My name is Petar Vrečko, fitness trainer and nutritionist. What sets me apart from others is a unique approach to body transformation – I combine knowledge in fitness, nutrition, and modern technology through 3D body analysis, the only one of its kind in Croatia.
Through years of experience, I’ve learned that success doesn’t happen overnight, but through a smart plan, motivation, and support. My goal isn’t just for clients to lose weight or build muscle, but to teach them how to adopt a healthy and sustainable lifestyle that lasts long-term.
As a coach, I’m known for my empathy and ability to listen – because I believe everyone is unique and deserves a personalized approach tailored specifically to them.
If you’re looking for a coach who will show you the way, and walk with you every step of the journey – I’m here to help.
The first step toward change – we get to know your goals, habits, and challenges, and together we build a plan that suits you, whether we work online or in person.
A detailed picture of your current condition – we reveal your body fat percentage, muscle mass, and other key data that give us a solid foundation for progress.
Practical and personalized training and nutrition plans – step by step, I guide you toward better health, strength, and energy.
Visible transformation, but also inner satisfaction – because success isn’t just in the numbers, but in how you feel every day.
Whether you want to lose weight, get stronger, gain muscle mass, increase your energy, or simply feel more confident in your own skin, I offer individual packages designed to transform your life.
I offer short-term collaborations as well, but my 3+ month packages deliver the most significant results. During that period, with full guidance and following my program, most clients manage to lose between 5 and 15 kilograms or gain strength like never before.
Results depend on consistency and individual habits, but with my plan and your discipline – change is inevitable.
For additional requests (family discounts / multiple people, etc.) or longer collaboration periods, we agree on new prices after the consultation. The longer the collaboration – the better the price. All service prices are available under “Info” → “Prices”. Contact me for more details .
The first meeting includes a conversation about your goals, habits, and previous experience. Then we do a 3D body scan to get an accurate picture of your condition and create a truly personalized plan.
A 3D body analysis is a detailed digital representation of your body that precisely measures proportions, posture, and changes over time. It allows you to see progress that a scale can’t show, and gives me the data I need to create an even better and more accurate plan.
Yes, absolutely. My approach is based on empathy and adaptation. The program always starts at your level — without pressure, without forcing, and at a pace that suits you.
The nutrition plan is simple, sustainable, and tailored to your habits, tastes, and goals. There’s no starving and no strict diet — you eat the food you enjoy, with smart adjustments.
Yes — I’m available to you every day through the web app and messages. You can ask me anything you need: advice, motivation, plan adjustments, or progress check-ins.
You get:
-personalized training plans
-video workouts and demonstrations
-an individual nutrition plan
-progress tracking

The plan is adjusted every 2–4 weeks, depending on your progress. If needed, I can change it earlier — communication is quick and easy.
You can still work with me. I adapt the program to your abilities, limitations, and your doctor’s recommendations. Your safety is always my top priority.
I do both.
In person: Opatija and Rijeka.
Online: through the web app, video workouts, and regular communication.
The results are just as good if the program is followed.
It depends on your starting point, goal, and consistency. The first changes usually appear within 2–4 weeks, and the 3D analysis will clearly show every bit of progress.
You can use the 3-month package within a maximum of 5 months from the start of the cooperation.
This gives you extra flexibility in case of injury, travel, illness, or any unexpected reason that prevents you from training for a period of time.
