as a professional wrestler shortly after the Olympics, he broke his leg in the fall of 1996. But by the summer of the following year he had rehabilitated it enough to be able to compete at the USAPL National Powerlifting Championships 1997, where he won the competition to become the U.S National Powerlifting Champion in the Super Heavyweight class again. He had planned to continue heavy training in powerlifting, although his travel schedule as a professional wrestler with the WWF (now WWE) has made sustained training difficult. Mark's WWF contract was unique in many ways, allowing him at least three months off each year from wrestling, so he can train for the national and world championships in weightlifting or powerlifting. Barring injury, Mark had originally hoped to return to the platform in late 1998, to lift for many more years, and to eventually squat at least without a “squat suit” and to deadlift . Although in early 1998 he was still able to do five repetitions in the bench press with , three repetitions in the squat with (with no suit and no knee wraps), and three repetitions in the standing press with in training, while traveling with the World Wrestling Federation, he never returned to compete again in official championships in favor of his wrestling career. He weighed at that time, and his right upper arm was measured at 24" by Terry Todd. By basically ending his lifting career at the age of 26, it is probable that he never reached his full physical potential as a professional lifter. Henry remains the youngest man in history to squat more than 900 pounds without a squat suit as well as the youngest to total more than 2,300 pounds raw – he's the only person ever to have accomplished any of these feats at under 25 years of age.
