Dedicated to Better Movement & a Sustainable Weight Loss

In almost ten years as a trainer, I have worked with a wide range of clients. This includes busy parents looking to shred fat, world champion athletes and anyone in between. This experience, along with my extensive education,  has enabled me to excel in the following areas:

  • Weight Loss 
  • Mobility & Motor Control
  • Athletic Movement

The fitness industry has a lot to answer for. Despite the abundance of commercial gyms, it is more daunting than every to get involved in fitness. I wish to change this by helping my clients feel motivated, capable and confident, as they finally achieve their fitness aspirations.

The best way forward is individualization. Wherever you’re a personal training client or apart of my online mentorship, your plan will suit your goals, your ability, the time you have available and your preferences.

Personal Training

Build your gym confidence whilst mastering exercise and nutrition. This programme is ideal if you're looking to get the most out of every rep. I'll be walking you through the integrate details of every technique.

Online Mentorship

Having a trainer at your side may not be right for you. Or perhaps you're from a far away land. Either way, I will create your customized training and nutrition protocol. Furthermore, I'll be checking in frequently to make sure that you're on track.


Looking to give your team that winning edge? Or maybe you're a group of runners looking to smash your next personal best. My biomechanics workshops are second to none.


In-depth information about my coaching practice.

I don’t do a “one size fits all” kind of programme. We’re all different. We all need different training plans, specific nutritional needs and various levels of support. Until we discuss your needs, I am unable to offer you a price.

Most coaches only focus on diet and exercise. They fail to see the importance of stress management, sleep and what we do when we’re away from the gym.

I take a holistic approach and treat each client as an individual. This means…

  1. Training plans will be specifically created for you – instead of being pulled from a generic template.
  2. You can contact me between sessions – I won’t leave you hanging high and dry.
  3. I help you to elicit a permanent change to your psyche – so that you may sustain your new body.

I offer Personal Training at the following address:

JD Gyms Swansea, 3, Glamorgan, Parc Tawe North, Retail Park, Swansea SA1 2AL

If this venue doesn’t suit you, you may wish to consider my Online Mentorship.


Not at all. I’ve coached clients from across the globe via my Online Mentorship. Please note – all coaching is conducted in the English language.

The Online Mentorship is a virtual training experience which includes:

  • A Personalised Training Regime
  • Nutrition Coaching
  • Consistent Support via Direct Messenger

This is the perfect platform for those who feel technically competent in the gym but wish to level up their knowledge and results. 

I love working with beginners! This gives me the opportunity to make them feel 100% confident with their exercise and nutrition. No matter where you’re starting from, it’ll be my pleasure to simplify things for you.

Since starting my career in 2011, I’ve worked with elite academy athletes and world martial arts champions. Maybe you already know what you’re doing and you want to take it to the next level. I’ll keep you on track and teach you some new things along the way.

This completely depends on your goal and your current circumstances.

As a standard bench mark, many of my clients see an outstanding physical transformation in 8 weeks. Research would suggest that clients who stay with me for 180 days would be more lightly to sustain their results.

A typical Personal Training session lasts 1 hour.

This includes 45 minutes of exercise followed by 15 minutes of managing your nutritional needs (this is subject to the clients needs).

Yes. Many people have approached me with pesky spine, shoulder and knee injuries and we’ve managed to work around them just fine. However, if I feel that medical attention would suit you better, I will do my best to guide you to a great practitioner.

I hate cookie cutter programmes.

Each programme I design must meet the clients physical needs, diet preferences, personality and time commitment. For you to understand the customization that goes into my planning, here’s a few examples from the past 10 years.

  • A 78 year old gentleman who wanted to improve his flexibility as he could no longer put his own socks on.
  • A lady with a neck injury who’s limited to body weight exercises as she was staying in a hotel.
  • A 17 year old football player training to earn a soccer scholarship in the USA.
  • A World Taekwondo Champion wishing to improve his strength without putting on extra weight.

Whatever your circumstances, I have your back!
