Hey, Champ.
I'm Trey.
Just Trey Personal Training provides private 1 to 1 personal training and performance coaching, specialising in strength, boxing, kettlebell training, mobility and physical conditioning.
The philosophy
A strong foundation
is everything.
My approach is built on the belief that a strong foundation is the most important part of training.
Before focusing on advanced techniques or greater intensity, clients learn how their body works, how to move correctly, how to execute exercises safely and effectively, and how to develop the mobility, control, strength and awareness needed to progress.
That foundation becomes the platform from which more advanced skills are developed — whether in strength training, boxing or kettlebell work.
I work with people of all ages and experience levels, from complete beginners to experienced athletes. Every client is different, which is why every programme is individually designed around their goals, experience, lifestyle, movement, physical abilities and the direction they want to take their training.

Specialisms
What I coach.
Strength, boxing, kettlebell training, mobility and physical conditioning — individually, or combined into one programme.
Strength
Stronger movement first. More load second. Strenght build progressively and with purpose.

Technique, footwork, pads and conditioning, with practical self-defence skills where appropriate.
Kettlebells
Swing, clean, row, press, pull and carry - taught properly and progressed with control.
Mobility & conditioning
Better movement, greater control and the conditioning to support everything you do
Beyond the physical
Training is not only
physical development.
I teach respect for the body, discipline, consistency and the mindset required to make meaningful, long-term progress.
Stronger and more capable
Physically, but also in the sense of knowing what your body can do and how to look after it.
Confident and knowledgeable
Clients finish every session understanding more about exercise and training than when they started.
Habits that last
Routines that support a healthier, more active life long after any single programme ends.
Who I work with
All ages.
All experience levels.
From complete beginners to experienced athletes. Every client is different, so every programme is different.

Real people. Real progress.
I used to feel completely out of place…
I used to feel completely out of place around weights, but everything was explained clearly and without judgment. I've since lost 12kg (26.5lbs), can finally see my abs, and feel stronger, fitter, and more confident than ever.

Training experience
For me, the breakthrough was consistency. I already knew exercise was important, but I struggled to stick with it. Having structured sessions and someone keeping me accountable finally changed that.
Stevie C • Trustpilot
Unmatched coaching
I appreciate being pushed when I need it but also having sessions adapted when necessary. That balance has helped me progress consistently. If you wanna improve big time Tray will make sure you get far beyond where you wanna be!
VLAD • Trustpilot
This feels sustainable
That's probably the biggest difference from everything I've tried before. I'm making progress, enjoying training and don't feel like I'm counting down until the programme ends.
