The Olympia Expo is the official home of Olympia Weekend—and it’s always a packed house. In 2014 more than 55,000 bodybuilding fans and fitness enthusiasts flocked to the expo at the Las Vegas Convention Center. This year, even more foot traffic is expected. Whether you want to watch pre-judging for the Mr. Olympia (or another pro bodybuilding, physique, figure, fitness, bikini, strongman, or powerlifting competition); collect bagfuls of swag; sample new supps; or test out the latest workout gear and exercise equipment, there’s no shortage of things to see and do at the Olympia Expo. For those who plan to partake in the madness on Sept. 17-20, consider putting these seven expo events on your radar.
