The King of Winooski boxing.
King James McMillan is a former welterweight boxer and MMA fighter, a five-time Vermont Golden Gloves champion and a world champion in karate. For more than ten years he has coached kids and adults right here in Winooski.

Your success comes from your own effort.
King James has lived the sport from the inside. He fought as a welterweight in boxing and in MMA, won five Vermont Golden Gloves titles, and took a world championship in karate. Then he turned to coaching, and has spent more than a decade teaching kids and adults in Winooski.
His belief is simple. Boxing builds discipline, structure and toughness, and nobody can hand you those. You earn them, round by round. That is why the gym's motto hangs on the wall where everyone can see it: hard work beats talent.
It is also why the gym is built for beginners. Members say it best: King "is super nice and welcoming", and he spends extra time teaching first-timers the basics. Champions are made, and the making starts on day one.
A gym fit for a king.
Walk in and you will see it. A full boxing ring under glowing hexagon lights. A giant crowned lion painted over the ring. Rows of KING heavy bags, footwork ladders on the floor, and a conditioning area with room to work.
It is a serious boxing gym that feels like a community, because it is one. Kids, teens, women and men train here side by side, and everyone is welcome.

In your corner.

In their words.
Amazing Boxing 101 class! The coach was so patient and encouraging. It had been a long time since I boxed, but I felt great getting back into it. The atmosphere was welcoming, and I had a lot of fun. I 100% recommend this class!
Great people and a fun experience. I first showed up with zero experience to one of the Box N Burn classes and had a blast! Worked with one coach primarily but got to meet King and he is super nice and welcoming (everyone is)
My 14 year old daughter had her 1st day today and the owner James made her feel very comfortable, spent extra time with her teaching the basics. He's very knowledgeable and the facility is awesome. Definitely will be a regular!
Had my first private session at King James and it was excellent. Perfect mix of cardio and technique. Excited to learn something new and King James Boxing is the place to do it.
I attended boxing 101 and it was an amazing class. The coaches are great and the class is beginner friendly.
