For years, Kurt Sabin, owner of GRIT Obstacle Training, viewed fitness through a lens that many adults recognize, where physical appearance was often treated as the primary measure of athletic capability. That perspective shifted after he entered a Spartan obstacle course race in 2018 and found himself struggling through challenges he believed he had trained for. Despite years of consistent workouts, Sabin left the event questioning whether conventional fitness routines were truly preparing people for the physical demands of real-world movement and resilience.
According to Sabin, the disconnect came from realizing that looking athletic and moving athletically were often very different things. He explains that traditional gym routines frequently emphasize isolated muscle groups while overlooking balance, endurance, coordination, mobility, and movement efficiency. That realization later shaped the foundation of GRIT Obstacle Training, a Michigan-based training facility focused on obstacle-style and functional fitness programs for both adults and children.
