Stray Dog Strength, founded by Matt Purdy after he built his first rack in 1998, makes modular strength-training equipment for sports performance facilities. The Newark-based company pioneered its modern rack system and now operates as a second-generation family-owned business, with products manufactured in Columbus and designed to adapt as training programs change. Its equipment is backed by more than 25 years of sports-performance design experience and includes custom facility planning and installation.
