Early life and introduction to boxing

Tapia was introduced to boxing while living in New York, when his parents took him to a gymnasium in order to control his weight and quickly employed his energy excess to establish a high-intensity training regime. He developed an admiration for the boxing styles of Wilfredo Gómez and Muhammad Ali, which influenced his style and created a preference towards technical boxing, instead of brawling and pursuing a knockout punch.
