Andrew ''AJ'' Jones, a professional fitness model from Farmington, Connecticut, was diagnosed in 2012 with a rare medical condition called hypertrophic cardiomyopathy.
The condition leaves the heart muscle thickened without any obvious cause.
Jones needed a transplant, but since he was placed on a waiting list, he received a left ventricular assist device, a mechanical pump that transported blood from his lower heart chamber throughout his body just as a heart would.
Without a discernible pulse and a working heart, he relied on an artificial heart, constantly connected to two batteries and a computer that he carried in a backpack wherever he went.
Although he didn't have a self-functioning heart, Jones continued to do his press-ups and other gym routines even in his hospital ward with gadgets attached to him.
His experience with hypertrophic cardiomyopathy informed his decision to establish his own organisation called Hearts At Large to raise awareness for the need of donors and create a network for those in need of donations.
Jones found a matching donor and underwent a heart transplant three years ago.

In other news, Briefly News earlier reported that while fitness enthusiasts dream of a fridge filled with only nature's goodness, the rest of South Africa certainly doesn't want the same for themselves - a local fit woman's post proved this to be the case.
Taking to Twitter, popular health and wellness trainer FitZamaswazi shared a photo of the fridge she would love to have in her home that was full of nothing but fruits and vegetables of all shapes and sizes.
"Fridge goals," she captioned the post.
Locals did not seem to have the same goals in mind and were soon in the comment section sharing how they feel about a refrigerator full of nothing but greens.
