Isaac "Chism" Cornelison is a student from Texas who joined The Biggest Loser season 13. Due to an accident when he was 10 years old, he spent a lot of time in a wheelchair and sought comfort in food brought by friends and family. This resulted to his sedentary lifestyle and massive weight gain. As a college student taking up film production and screenwriting, he hopes to land more roles in theater and participate in activities like skydiving and rock climbing.
