Numbers Never Lie
We are a results driven personal training studio in North London specialising in body transformations.
Client stories
From weight loss to muscle gain and an overall improvement in health, here are some of the before and after photos from men and women who achieved outstanding body transformations through BTX 1 to 1 personal training sessions at our private gym in Hampstead and online coaching.
Client results
The results you see on this page aren’t the product of extreme diets or punishing workout routines. They’re the result of a structured, data driven 12 week system that treats each client as an individual, with their own starting point, their own metabolism, and their own life to work around.
Every BTX transformation starts with an InBody 770 body composition scan. Not a weigh in. Not a pinch test. A medical grade measurement of fat mass, lean muscle mass, hydration, and basal metabolic rate, so we know exactly what’s happening in the body before a single session begins.
Results
Every transformation at BTX is built on 4 pillars:
Training: Periodised one to one sessions, progressing in load and complexity every 4 weeks. No plateaus. No repetition without purpose.
Nutrition: Habit based coaching built around your real life, not a meal plan that ignores your social schedule and food preferences. Sustainable, specific, and guided by your coach week by week.
Recovery: Sleep quality, stress load, and active recovery are monitored and coached. Most people underestimate how much recovery drives results. We don’t.
Accountability: Weekly check ins. Regular InBody rescans. A coach who is accountable to your results, not just your attendance.
What to expect
Results vary by individual, but across our North London client base, the patterns are consistent. In a 12 week programme, our clients typically lose between 5 and 12kg of fat mass (confirmed by InBody scanning), add between 1 and 3kg of lean muscle, and report significant improvements in energy, sleep quality, and daily performance.
Our most dramatic transformations have come from clients who had tried multiple approaches before BTX without success. The difference isn’t willpower, it’s the system. When training, nutrition, recovery, and accountability are all addressed together, results compound.
Who it's for
Our highest achieving clients share a common profile: they’re serious about their goal, they show up consistently, and they trust the process. They come from North London neighbourhoods including Hampstead, Belsize Park, Golders Green, Swiss Cottage, West Hampstead, Primrose Hill, St. John’s Wood, and South Hampstead.
They’re professionals in their 30s, 40s, and 50s, busy people who have made a deliberate decision to invest properly in their health. Some are returning to fitness after years away. Some are managing health conditions. Some have specific performance goals. All of them get a programme built entirely around their individual needs.

Inside BTX
An RMR test measures one number: how many calories your body burns at complete rest. It takes about ten minutes of lying still and breathing normally, and it replaces a formula’s estimate of that number with a measurement. Two things up front, before you read any further. We do not measure resting metabolic rate at […]
Keeping weight off after rapid weight loss is a different job from losing it, and the honest headline is that most people regain a substantial share of what they lost, but not all of it. Pooled across 48 studies and more than 3,200 participants, roughly 60% of lost weight was regained by 52 weeks after […]
If you want protein to maintain muscle while losing weight, the ranges the research actually uses are roughly 1.0 to 1.6 g per kg of body weight per day, spread across three main meals at 25 g or more each. That is the honest number. The honest effect size is smaller than almost anything else […]
