How Paul Lost 43kg in Four Months with a Personal Trainer in Geelong
TL;DR: Paul hit 196kg after 15 years stuck behind a desk. A regular gym got him part of the way, but progress stalled at 168kg. He walked into Carbon Gym Geelong, started boxing with personal trainer Coach Rob, and dropped to 124.8kg in four months. That’s 43.2kg gone through boxing, personal training, a protein-focused diet, and a coach who actually followed up after every session. Here’s exactly how he did it.
Paul spent 15 years working 18-hour days at a desk. Six days a week. Barely moving. By the time he looked up from his screen, he’d hit 196 kilograms.
He knew something had to change. So he tried a regular gym. Walking. General weights. Over two years, he brought it down to 168kg. Then the progress stopped. The motivation started slipping. A normal gym just wasn’t cutting it anymore.
That’s when he found a personal trainer at Carbon Gym in North Geelong. Four months later, he was 124.8kg. He’d lost 43.2 kilograms. And for the first time in his life, he was happy waking up at 4am.
This is Paul’s story, in his own words, and the science behind why it worked.
How Did Paul Lose 43.2kg in Four Months with a Personal Trainer in Geelong?
Paul lost 43.2kg in four months by combining boxing sessions with personal training, prioritising protein-rich meals, and training twice a day with his coach Rob at Carbon Gym Geelong. The key wasn’t one magic exercise. It was having a coach who built a plan, mixed things up, and held him accountable every single day.
When Paul walked through the door at 168kg, Coach Rob didn’t throw him into the deep end. They started with boxing. Pad work, technique, footwork. Then they layered in weight training to keep things interesting.
“We not only concentrated on boxing but also a bit of weight training at the same time,” Paul said. “Which basically made it easier to not get bored. A little bit of this and a little bit of that.”
That variety matters more than people think. Boxing alone can burn between 500 and 1,000 calories per hour depending on intensity and body weight. For someone Paul’s size, those numbers were even higher. A study referenced by Harvard Medical School found that a 70kg person burns up to 800 calories in an hour of intense boxing. Paul was training at well over twice that body weight, pushing serious energy output every session.
But the calories were only part of it. The real difference was consistency, and that came down to the coach.
Why Did a Normal Gym Stop Working for Paul?
A normal gym stopped working because Paul had no accountability, no structured program, and no one checking in on his progress. He was doing it alone, and at 168kg, the motivation to push through a plateau wasn’t enough on its own.
This isn’t unusual. Research published in Heliyon found that only the group trained by a personal trainer showed measurable fat reduction compared to baseline. People training solo or even in groups didn’t see the same results.
It gets more specific than that. A survey by the American Council on Exercise found that 95% of people who work with a personal trainer report higher motivation, and 80% are more consistent with their workouts. Having someone in your corner changes the equation entirely.
Paul felt that difference immediately.
“The initial struggle was committing myself to do something and wanting to do it long term,” he said. “I just needed to find the right person.”
He found that person in Coach Rob.
The Coach Who Made the Difference
This section isn’t about boxing technique. It’s about the human stuff that actually makes people stick with training.
Paul needed someone he clicked with. Someone who felt like a mate, not a clipboard.
“Personality wise, he was like me,” Paul said about Rob. “Simple, easy to get along with. We had a lot of things in common. I found it very easy to work with him in terms of teaching me what to do, when to do it, how to do things, and also motivating me.”
But the bit that really stood out? The follow-up.
“He’s always contacting me after I leave the gym to see how I’ve gone,” Paul said. “Whether I’ve got any injuries, any motivational issues. Just those little things where he’s concerned about how I’m training. The follow-up made it even easier to want to keep coming in more and more.”
That kind of accountability isn’t just nice to have. Studies show that having an accountability partner can increase weight loss results by 50 to 60%. And clients with external accountability are 65% more likely to reach their fitness goals.
Coach Rob didn’t just train Paul. He built a relationship where showing up became the easy part.
If you’re looking for that kind of personal training at Carbon Gym, that’s exactly how our coaches work. It’s not a one-size-fits-all template. It’s built around you.
What Does a Typical Day Look Like for Paul at Carbon Gym?
Paul trains twice a day, seven days a week, fitting boxing sessions around a full work schedule. His typical day starts at 4am and includes a 90-minute double session at 5am, a 45-minute session at midday, and two walks with his dog.
Here’s how he breaks it down:
“I wake up at about 4am, get ready by 4:30, and I’m at boxing by 5am. I’ll do a double session with Rob, around 90 minutes of intense workout. Then I go home, walk my pup for 30 minutes, shower, and start work by 8:30.”
“Around 12, I’ll come back for another 45-minute session with Rob. After that, another hour walk with my pup. Then back into work till about 6 or 7.”
That’s three to four hours of physical activity a day. For a bloke who spent 15 years barely leaving his desk, that’s a complete 180.
And the energy? Better than ever.
“I only sleep about three to four hours a night. I’ve done that for 20 odd years,” Paul said. “But through the physical fitness and boxing, I don’t get tired at all.”
You don’t need to match Paul’s schedule to see results. If you want to see what session times work for you, check the timetable and find something that fits.
Can a Desk Job Really Make You That Unhealthy?
Yes. Prolonged sitting is one of the biggest risk factors for obesity, heart disease, and early death. Paul’s story is a textbook case of what happens when a sedentary job goes unchecked for over a decade.
Paul worked a desk job for 15 years, 18 hours a day, six days a week. Minimal movement. Meals at the keyboard. He hit 196kg.
The research backs up exactly what happened to him. A study reported by CNN found that people who predominantly sit at work have a 16% higher risk of dying from any cause, and a 34% higher risk of cardiovascular death. Research published in the Journal of Environmental Research and Public Health found that for every two-hour increase in sitting time, the risk of obesity rises by 5% and diabetes risk by 7%.
Paul knew it was happening. He just couldn’t break the cycle.
“I got bogged down with work,” he said. “I let work take control of my life. When I was younger, I thought I had plenty of time to sort it out. As I got older, I realised you just can’t put a price on health. If work has to come second, so be it.”
That mindset shift, putting health before the desk, is what made everything else possible.
What Did Paul Eat to Lose 43kg?
Paul followed a high-protein diet focused on whole foods: chicken, turkey, eggs, salmon, vegetables, and protein shakes. He didn’t follow a strict meal plan or count every calorie. He simply made protein the priority at every meal.
Here’s how he described it:
“Every morning I’ll have some form of protein. Chicken, turkey, eggs. Mid-afternoon, maybe a protein shake. Dinner is veggies with some kind of meat: red meat, chicken, turkey, sometimes seafood. I love my salmon.”
Simple. Repeatable. Sustainable.
And the science supports this approach. A clinical review published in Nutrients found that high-protein diets reduce body weight and decrease fat mass while preserving lean muscle, especially when combined with resistance training. Another study in the American Journal of Clinical Nutrition showed that the higher-protein group gained about 1.1kg of muscle even while in a calorie deficit, while the lower-protein group gained none.
For Paul, the combination of boxing, weight training with Coach Rob, and protein-heavy meals meant he was burning fat and building muscle at the same time. That’s a difficult thing to do without the right training and nutrition working together.
“Probably the Best Thing I’ve Ever Done”
Those are Paul’s words. And he means them.
He came to Carbon Gym Geelong at 168kg, discouraged, and stuck. Four months later, he’s 124.8kg. He’s training twice a day. He’s prioritising his health over his desk for the first time in his life. And he’s nowhere near done.
“I’ve surpassed my goals,” Paul said. “I’ve got a long-term plan now. Even though I work long hours, I still treat this as my number one priority.”
His advice to anyone thinking about getting started?
“Get off the couch. Commit yourself and say, I’m going to change my life. Come into Carbon Gym, speak to the trainers. They made me feel welcome. It was the best move I ever made.”
