briefcase: 30 push-ups.

Then came the twist MrBeast had hinted at. A second gym had been built, and Tre would train there alone for the next 30 days. Sara had spent the whole video saying she couldn't do it without him, and she said she had never gone more than 16 hours without talking to him. MrBeast explained that this was the point: until now they had leaned on each other, and the goal was to see whether they could succeed as individuals.

The gyms were close enough to see each other but they had no way to communicate. Sara watched Tre's garage door through her glasses all day, waiting for him to open it. When they finally saw each other, they could not hear anything. Both said they were bored, that time was moving slowly, and that they missed each other. Sara said her motivation had "plummeted." MrBeast then reminded them what they were working toward, and the narration says this renewed their determination. During this period, the team also covered some of the bigger wedding costs. Sara chose an item she wanted "sparkling" and picked her wedding dress with her mother. Tre picked his tux with his father, who noted that 80 pounds lost meant "a brand-new life." The narration says they trained harder over the next ten days than at any point in the video.

Day 150: Reunion and $50,000 More

On day 150, MrBeast let Tre cross the red line and return to Sara. Tre went first and completed 30 push-ups for $25,000. Sara then did the one-minute dead hang. When she arrived she could not hang for more than a second; now she said she felt confident, and she held the full minute for her $25,000.

The weigh-in showed 144 pounds lost, six short of the goal. They promised to lose the rest within 15 days.

Hyman then gave a fuller account of their health. He said they had been in some of the worst health he had seen. Tre had the testosterone of roughly a 90-year-old and probably could not have had a baby; that level had since doubled. Sara's celiac markers had returned to normal, her insulin had gone from very high to normal, and she had PCOS, which Hyman said causes infertility. According to Hyman, everything had normalized for her, and both now had much more energy.

The Last Days and the Letters

Near the end, the trainers said they no longer had form cues to give. The couple described a bittersweet feeling. One of them called it almost a rebirth and said that after most of the year there, all they knew was waking up and working out. When a trainer asked Sara about the most money she had ever had in her bank account, she answered $8,000.

After their last workout, they read letters they had written to themselves five months earlier. Sara's letter said her mental health was severely affected by her lifestyle, that she hated herself most of the time, and that self-doubt had kept her from prioritizing her health. She hoped that showing up for herself would change that, and that she and Tre would live "strong, long, and healthy lives." Tre's letter said he didn't know the last time he had looked in the mirror without feeling disgust, and that he hoped his future self felt better and was proud.

41:50

Final Weigh-In and the Wedding

At the final weigh-in on day 163, Tre reported a starting weight of 345 pounds and Sara reported 249. Together they had lost 160 pounds, beating the goal. Counting the $250,000 grand prize and the $100,000 from the two cash challenges, MrBeast deposited $175,000 into each of their Step accounts.

At the wedding, MrBeast said the red line, which "used to represent losing," now represented winning. The couple stepped over it together. It was Tre's mother's first time seeing him since before the challenge. In his vows, Tre said their six years together had been the best experience of his life and that he would support her even on bad days. Sara said she had watched him become a new man over 163 days, that he made her want to work harder, and that he had kept her grounded "when I was at risk of fleeing." The video ended with the kiss and MrBeast saying, "I don't think we're gonna get a better ending than that."
