My name is Tsvetomir (Adi), and I’m a certified strength and conditioning specialist and former yoga instructor (currently based in Copenhagen) with over 10 years of experience.
Through my work, I help improve the quality of life of my clients.
Who are my training sessions suitable for?
“If you have a body, you are an athlete.”
This quote from one of my favorite teachers guides my approach to training.
I work with modern-day athletes — in other words, anyone who wants to optimize their body using the latest proven methods for improving physical performance.
These can include:
Active individuals;
Professional athletes;
Older adults dealing with issues like poor sleep, trembling limbs, weak legs, and more;
Children who want to grow and develop in a specific sport.

What sets me apart?
My strength and conditioning sessions are grounded in the latest scientific research on physical performance and health through movement.
The results of my work are measurable — because “if you can’t measure it, it doesn’t exist.”

How I built my expertise
I’m a certified Strength and Conditioning Specialist through FC Barcelona’s academy (Professional Diploma in Strength and Conditioning), as well as a registered yoga instructor with Yoga Alliance.
I never stop learning — I continuously expand my education and stay up to date with the latest research in sports science and health-focused training.

Why did I leave yoga behind?
While teaching yoga, I spent years wondering why some clients weren’t seeing results — even though they trained hard and showed up consistently.
I searched for answers in many places, without success. That changed in 2022, when I started discovering the latest work by doctors researching elite athletes and top-level international coaches.
Their insights finally gave me the answers I was missing and opened my eyes to the most effective, science-backed ways to train.
Yoga simply isn’t among those methods.

1/ A strong body is a healthy body.
That’s why I focus on building and maintaining quality muscle. When we combine that with restoring our natural reflexes and proper nutrition, we help the body reach its best possible shape — at any age.

3 Fitness Myths — Busted
You want to start training (or train more), but something’s holding you back?
Let’s see if your concerns are truly valid — or just common fitness myths:
Women get bulky from lifting weights
No, if you're a woman, you won’t suddenly grow biceps like Princess Kalina’s just from hitting the gym 2–3 times a week.
What strength training will give you is better muscle tone and a more sculpted body that makes your clothes fit (and look) better.
Bonus: your health will thank you, too.

I’m too old to get in shape
It’s never too late to start training — because skeletal muscle is an organ that doesn’t actually age.
Yes, its quality declines when we neglect it, but the good news is: it can always be rebuilt.
And the benefits of doing so are huge — improved metabolism, faster reflexes, better mobility, balanced hormones, a stronger immune system… and much more.

I’ll lose weight by running
…or by starving myself, or with pills, or that special tea.”
If those methods actually worked, wouldn’t we all be fit by now?
The truth is, sustainable results come from smart training, proper nutrition, and consistency — not quick fixes.
Leave the strategy and planning to a professional. You just focus on showing up — and enjoying the results.

TESTIMONIALS
I am 56 years old and I had never done any kind of training before. A chance meeting with Tsetso, and I started. I couldn’t even open the elevator door—it was too heavy. I constantly felt tired. I recommend everyone to give it a try. Tsetsko puts his heart into fighting for us, even more than we do ourselves. He has a personal approach to each individual and achieves what is best for everyone. At first, I was exhausted after every exercise, but now I do them with ease.
IRINA
I am Tanya, a 66-year-old woman. I spent almost 40 of those years sitting in front of a computer for 8 hours a day. The result – back pain, stiff knees, swollen legs... In short – completely stiff. Training with Tsvetomir (I call him Tsetsi) showed me that where there’s a will, there’s hope. The exercises he designed for me are intense, yet balanced in terms of effort and relaxation. Not once have I had muscle soreness after a workout. I believe Tsetsi is a dream coach. Attentive and kind, he constantly encourages me to try new exercises, even if I don’t get them right the first time. He gives advice on proper nutrition. Thanks to him, I feel wonderful!
Tanya K.
I am extremely satisfied with Tsetso as a coach! Since he started training me, I’ve seen significantly better results and I feel and look better. He takes an individual approach to everyone, tailoring the training according to the person and their needs. He has a different way of thinking and always brings something new and different to the workouts, constantly keeping up with the latest developments in sports.
Emo S.
Training with Tsetso for the past 8 months at my home has transformed my fitness: I’ve significantly increased my strength and muscle size, lowered my resting hear rate, and boosted my VO₂ max. His friendly demeanor, positive motivation, and dedication to the latest evidence-based techniques make every session both effective and inspiring. I couldn’t recommend him more for anyone serious about achieving real results.
