Gus is an English Bulldog that hangs around The Foundation, a fitness center owned by his humans, Alexis and Matt Karstetter. Gus will plop on the treadmill or greet customers as he goes around the center. He is also the official mascot of the center! In addition to his usual rounds, he also joins in on workouts, as Popsugar details:
"No matter what I'm doing, he is either sitting in between my legs or staring at me sitting next to me (I swear he's judging me or correcting my form in his head lol)," Alexis wrote to POPSUGAR via email. "He LOVES self-propelled treadmills and will start running without any coaxing. He is also slightly obsessed with medicine balls and BOSU balls." If you browse through Gus's Instagram account, which has amassed over 28,000 followers, you'll see that he has a knack for sneaking up into Alexis's space mid-sweat session (one viral video ahead shows him going up under her sweatshirt during a plank hold!).
