People work out for various reasons. Some do it to stay healthy and active, others do it to feel comfortable in their own skin. But working out to stay alive?
What sounds like a fairly strange hypothetical is actually the reality of this ridiculously fit 25-year-old personal trainer from Belfast, Ireland.
When he was just seven hours old, Ben Mudge was diagnosed with an incurable genetic condition known as cystic fibrosis.
The disease mainly affects the lungs and the digestive system, making it hard to breathe and maintain a healthy weight. Patients like Mudge need to take medication to keep their body in working order. Failing to do so can lead to respiratory complications and heart failure.
He says he always struggled with putting on weight. So at 20 years old, he adopted a new training schedule.
Mudge hits the gym five times a week, which allows him to keep his lung capacity at 98 percent. Which is almost unprecedented in cystic fibrosis patients.
"Exercise forces me to use my lungs, which helps beat mucus build up," Mudge told The Daily Mail.
It also helps to develop his legitimately jaw-dropping physique.
Mudge says that he is strictly against taking steroids, although people often assume that he does after seeing his muscles.
"The reason I'm doing this is in the first place is to stay healthy. Steroids will not help me achieve that," he told A Plus.
As a personal trainer, Mudge does his best to help other people fight their illnesses, such as anorexia, and is an inspiration to many people living with cystic fibrosis.
However, Mudge points out that his routine is definitely not the cure for his disease and that every cystic fibrosis patient needs to find their own path to health.
He dreams of becoming a Calvin Klein underwear model. And with his superman attitude, it should be any day now.
