The KOUDSTAAL Mission

We strengthen body and mind through rational, effective, and safe training. KOUDSTAAL helps you reach your highest potential — clear, focused, and without noise.

The KOUDSTAAL Vision

Human beings are responsible for their own lives. By setting rational goals and continuously pursuing them through physical and mental development, self-worth grows — and with it, lasting fulfillment.

What does it mean to choose yourself? You take your life and health seriously because you understand that your future and happiness depend on it. You are a unique individual who strives to become your best self, because life is about growth and flourishing. Welcome to Koud Staal personal training.

LENNERT

“Every HIT training is basically your own heroic fight. If you go for it, you always win, because you turn out to be stronger than the time before.”

Perfectly tailored training is essential. Over decades, I have continuously deepened my vision on sports, health, and quality of life. Cold Steel is the result of this process. I value it most when clients feel so much better that they take new steps in their lives—with heads held high and shoulders straight. The same applies to us as Koudstalers: we learn every day, and our studio is our laboratory.

  • Decades of experience in sports, health, and quality of life
  • Developer of the Cold Steel training philosophy
  • Ongoing learning through practice and experimentation in the studio
MORE ABOUT HIT

Bihter

My goal is to guide people toward a healthier and happier life through exercise, with an objective and realistic approach that supports personal development.

I worked for many years as a physical therapist in Turkey (Istanbul), where I gained experience in clinical pilates and biotechnology research. These experiences showed me the powerful effects exercise can have on the human body. As a spinal health specialist, I now provide my services at Cold Steel, supporting clients as they work toward better health and growth.

Workout Goals:

COUNTERACT AGING: HIT creates maximum muscle mass and stimulates vitality of your whole body. Does not lead to wear, but strengthens caps, attachments, tendons and bones. HIT takes injuries into account and aids rehabilitation.

MORE POWER AND ENERGY: HIT stimulates your muscles and energy systems. Combined with good nutrition and a healthy life style, you will become next level strong and energetic.

LOSE WEIGHT SUSTAINABLY: HIT gets you out of the ‘yo-yo’, you lose weight in a controlled and durable manner. Your fat tissue transforms into muscle and you feel better.

(TOP)SPORT BETTER: HIT supports your sports practice, creates a more balanced muscular system and reduces your sensitivity for injuries. Also ideal in between the competition seasons.
