In 1999, Matthew Castaneda began developing exercise programs for his friends and family. As his reputation grew, so did his clientele base, which quickly expanded to include business professionals, athletes, and stay-at-home moms. More than a decade later, and with countless hours spent perfecting his craft, Matthew opened the doors to Pasadena Muscle Company in his hometown. There, he does what he's always done: engineer customized workout programs for people interested in building mass, losing weight, or gaining strength. In addition to one-on-one training, Matthew also offers boot-camp-style workouts conducted in small groups.
