After 10 years of training, James won the "1990 Mr. Kansas" title and competed in the 1990 NPC Men's National Bodybuilding Championships.

James developed the first prototype of the exercise database for his Masters report at KSU. Sometime afterwards, two potential investors offered James financial backing for the development and marketing of a CD-ROM version. These offers were turned down. James wanted his information to be available for everyone with an interest in exercise. A few years later he converted his exercise database program to the web after receiving a grant from Dr. Eric Serrano. His motivation came from his interest in exercise and enjoyment in sharing his knowledge with others. James had spent several years developing ExRx.net as a philanthropy. Currently, the ExRx.net Store and Google Ads provide income for the maintenance of ExRx.net and offers a rationale for continued work on ExRx.net. James converted components of his fitness analysis software (FitTrek) and has added other online fitness calculators to the site. The revised exercise database continues to be a feature component of ExRx.net.
