Two very different sessions, but both a big part of Mayhem.

Boxing is fast, fun and a brilliant workout. Kettlebells help build full body strength, power and control.

Both sessions can be adapted for every fitness level and you’ll be training alongside a really supportive group.

Which one would you choose?

What a weekend with Team Mayhem in Snowdonia!

A challenging climb, some incredible views, plenty of laughs and a very cold dip to finish the day. Everyone supported and encouraged each other from start to finish, making the whole experience even more special.

So proud of everyone who took on Snowdon and helped make this such a brilliant weekend. For me, this is exactly what Mayhem is all about. Taking on challenges, supporting each other and making some brilliant memories along the way.

What a team and what a weekend!

And we’re not finished yet, with the high ropes and caves still to come!

Team Mayhem have arrived in Snowdonia!

A lovely first evening together, enjoying some food, a few drinks and plenty of laughs before we take on Snowdon tomorrow.

Really looking forward to sharing another Mayhem adventure with this brilliant group

It’s always a bit strange talking about yourself. I’m much happier coaching a session, joining in with the training or having a laugh with everyone, but here goes…

I’m Matt, the founder and head coach of Mayhem Fitness MK. I’ve been coaching for 15 years now, and Mayhem came from wanting to create the kind of place I would want to train myself: outdoors, welcoming, challenging and full of good people who don’t take themselves too seriously.

I genuinely love coaching and seeing what people can achieve when they begin to believe in themselves. I’ll always encourage you, usually challenge you and occasionally give you the proverbial kick up the bum when you need it. There will definitely be some banter along the way, but underneath that, I care enormously about the people I coach and want everyone to feel noticed, supported and part of what we’ve created.

Training has always been a big part of my own life. I’m a Goju Ryu karate black belt, a runner, a keen strength trainer and a Superhuman Games winner. I’ve also taken on plenty of other challenges over the years, including rowing the Channel for charity. I’m naturally competitive and always looking for the next challenge, but I know that progress looks different for everyone. For some people it’s winning a competition; for others it’s completing their first session, running their first kilometre or simply feeling more confident.

Mayhem has grown into far more than I ever imagined when I started it. I’m incredibly proud of the fitness community we have built and very grateful that I get to spend my days helping such a brilliant mix of people become fitter, stronger and more confident, while sharing plenty of laughs along the way.

Want to become a stronger runner without simply adding more miles?

Many runners focus almost entirely on running, but strength training can make a real difference. Building stronger glutes, hamstrings, calves and core can improve your power, help you maintain better form when tired and prepare your body for the demands of running.

At Mayhem, you can combine both in one evening:

18:00 Dumbbell Conditioning
19:00 Run Club

Whether you’re chasing a PB, building towards a longer distance or simply want running to feel better, both sessions can support your progress.

Come along for one or stay for both. All abilities are welcome, so drop us a message if you’d like to give Mayhem a try.

Since the inception! I have known Matt for years, so when he decided to start Mayhem, I was always going to join him on his next adventure.

2. What’s your favourite Mayhem session and why?

I have always loved the run class, but recently superhuman has been my weekly go to! I love seeing the strength we all having lobbing and pulling equipment.

3. What’s your favourite exercise, and which one would you happily never do again?

Carrying Thor hammer and I would happily never do a lunge again.

4. What’s your proudest fitness achievement so far?

Getting a sub 30 min 5km over 10 years ago, but now is watching my kids enjoy fitness like I do.

5. What do you enjoy most about being part of Mayhem?

The social side! You meet people with a similar interest and everyone is up for a giggle whilst working those muscles ( ). You don't have to be anyone but yourself.

6. What’s your funniest or most memorable Mayhem moment?

My funniest moment at Mayhem:

There has been many over the 6 years so I could not pin point just one.

My most memorable moment:

I will always love memories where people are laughing/smiling. Socials are always a great place to make more memories

7. What’s something most Mayhem members probably don’t know about you?

I played football for Rushden & Diamonds, MK Dons and Northampton Town before heading to University.

Another brilliant Sunday morning with the Mayhem crew!

We love being part of MK junior parkrun each week, and today we also enjoyed our monthly run with The Parks Trust.

It was fantastic to see so many Mayhem children and families out enjoying the morning together. The youngsters were brilliant as always, giving it everything, encouraging one another and, most importantly, having fun.

A special thank you to all the volunteers who make MK junior parkrun happen every week. They are always so welcoming, encouraging and fantastic with the children. Thank you also to The Parks Trust team for continuing to organise such enjoyable events for the local community. A lot of work goes into making mornings like this possible and it is really appreciated.

A huge well done to everyone who took part. A great turnout, plenty of orange shirts and another really enjoyable morning of running with the Mayhem community!
