About Zac Yonemoto
In 2022, Zac Yonemoto broke the raw squat world record in the 275-pound weight class with a 865-pound lift, no knee sleeves, no wraps, just belt, briefs, and a 12-week peaking cycle built around velocity-based training and bar path micro-adjustments. Unlike many lifters who chase volume, Zac pioneered the 'tension mapping' method: using real-time EMG feedback during submaximal sets to identify and retrain weak concentric zones in the squat’s sticking point. His approach reshaped how coaches analyze strength curves, not as abstract graphs, but as tactile, repeatable neuromuscular signatures. He trains out of a converted auto-body shop in San Diego where the platform is bolted directly to bedrock, and every warm-up set is filmed for kinematic review. Zac doesn’t talk about motivation; he talks about torque angles at 92° hip flexion and why grip width shifts force distribution across three specific lumbar vertebrae. His influence isn’t measured in followers or meets won, it’s in the growing number of regional federations now requiring bar-speed analytics for raw division certification.
