The 2021 Kern US Open, sanctioned by the World Raw Powerlifting Federation (WRPF), was expected to be a proving ground for world records — and the first one is now in the books. Many people associate 90-kilogram dominance with powerlifter John Haack. After all, the man does own two world records. However, on April 24, 2021, Chad Penson was first to the record books with a 400-kilogram (881-pound) squat. He is the first man to squat 400 kilograms at a bodyweight of 90 kilos (198 pounds) in the Raw With Wraps category.
