Become
unstoppable.
Boxing, conditioning and Taekwondo in Winooski, Vermont, led by King James McMillan: former welterweight boxer and MMA fighter, five-time Vermont Golden Gloves champion. Total beginners, kids and women especially welcome.



Boxing builds discipline, structure and toughness. Your success comes from your own effort.
That is the whole philosophy of King James Boxing and Fitness. King James McMillan has coached kids and adults in Winooski for more than a decade, and he built this gym so anyone willing to work can learn to box properly: under hexagon lights, around a full ring, on rows of KING heavy bags, with coaches who know your name.
You do not need to be fit to start. You need to show up. We take care of the rest, one round at a time.
- Real boxing, taught from the stance up
- Kids 5 to 12 in their own classes
- Women-only boxing and bootcamp
- Conditioning that never gets boring
Eight ways in.
From a five-year-old's first jab to race-day HYROX conditioning. Pick the one that fits, and try it free.

Teens and adults
Hard work
beats
talent.
It hangs on our wall, and it is the deal we make with every member. Nobody walks in a natural. Everyone walks in with something to prove to themselves.
Show up, put in the rounds, and listen to your coach. The gloves, the technique and the confidence come with the work. That is how ordinary people in Winooski become unstoppable.
Built for women who want more.
Two of our classes are for women only. Learn real boxing in Pink Gloves Boxing, or get stronger in Fit Fem Bootcamp, with women coaching women. And every other class on our schedule is just as open to you.



Nervous? Good. That means it matters.
Never thrown a punch? You are exactly who these classes are for. Here is what to expect.

- 94 West Canal Street, Winooski. Down the street from The Woolen Mill, with plenty of parking.
- After class
- No pressure. We will walk you through the options to keep training, and you can ask about the first-day sign-up bonus.
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.
