Your first visit includes an InBody body composition scan and a full movement assessment. If you have injuries, a medical condition or specific guidance from a physiotherapist or GP, the programme is built within it from the start.
Personal trainer St John's Wood
St John’s Wood is a neighbourhood that takes quality seriously, from the houses around Abbey Road to the turf at Lord’s. Choosing a personal trainer St. John’s Wood residents can genuinely rely on should be no different.
At Body Transformation London (BTX), we coach professionals, parents and retirees from NW8 at our private studio on Finchley Road, a few minutes away by car or bus.
This page explains how we work, who we work with, and what you can sensibly expect from coaching, so you can decide whether we are the right fit before you ever pick up a dumbbell.

Your coach
Plenty of trainers can make you tired. Far fewer can make you measurably stronger, leaner and more mobile over months and years while your career and family life carry on around you. When you assess any coach, in our view you should look for 4 things:
Clients from St Johns Wood usually arrive with high standards and very little spare time. Our job is to make every one of their training hours count, with a programme that is measured, progressive and honest about what it takes.
JamesBTXThe BTX method
Your first visit includes an InBody body composition scan and a full movement assessment. If you have injuries, a medical condition or specific guidance from a physiotherapist or GP, the programme is built within it from the start.
Sessions are one to one or small group at a private studio, so there is no queueing for equipment and no crowd. The core of most programmes is progressive strength training, supplemented with conditioning, mobility and, where useful, the coordination work described in our neuro athletic training guide.
Nutrition coaching at BTX is practical: protein at most meals, mostly whole foods, portions matched to your goal. It accommodates restaurant lunches, family dinners and the occasional interval at Lord’s, because a plan you cannot live with is not a plan.
Every BTX programme starts with an InBody body composition scan and movement assessment, so we know exactly where you are before we map out where you’re going.
Who it's for
3 groups make up most of our NW8 client base:
Whatever the starting point, the standard we hold ourselves to is the same: training that is safe, measured and worth your time. The NHS physical activity guidelines, 150 minutes of moderate activity plus 2 strength sessions a week, are the floor we build from, not the ceiling.

Good coaching is mostly good listening. Before we talk about sets and reps, we want to know how you sleep, how you work and what your week really looks like. The plan comes from that.
GiuseppeBTXResults
We will not promise you a specific dress size or a number of kilos by a certain date, because no honest coach can. What we can say is that clients who train consistently with us typically feel more energetic within weeks, move noticeably better within a couple of months, and build strength and body composition changes that compound over the months that follow. Progress is tracked openly, scan by scan and session by session, so you always know whether the plan is working.

Yes. Many clients combine studio sessions with online programming for travel weeks, and some train with us fully online with the same assessment first approach.
Very much so, provided we start conservatively. Strength and balance training are among the most valuable things you can do at any age; we will progress carefully and involve your GP where appropriate.

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 […]
