ABOUT UNIT 54
Unit 54 is a unique and new revolutionary facility with its own style of indoor and outdoor training covering Hybrid and Functional fitness. We are a privately owned facility set on its own grounds in the beautiful countryside on the outskirts of Bath and Bristol.
We have created our very own style of fitness from functional strength and Olympic lifting, GRFT Full Gas cardio classes, Hybrid and Hyrox, GRFT Yard Work, and to top it off we have our very own Thermal Hot and Cold recovery centre.
We have moved away from the commercial gym environment so you can experience and enjoy fitness and reap the benefits whilst being part of an ever-growing member-based community. Unit 54 is like no other, and we facilitate all abilities from our Legends Classes down to our Mini GRFT’ERS!
THE OWNERS
MEET JOE, HEAD COACH
Yo! I’m Joe “Tux” Tucker, founder of GRFT Training, co-owner of Unit 54, father of five girls, ex-professional cricketer, and your head coach alongside my beautiful partner, Millie.
I spent nine years playing professional cricket, representing England U19 at World Cup level before injury ended my career at 25. Along the way I developed a passion for strength and conditioning, gaining qualifications in weightlifting, speed and agility, and coaching. On top of this, I've worked with some of the best strength and conditioning coaches in the world!
After running my own construction business for 17 years, I returned to my true passion, fitness. What started as a small “Studio 54” has grown into today’s Unit 54 GRFT Training Club, a full training and recovery facility where we help people of all levels achieve their goals.
Millie and I compete in Hyrox and endurance races, and together we’ve built a community focused on training smart, working hard, and enjoying the process.
That’s me - Coach Tux.
MEET MILLIE, MANAGER
Hi, I’m Millie, co-owner and manager at Unit 54, mum to five girls, fitness lover, and ex Police Officer.
Sport has always been part of my life. I’ve competed in hockey, netball, duathlons, Hyrox, and now focus on functional fitness, MTB, and running. I earned my Level 2 Coaching Qualification at 17 but chose policing as my career, proudly serving for 14 years on the frontline. Balancing shifts, family life, and fitness has been a challenge, but staying active has always kept me grounded.
At Unit 54, my role is Manager and Assistant Coach. I love structure and organisation — so I handle everything behind the scenes to keep the gym running smoothly. As a coach, I understand the struggle of fitting training around life, which is why we’ve built a place where showing up feels fun, supportive, and achievable.
Joe and I are not only business partners but partners in life, and together we’ve built Unit 54 into the incredible facility it is today. I’ve spent the past three years testing and progressing on the GRFT Training Club programme, and I’ve never had more fun with my training.
That’s me - Millie. Come and say hi, I’m always here to help!

CLIENT TESTIMONIALS
"After years of suffering with my weight and fitness I was looking for a gym to go to without feeling out of place. Luckily I found Unit 54. I would recommend any of the services that Unit 54 has to offer, purely based on how I feel in the gym and the level of support I have been given. If you’re looking for a supportive group of people to get you over the line to reach your goals then these are your people."
NATH
"2.5 years ago, after having a baby, I joined Unit54, and it’s honestly the best decision I’ve ever made. I’ve lost weight, toned up, and made amazing friends for life. The atmosphere is so friendly and encouraging, and our coach, Joe, is knowledgeable, approachable, and incredibly supportive. Unit54 isn’t just a place to train, it’s become my lifestyle!"
LOU
"Unit 54 has honestly changed my life, I didn’t enjoy exercising before joining. As I’ve lost more weight and become fitter & healthier, I now really enjoy it. I love pushing myself and feel incredible after a workout. I’m always talking about this gym. It’s an incredible community of people. Anyone can train at the big brand gyms, but this gym is so unique, also has an incredible supportive atmosphere."
