It is surprising how even people who have the benefit of the two legs and arms intact find it difficult to do a simple press up, but 21-year-old young man with a rare genetic disorder that made him lose his two legs and one arm was filmed lifting a 152lb tire nearly a dozen times across his Tampa, Florida gym.

Nick Santonastasso has a condition known as Hanhart Syndrome which is a genetic disorder that affects the growth of limbs in babies, and has a survival rate of only 30 per cent.

A footage, uploaded to YouTube Wednesday, shows Santonastasso lifting the heavy black tire at least nine times, pushing himself to get every rep in at an impressive speed.

In another video named ‘My Life Story’ uploaded to his You Tube account, Santonastasso claims that he is one of only 12 people that have ever been born with the condition, saying ‘Of those 12, 8 of them are dead.’

The young man first garnered attention with his prank videos, most notably when he costumed himself as a zombie and frightens Walking Dead star Norman Reedus.

His Instagram account is also packed with selfies at the gym, tirelessly working out, strengthening his body, and usually with a smile on his face, an indication that he enjoys what he does.

In his latest video, Santonastasso tried to make people stop underestimating him, saying the condition did not affect the other parts of his body.

‘It only effected my (limbs), my organs are healthy,’ he stated further.

‘I got my early internet notoriety from my pranking videos. I then decided I wanted to become a fitness model, motivational speaker, and a body builder.
