The Bialecki brothers began boxing as young as 8 years old, their gloves barely bigger than their tiny bodies. Recently retired from MMA, their father, Tyler, has built his own gym to coach his kids like professional adults. However, children's boxing is highly controversial — the American Academy of Pediatrics discourages any child from boxing due to concussions and bodily harm. Despite the risks, the Bialecki family believes it's worth it, as the best way to avoid getting hurt is to become the best. In this episode of Child's Play, we follow the family as they prepare for a big fight in their new town.
