Boxing coach Richard Shepherd watches as Maria Campos, 12, spars with a partner at Barrio Golden Gloves boxing gym on South 31st Street on May 9, 2017. The gym originally started out of a garage on the South Side and continues to teach traditional boxing techniques to boxers of all ages. Campos has been going to the gym for nearly two years, training more than once a week. She became interested in the sport after watching her uncle Salvador Campos III box at his home in Billings. He began showing her boxing techniques when she was 8 years old.
