Body transformation coach for London.

Losing fat and building muscle takes sustained, consistent work, and London rarely gives you a long run without disruption. There will be busy periods at work, trips away and social weeks. JR plans your progress in phases, with periods focused on fat loss and periods focused on building, and sets each phase around what your calendar looks like. A heavy work month can be a maintenance phase instead of a failure. Weekly check-ins with weight, measurements and photos keep the direction clear, and the plan moves with you.

JR Coaching is online only. There is no studio in London and no in-person sessions: you follow your plan at your own gym or at home, and JR coaches you through weekly check-ins and messages.

Because it is online, it reaches every part of London: Westminster, Camden, Islington, Hackney, Shoreditch, Brixton, Clapham, Greenwich, Kensington, Hammersmith, Stratford, Wimbledon, and nearby Watford, Slough, St Albans, Guildford.

The phrase gets used loosely, so here is what it means with JR. It is a longer piece of work than a single diet or a single training block. The aim is to change how much fat and how much muscle you carry, and that rarely happens in one straight line. JR looks at where you are starting and decides what should come first. Someone carrying a lot of fat usually begins with a fat loss phase while lifting to keep muscle. Someone lean but undermuscled usually begins by building. Someone in between, or new to lifting, may be able to do both at once at maintenance calories, which is called body recomposition. Each phase has one aim, its own calorie target and a planned end, followed by a review.

Sometimes. Recomposition is most realistic for people new to resistance training, people returning after a long break, and people with more body fat to lose. In those cases the body responds strongly to lifting and can build muscle even without a calorie surplus. The method is not complicated: calories at or slightly below maintenance, protein high at roughly 1.6 to 2.2 g per kg of body weight, and hard, progressive resistance training. The scales may barely move while your shape changes, which is why measurements and photos matter more here than weight. For experienced lifters who are already fairly lean, doing both at once is slow. Separate building and fat loss phases usually serve them better, and JR will say so.

Body weight alone can mislead. You can lose fat and gain muscle and weigh the same, or lose weight and look no different because muscle went with it. So the weekly check-in uses several measures together. Weight is tracked as a trend. Tape measurements, such as waist and hips, show where change is happening. Photos, which are optional and private, show shape in a way numbers cannot. Your training log shows whether you are getting stronger, a good sign that muscle is being kept or built. And your own report on energy, hunger and sleep tells JR whether the current phase is sustainable. He reads these side by side. One measure going the wrong way for a week is noise. Several doing so is a reason to adjust.
