The quest to become the World's Strongest Man (WSM) is a gigantically strenuous and demanding training process.
Eddie Hall, a strongman athlete from Newcastle-Under-Lyme, weighs in at 28 stone (178kg) - and aims to get to 30 stone (190kg) for this year's WSM.
However, he knows he's pushing his body to the very limit, and it's starting to take its toll.
To get to this weight, Hall has to stick to an incredibly strict diet and eating plan. Each day, he trains for five hours and eats 10,000 calories.
"Yes I'm doing damage to my body now," He told the BBC. "The human body isn't designed to be this size.
"I mean, for God's sake, I'm 6ft 3in and 28 stone. Ideally, someone my height needs to be 15 or 16 stone."
For BBC's Inside Out, Hall underwent a series of tests at Staffordshire University. Despite seeming wary about the strongman's physical health, the researchers were soon surprised by his results.
His resting heart rate was exceptional, as was his recovery time between exercises. His legs also generate the same power as a Vauxhall Corsa.
In short, Eddie should be fine. Though he should probably shave off a few pounds after he retires.
