Dr Steve James · Highend executive coaching
I’ve worked as a consultant in critical care, exercise testing, and managing fatigue. More than 90% of the patients I’ve cared for are in hospital with preventable disease and the current healthcare system is not going to fix this problem for you, me or society.
Medical school and specialist training didn’t teach me or other doctors how to help people be healthy. Healthcare looks at issues in isolation and is reactive. So I went on my journey, learning about health from many perspectives.
Metabolic dysfunction or disease became a common theme. It was behind heart attacks, chronic fatigue and dementia as well as diabetes and obesity. No one I knew in healthcare was looking at it. I learnt more about mitochondrial health, glucose metabolism, body composition and ketogenic diets.
Taking a broad approach to health has helped my clients not just change their numbers but change how they feel about life. They have lost fat but not muscle, sleep better and have more energy. They are going to live longer better lives and prove that illness and disease are reversible.
Health programmes
A personalised day of in depth testing using cutting edge science at leading medical facilities. At home sleep studies, glucose monitoring and a functional strength assessment. Comprehensive on boarding. Dr James will take time with you to review your results either in person or on a video call. You will develop a clear understanding of what really matters in your health.
To guarantee results our Health Programmes support the change you want by continuing on from a Health Assessment. One to one support through consultations and weekly check ins with Dr Steve James. Structured guidance on how to improve your sleep, stress and nutrition. Personalised training and supplement recommendations. All the key elements you need for success in health.
The approach
Disease develops over decades and can be detected at a variety of different stages. The early stages in particular, before scarring or fibrosis have occurred, are also reversible.
Look in depth at your total health so that you can intervene early and make changes. Steer towards health by heeding the early warning signs.
Let’s establish a relationship where you are known. Where you have an understanding of what will drive your health. Where you are empowered to adapt and reap the benefits.
Let’s find the troublesome patterns and your unique opportunities to change. Let’s prioritise for the biggest wins and bring about the most long lasting results. Let’s do it in a way that puts your emotional and cognitive health centre stage.
Your experiences and current life are unique, so a health programme needs to be tailored to your bio individuality. What works on average for a population isn’t necessarily the optimal treatment for you.
Recognise the strengths and weaknesses of applying leading edge research to your life. Respect your individual experience. Weigh up the benefits and drawbacks of interventions in the context of the whole person.
Evolutionary adaptation means our body can respond to particular stimuli with repair, recovery, growth and health. Our biology is inherently intelligent and geared to protect us from harm.
We are working together with market leaders in healthcare. Testing can be arranged locally for wherever you are in the world. Consultations are over video call or in person in London. All notes are kept on a secure electronic patient record that is GDPR compliant.
FAQ
Still unsure if BTX is right for you? Ask us directly. We reply fast on WhatsApp.
Online Coaching is ideal for individuals with a year or more experience lifting weights already under their belt. If you are new to the weight room, then it is vital that you seek 1 to 1 in gym personal training in order to learn the correct form and technique first.
If you do have experience, but need a plan that can generate long and lasting body transformation results, then this could be for you. Online coaching takes the guess work out of your training, habits, nutrition and recovery under the watchful eye of our top rated personal trainers.
The world of exercise science is vast and constantly growing. Our top rated team of personal trainers keep up to date with the latest in nutrition, weightlifting and exercise science in general, so we can apply the latest principles to help our clients.
Lastly, the Kaizen Warrior, our personalised online coaching is VERY different to an average online programme you’ll find on the internet. The latter often provides no ongoing support or assistance. At BTX, we’re proud to provide continuous help and advice to our online clients.
Your BTX online coach will hold you accountable, adjust your training and / or diet when needed and help you achieve your specific goals together.
We’ll choose a personal trainer that we think will be best suited to your individual case, however, if you feel compelled to ask for a specific coach from our personal trainers team, we are very happy to accommodate your choice (subject to availability).
Yes, for your online coaching sessions you will need a gym membership or access to gym equipment.
This is all down to 2 factors. Your compliance with our strategy for your body transformation and your genetics. We expect our clients in a fat loss phase to average between .5 to 1kg of weight loss per week, while with our bulking phase we aim for .3 to .5 per week of muscle gained. Check out this gallery of incredible body transformations from BTX clients to see what results you can get by training with us.
The key difference is the method of delivery. While online coaching is done remotely, our in person coaching involves 1 to 1 sessions at our Hampstead personal training gym. Both methods have their advantages and disadvantages; for example, online coaching offers more flexibility and convenience, while in person coaching may allow for more nuanced interaction.
Our onboarding process will clear up all dietary requirements so that we can best advise you on a plan that suits you best.
Yes, we will provide you with our best protocol to make sure you can still enjoy a night out without throwing away your hard earned progress.
Our Kaizen Warrior online coaching package includes:
Online coaching with BTX works through a combination of video conferencing, phone calls and emails. Your dedicated online PT will work closely with you on implementing a bespoke training programme that suits your goals and your lifestyle. as well share resources such as worksheets or pre recorded videos so you can work on your own and do weekly check ins to monitor your progress.
We hold our clients accountable with personalised targets and check ins every week for the Online Kaizen Warrior programme.
We’re here to help so you can contact us via agreed messaging platforms and at the times suitable for both your online coach and you. We will discuss specific terms during our first session.
You will. It will be a calorie and macronutrient counted list of all the foods (and the quantities) you can eat daily, while remaining within the parameters we set up for you.
Yes. We will guide you on the specifics in person, but we always allow our clients to lead as normal of a life as they can as the only transformations we are interested in are the sustainable ones. There would be very little point in coaching someone to do something that they can barely get away with all year round.
Our PTs will track your workouts and progress with your personal folder which contains your workout, updated workout log, updated scans. We also have a client success meeting weekly to discuss our client’s individual results and strategise (should we need to) on how to forward the transformation as quickly as possible.
No. Rest is a vital part of growth and recovery, without which you can never see any measurable results. The amount of resistance training sessions we assign is down to the individual’s goal and experience level
