MY JOURNEY

My Way to Transformation

01

Early Foundation

Kickboxing from age 6, then water polo, rugby, and football built my physical and mental base: discipline, resilience, and consistency. And from the age of 16, I began my path in strength training.

02

Natural Bodybuilding in Ukraine

In 2021, WNBF Ukraine was founded - the official representation of the World Natural Bodybuilding Federation (WNBF). Since then, Ukrainian athletes have had the opportunity to participate in international tournaments, competing under fair conditions and a two-level doping control system.

03

Neptune’s Way Coaching

My concept is Neptune’s Way: a personal journey through life’s waves toward strength and freedom. My coaching follows the same model: system, accountability, aesthetics, and progress.

Stories from clients and athletes who trained with me through lifestyle change, contest prep, and long-term transformation.

"Our cooperation has already lasted two years and continues further. At first, I reached out with a hernia issue, which after starting work with David has not bothered me even once! Then we moved on to preparing for natural bodybuilding competitions. This is the coach who turned my life upside down, opened new opportunities, and showed me what I am truly capable of!"

"In August 2024, I started working with David and continue to this day. I was looking for a good mentor for my debut in natural bodybuilding competitions. We work online, and both David's work and mine are carried out clearly. Thank you for the valuable knowledge and experience. We keep moving forward!"
