ABOUT ME
Who I Am
My name is Sergei.
I’m a certified personal trainer, posture specialist and movement coach with 10+ years of professional experience.
I don’t work with shortcuts, extreme methods or temporary motivation.
My coaching is built on structure, discipline and a deep understanding of how the body and mind actually function.
Over the past decade, I’ve worked with 300+ clients, online and in person, helping them:
-
lose fat
-
build lean muscle
-
correct posture
-
regain control over their body and habits
My focus is long-term transformation, not quick fixes.
PROFESSIONAL BACKGROUND
Before dedicating myself fully to coaching, I built and managed a network of travel agencies in Saint Petersburg.
That experience shaped how I work today:
systems, responsibility, leadership and long-term thinking.
Later, I lived and worked in Singapore as an international model and personal trainer.
High-performance environments taught me how stress, lifestyle, discipline and self-image directly affect physical health and body composition.
Today, I’m based in Amsterdam, working with an international client base.
INTERNATIONAL EXPERIENCE
I’ve coached clients from in person and online:
-
the Netherlands
-
Singapore
-
Russia
- and other countries
This gave me a clear understanding of how:
-
lifestyle and work routines
-
stress and sleep
-
cultural habits
-
nutrition patterns
impact posture, recovery and long-term results.
Because of this, no two clients follow the same program.
MY PROFESSIONAL APPROACH
I’m not just a gym trainer.
My expertise combines:
-
strength training
-
posture correction
-
mobility and flexibility
-
yoga, Pilates and TRX principles
-
recovery and nervous system balance
I also hold a professional massage therapy certification, which gives me a deeper understanding of anatomy, muscle chains, tension patterns and movement restrictions.
Posture correction and body alignment have been a core focus of my work for over 10 years and are fully integrated into the BST System.
COACHING & BEHAVIOR CHANGE
A large part of my work goes beyond physical training.
I work with clients who struggle with:
-
unhealthy habits
-
lack of discipline
-
emotional eating
-
long-term inconsistency
Instead of forcing motivation, I use structure, awareness and behavioral change.
We don’t just train the body.
We rebuild habits, routines and self-control.
That’s why results last.
NUTRITION AS A FOUNDATION
Nutrition is a core part of my system.
Up to 60% of body transformation depends on nutrition, not training volume.
My approach is:
-
adaptive, not restrictive
-
tailored to lifestyle and workload
-
adjusted for health conditions
I’ve worked with clients with type 1 and type 2 diabetes, where nutrition adjustments helped improve glucose stability under medical supervision.
Nutrition is not a template.
It’s a strategic tool.
MY MISSION
My mission is simple:
To help people build strong, healthy bodies through correct movement, posture, nutrition and discipline — and to show how deeply physical health affects confidence, mental clarity and quality of life.
This is not about aesthetics alone.
It’s about control, strength and long-term health.
THE NEXT STEP
If you feel your body deserves a smarter, more structured approach —
we can start with a conversation.
