In 2020, the number of women buying boxing gloves doubled. While more girls are participating in boxing studios more than ever, it’s still rare for women to be coaches. Meet Summer Jiao, the Muay Thai instructor whose ex-boyfriend’s fat shaming catalyzed her journey to boxing. Muay Thai is known to be brutal, fierce, and violent, especially when you watch athletes in merciless matches. But the practice is about decisiveness, speed, persistence–and is a great test for observing and collecting your thoughts. After practicing for 8 years, 27-year-old instructor Summer has devoted her life to boxing and says it gave her reason for existence. Students like Yan Bao, who is also a mother, agrees that Muay Thai isn’t about violence as much as it is about peace. Being strong in your body, able to kick properly, and run fast is about safety and calming your mind–especially as a girl or woman out there in the world.
