Think you’ve got to be on some inside track to become a celebrity trainer? Not really. Jay Cardiello, creator of the J-Core program, did so by accident. Literally. A martial artist for most of his youth, Jay left his New Jersey home after high school to attend the University of Arkansas where he was part of the 1996 national championship track & field team. He was there to become a lawyer, but an accident on the track would not only send the disks in his vertebrae “flying every which way,” but also his career plans. He landed wrong during a jump and the damage to his spine would require 13 major surgeries over the next few years.
