If you’re in London on a private prescription for Ozempic, Wegovy or Mounjaro, you’ve probably noticed the same thing most of my clients noticed. When the prescription arrives, you get an app sending you reminders to inject, a recipe for overnight oats, and a library of 20-minute bodyweight workouts. That’s the entire support package most of these platforms throw in.

If you’re searching for a personal trainer for Ozempic, Wegovy or Mounjaro in London, you’ve usually started from this point. The drug is working and the weight is coming off, but something about the plan still doesn’t feel like enough, and most of the time it isn’t.

The Standard Package Is Mostly an App

Since 2023 a long list of UK online pharmacies have started prescribing these drugs. Juniper, Habitual, Manual, Superdrug Online Doctor and plenty of others are all in this market now. The "coaching" most of them throw in is almost entirely app-based: habit-tracker prompts, generic meal plans, and easy bodyweight workouts designed for your living room. Some platforms bundle in a PureGym or Hussle membership. None of them, that I’ve seen, actually give you a coach who programmes your training around the drug you’re on.

For most users that’s fine at the start. The novelty of the drug and the early weight loss carry things for a while. It’s around month three or four when the problem starts to show up in my inbox. New clients come to me lighter than they were but weaker than they expected, a bit lethargic, losing interest in the gym, and starting to worry about the body composition underneath the number on the scale. At that point they go looking for specialist help and realise the options are thin on the ground.

The Coaching Gap

The NHS rules on prescribing Mounjaro (NICE TA1026) actually say you should be getting at least nine months of proper lifestyle support alongside the drug, including real nutrition advice and real coaching on changing your habits. Private prescribers don’t have to follow that, and almost none of them do at the level my clients need.

The drug is easy to sell, proper one-to-one coaching is expensive to run, and most of these companies just skip the second bit.

So what most people on a private Mounjaro or Wegovy prescription end up with is a powerful drug and a one-size-fits-all template, where the drug does all the weight loss work and the template does almost nothing to protect your muscle, build a real training habit, or prepare you for the prescription stopping.

That’s the gap specialist coaching fills. Turning weight loss on a drug into a real, lasting body composition change is a different job from prescribing the drug, and at the moment, it’s nobody’s job.

Coaching Around the Dose

Coaching someone on Ozempic or Mounjaro isn’t the same as coaching a general fat loss client. Three things differ in ways that change how the programme is built.

Training has to be programmed around the dose cycle. Nausea and stomach upset peak in the 24 to 48 hours after injection. That’s a bad window for a heavy training session. Days three to six of the weekly injection cycle tend to be the productive training window. A standard "three sessions a week" plan that ignores the cycle will give you sessions where you feel terrible and quit early, convinced you’re not cut out for the gym. That’s a timing problem, and it’s solvable in about ten minutes once you know to look for it.

Nutrition shifts from "eat less" to "protect protein." People on these drugs naturally eat less without being told to. The drug cuts how much you eat by 16 to 39%, and plenty of people drop below 800 calories a day in the early weeks without realising. The coaching question changes from "how do we get you eating less" to "how do we get 120g of protein into you when you can barely face food." That’s a different conversation, and it doesn’t map onto standard fat-loss meal plans.

Body composition matters more than the scale. Two people who lose the same 15kg on Mounjaro can end up with very different bodies depending on how much of that weight was muscle. In the big Mounjaro trial (SURMOUNT-1), the average split of what people lost was roughly 26% muscle to 74% fat. But across different studies, the muscle loss has ranged from 15% to 60% of total weight lost, mostly depending on how much protein people ate and whether they were lifting weights. You need to track strength, take waist measurements, and ideally get a body composition scan now and then (DXA or InBody), not just step on the scale.

The Injection Week

A typical week for one of my Mounjaro clients injecting on a Sunday looks something like this:

  • Sunday (injection day): no training planned. Focus on hydration and easy-format protein like Greek yoghurt, cottage cheese, or shakes. A walk if they fancy it, nothing more.
  • Monday: rest or light walking. This is the peak-nausea window and training here is a bad idea for most people.
  • Tuesday to Friday: three full-body resistance training sessions. Compound movements, RPE 6 to 7 during dose escalation, progressive overload from maintenance phase onwards. Roughly 10 working sets per major muscle group across the week.
  • Saturday: low-intensity cardio or recovery movement. Nothing that compromises the coming week.

That’s a specialist schedule, and it isn’t something an app handing out 20-minute bodyweight circuits can produce. Honestly it isn’t complicated once you know what you’re doing. The problem is, almost nobody in the standard prescriber-plus-app setup does it.

If you want the detail on how the protein and training side fits together, here’s the full guide to keeping muscle on Ozempic.

In-Person in London, Online Anywhere

Specialist GLP-1 coaching isn’t right for everyone. I mainly work with:

  • People on a private prescription for Mounjaro, Wegovy or Ozempic who want to protect their muscle and build a long-term training habit
  • People three to six months into treatment who are starting to think seriously about coming off the prescription
  • People nearing the end of their prescription who want a structured plan to come off without regaining everything
  • People who’ve already lost significant weight and now want to actually build muscle on the new, lower bodyweight

If you want a generic meal plan and some cardio guidance, plenty of platforms can give you that. What I do is one-to-one, specialist, and built around the drug you’re on.

I’m based in Southeast London and I coach both in person and online. The in-person work tends to be with local clients who want hands-on sessions at the start of a programme, especially if they’re new to lifting. Once technique is solid, most move to a blend of self-directed training with programme updates and weekly check-ins. That keeps coaching sustainable for busy professionals who aren’t looking to spend four hours a week commuting to a supervised session. Online clients across the UK get the same programme structure, weekly check-ins, and injection-day adjustments.
