"Nobody, certainly not Hetrick, thought the gizmo, 'a true invention of necessity,' would be of much interest to civilians. Some 17 years later, that gizmo, now called TRX (Total-Body Resistance Exercise), is a fitness phenomenon. But Hetrick wasn't just lucky. His rise from amateur inventor to fitness entrepreneur proves that a good idea is only half the battle." -TRX CEO Randy Hetrick in Men's Health Magazine, June 2014.
