“Yossi 'The Core Confidence Experience' was an absolute lifesaver for me, especially during and after my pregnancy. It completely got rid of my back pain, helped, my posture so much for an easier birth, and gave me so much more confidence in every day life”
– Sarah Brookfield
I spent years in a body that hurt
... and a mind that doubted everything. Then I found the one tool that changed both. The stability ball.
24 years later, I teach executives, leaders and professionals to find the same shift. Not through mindset alone, but integrating the body with the mind.
Now I'm here to help you do the same.
I am a certified personal trainer with advanced Swiss ball training certification and over two decades of specialist experience at the intersection of posture, nervous system regulation and executive presence. What I developed is a nervous system training method that uses the stability ball to teach the body what grounded, confident stability actually feels like. 700+ clients. 20+ years. The method that works at the root.
Real Impact. Real Confidence.
