Who We Are

Bio – Mark & Cathy Cornelison:


Mark Cornelison wanted to go on The Biggest Loser because he was ready to make the life changes necessary to get healthy and hoped to give his “smokin’ hot wife a smokin’ hot husband!” He says a poor diet and lack of exercise led him to start gaining weight in high school. As a youth pastor of nearly 20 years, his weight had reached an all- time high and something had to be done.

At 43 years old and 295 pounds, Mark suffered from high blood pressure, high cholesterol and acid reflux. As a pastor at the time, they both enjoyed doing volunteer work and leading mission trips, both of which were being significantly effected due to their weight. Mark knew it was time to make a life change when he began taking an anti-anxiety medication in efforts to deal with the side effects of his three other prescriptions. A married father of three – two sons and one daughter – Mark was cast as a contestant for The Biggest Loser in season 13 with their oldest son, Chism.

Screen Shot 2013-10-07 at 3.02.52 PMAfter Mark left for the show, Cathy decided to make changes for herself so that the two of them could share this journey together. She began researching all she could about nutrition and healthy eating as well as developing a consistent exercise routine. By the time Mark returned, Cathy had lost 40 lbs. on her own and had created a home where healthy living was the norm.Mark returned over 100lbs lighter with a new life. He currently has no medical conditions to be monitored and has been removed from all of the medications he was taking before this experience. Besides being role models to their family; their greatest joy is now having the physical and mental ability to do and be anything Christ calls them to be. 

Since the show ended, they have traveled across the US to encourage others. In 2012, they founded SweatCor and now work to communicate hope and encouragement with students and adults alike in regards to ministry and health. Their SweatCor blog is ready by thousands every week and provides regular encouragement to focus on health but also a relationship with Jesus. Mark wrote of the amazing things God has taught them in his book, Undressed, and they have also written a 30 day devotional as well as a nutritional guide to motivate and help others the journey to health. They also have developed and seen great success with their Fit to Serve program which has been used by individuals as well as churches and schools across the country.

This experience has deeply changed them and their family…and they still feel this is only the beginning.

Bio – Allen “Buddy” Shuh:

Buddy Shuh is a pastor from Wayne, MI whose life has been transformed. He was thrust into the national spotlight when he was selected to be a contestant on the tv show “The Biggest Loser”.
Buddy was born on an army base in Germany and grew up in the states of Michigan, Ohio, Florida, and Texas. His father successfully climbed the corporate ladder with a fast-food chain, so it was common for Buddy to travel.
Buddy graduated from Eastern Michigan University with a degree in mathematics. His giftings with numbers helped him to excel in the business arena. He managed restaurants for several years, then managed retail stores. In 2000, Buddy made a career switch and became a teacher. From there, he went into full-time church ministry.
Buddy was an athlete in high school, selected as team captain of both his football and wrestling teams. After graduating, he slowly drifted into an unhealthy lifestyle. By 2005, he weighed in at 300 pounds.
In 2005, tragedy struck Buddy and his family. His second child, Isabella Harmony Shuh, was born with serious complications. She was missing a spleen and a kidney. She had stomach and heart issues. She also had a serious case of spina bifida. The five and a half months that his daughter lived were filled with a mixture of hope and sorrow.When Buddy’s daughter passed away, he temporarily shut down on many levels. One of these areas was in the arena of diet and exercise. He tried to find comfort in food. It was only five years later that he found himself at a weight of over 400 pounds.

Screen Shot 2013-10-07 at 3.16.19 PMIt began to dawn on Buddy that his health was out of control. One day he was looking at his two daughters and knew that he needed to make some changes so that he could be around to walk them down the aisle one day. In July of 2011, Buddy’s brother called him and informed him that NBC was having an open casting call for “Biggest Loser.” He agreed to go, never dreaming that he’d actually be selected for the cast. But God, in His love for Buddy, had other plans. Buddy was selected and placed in the best environment possible for healthy living. Six months later, Buddy was a transformed person.

His beginning weight on the show was 403 pounds. He was the heaviest contestant on his season. Six months later, he weighed in at 230 pounds. He lost about a pound a day for a half of a year! His waist size went from 54 to 36. His shirt size went from 5XL to L. His blood pressure was 190/110 so the doctors had put him on three different types of medicine. He is no longer medicated and his blood pressure is 120/70.

Buddy believes he has been given a gift and is trying to bless others with what he has learned. He speaks in schools, businesses, and churches, sharing that going after the dreams in your heart is a pursuit worth undertaking! He tries to bring hope wherever he goes!


What Others are Saying:
“Tonight was a great night and I so appreciate you leading us! Our total class lost 187 pounds throughout this time! Wow!…Some of them finally got past that plateau and are really pumped that they are losing again! Just think, if it hadn’t have been for The Biggest Loser and Mark and Chism being chosen, all of these people’s lives in Decatur wouldn’t have been changed! I love it when God uses a secular program to do his work! Most of all, I have grown so much through this! I know God put this passion in me and I want to serve Him. It hasn’t been easy all of the time but with you guys encouraging me and the ones who have been through this previously, it has been a total blessing and worth it all in so many more ways!”

“For the last few years, my family has watched The Biggest Loser. Each year we find a contestant or two that we pull for. This year was no different as we found ourselves drawn to Mark and Chism. Because we pulled for them on the show it was incredible to have the opportunity for them come and share with our group about their experiences. Their stories and experiences were inspiring to all who heard them. I would recommend having them speak to your group as well if you have the opportunity to do so.”
