Learn to Box, From Someone Who Has

Undisputed Boxing is a personally coached boxing gym in Hucknall, Nottingham. Small groups. Real technique. Led by John Machin, a former competitive boxer with fifteen years of coaching behind him.

No experience required. Just the desire to show up and learn.

This Is Not a Boxing Class

Most gyms will put you on the pads, count your reps, and tell you that you're boxing. You're not. You're doing a fitness session with gloves on.

Undisputed is different. Here, you learn the actual sport. Footwork. Defence. Combinations that work because the technique behind them is right. Coached by someone who spent ten years competing, not someone who did a weekend course.

Sessions run in small groups, capped at four members. That means every session is personally coached. Your technique gets attention. Your progress gets tracked. You are not a number.

What You'll Walk Away With

The Skill
Real boxing technique from day one. Footwork, stance, guard, combinations, and defence, built properly from the ground up, not layered over bad habits.

You will understand why each movement exists, not just how to copy it. That is the difference between someone who has done boxing and someone who can box.

The Physical Results
Boxing is one of the most complete forms of training there is. Members have dropped up to five stone in six months. Others have quit smoking, got off medication for depression, and overhauled how they eat and sleep.

The results follow the consistency. Turn up, put the work in, and your body will change. That is not a promise we make lightly.

What Changes Beyond the Gym
Discipline that follows you home. Confidence you can feel when you walk into a room. Stress that has somewhere to go. A version of yourself you knew was there but had not unlocked yet.

This is boxing as a training environment. The thing that changes is you.

This Is For You

  • You have always wanted to learn to box properly but never found the right place to start.
  • You have trained in gyms, done the programmes, and found yourself going through the motions. You want something with real skill behind it.
  • You are carrying more stress than you have time to deal with and you need a physical release that actually challenges you.
  • You are in your thirties, forties, or fifties and you want to get in the best shape of your life without treating fitness like a chore.
  • You have an old injury and you need a coach who will build sessions around you, not around a template.

And if you think you're not the boxing type:

The members who train here are not ex-fighters or gym regulars. They are self-employed men, professionals, dads. Men who wanted something that felt serious. Most of them had never boxed before they walked through the door.

You do not need to be the boxing type. You just need to want to learn.

Your Coach

John Machin. Former Competitive Boxer. Fifteen Years of Coaching.

John spent ten years competing in boxing before building Undisputed from the ground up. Not as a side project. Not as a franchise. As the thing he has done every day for fifteen years.
He has personally coached hundreds of members, from complete beginners to men preparing for competition. Every coach on the Undisputed team has been selected and trained by John to the same standard he holds himself to.

When you train here, you are learning from someone who has been in the ring and built a business on the quality of what he teaches.

Real People Real Results

We do not just talk about transformation. We deliver it.

I have loved training at Undisputed Boxing, which is quite unusual as I don’t really enjoy fitness training generally.

I have really enjoyed learning boxing which is taught in a really friendly and welcoming atmosphere.

Boxing training at Undisputed has become a regular part of my life which I would really miss if I ever stopped training.

Just to name a few of the benefits I have improved my fitness, strength, lost weight and boxing has really helped me with my mental health.

Leigh Jackson 44 Burton Joyce

I’ve been a massive boxing fan all through my life attending many fights, including Chris Eubank and Prince Naseem Hamed.

I had a flier through my door from Undisputed Boxing. I was in my early fifties and was going through a tough time personally.

I decided to give Undisputed a try and I am so glad that I did. I love being part of the friendly community there and all the trainers are so welcoming.

The level of fitness boxing has given me at my age is incredible and the workouts are a blast, I look forward to the training every week.

Andy Graves 60 Hucknall

Before I started training at Undisputed Boxing I was 110 kg and out of shape.

Since I’ve been training I have lost over 15kg and have become much more confident and outgoing.

I absolutely love the training and it has made me fall in love with boxing even more.

No matter what is going on in my week, boxing is the biggest thing I look forward to and I highly recommend training with Undisputed. Give it a go it will change your life.
