MrBeast couple who won $350,000 after losing 160 pounds reveal hardest parts of five month gym challenge

Sara Mosby and Tre Fontana spent five months locked in a gym for a MrBeast challenge and won $350,000 after losing 160 pounds combined. The couple completed the challenge in 163 days, surpassing their original goal of losing 150 pounds.

Tre Fontana said the hardest part was no communication with family during the challenge. He said not being able to talk to his mother or tell her about his progress was what he struggled with most.

The couple participated in extreme exercises during filming, including pulling a truck around the gym hundreds of times and climbing a rope attached to a helicopter to win more money. Sara Mosby was initially contacted through an Instagram DM from MrBeast's casting team.

Mosby said the opportunity came together quickly, going from working a desk job to filming with MrBeast within three weeks after several rounds of interviews. The couple got married at the end of the challenge and were reunited with their family.
