🩺 Coach, not doctor
I’m a fitness coach, not a medical doctor. Everything on this site is educational. If you have a health condition, take medication or have symptoms that worry you, please see your doctor first. I’ll always tell you when something needs a medical check. (“FitWithDrSam” is just the brand name.)
My story: from 91 kg to 80 kg
I wasn’t born into fitness. There was a time I barely recognised myself in the mirror. I’d let myself go, I felt sluggish and stuck at 91 kilograms, and I’d half convinced myself that this was just who I’d become.
Like most people, I went looking for answers online: YouTube, Instagram, X and every fitness blog I could find. I bought equipment I didn’t use. I trained at home, then joined a gym, and for a long time I didn’t really know what I was doing. What I did do was keep showing up. When I finally saw the results of that consistency, I fell in love with the process.
Losing those 11 kilograms was never just about a smaller size. It was about building a stronger, healthier version of myself, and it was only the start. I had to learn how to eat for training, stay disciplined and build real strength. That’s where I learned that fitness is a marathon, not a sprint, and why consistency beats intensity.
“Consistency beats intensity. Keep showing up and the results follow.”
Why I believe in guidance
At some point, determination wasn’t enough. I started working with a personal trainer and a nutritionist, and it was the best decision I ever made. My trainer taught me how to structure my workouts and, just as importantly, reminded me I was capable of more than I thought. My nutritionist showed me that eating well isn’t about restriction. It’s about fuelling training and recovery: balancing protein, carbs and fats, eating around workouts and staying hydrated.
I know how it feels to be confused, overwhelmed and stuck. That’s why I coach: so you don’t have to learn everything the hard way like I did.
Why I started this website
When I began, I saw endless misinformation online: crash diets, quick fixes and plans that never delivered. I started posting on X as a training diary, and as more people found it useful, I began sharing full workouts, the science behind exercises and diet myth-busting. Tweets weren’t enough for that, so I built this site: one place with full guides, complete plans and nutrition advice, checked against real research.
How I coach
As more readers asked for personal help, I trained formally as a fitness trainer and moved from sharing tips to coaching clients one to one. My approach is simple:
Evidence first
Plans are based on current research and official guidelines, not trends.
Built around you
Your training history, lifestyle, schedule, food preferences, health and goals come first.
Safe & sustainable
A balanced mix of strength, cardio and mobility you can actually keep doing.
Food that fits
Calories, protein and simple meals you enjoy, with swaps and a shopping list.
Honest about limits
If something needs a doctor, I’ll say so.
Progress you see
Clear steps and simple tracking so you know it’s working.
