Right in the middle of it all at this year’s Arnold Sports Festival is the YouTube fitness star and face of Tiger Fitness Marc Lobliner. Him and his brand MTS Nutrition are basically at the center of the Columbus Convention Center with a 360 booth, serving customers from all angles. While MTS doesn’t exactly have anything new, it does have some incredible show specials that will likely attract just as many people. At the MTS booth visitors can also purchase supplements from a few other brands that Tiger Fitness sells including Sean Torbati’s HPN and the new Chris Jones brand Pump Chasers.
