Hi, I’m Yossi!
My work began with a personal challenge: back pain and anxiety that affected how I showed up. Training on the stability ball changed how I moved, breathed and carried myself.
Over more than two decades, I have developed Performa Ball into a practical coaching method. Today I help leaders and professionals build the physical foundation for clearer communication, steadier presence and greater confidence under pressure.

"When I started The Core Confidence Experience, my posture was so bad I could barely move. I really doubted it would help me! But Yossi's sessions? They were like they were made just for me and have regained my posture and my life."
— Michael Laufer
"... and the best part is, I'm moving without any pain. At almost 50, I feel like I could walk onto any stage with complete confidence!"
— Marc Green - CFO
"Yossi, The Core Confidence Experience was a total game-changer for my balance. Seriously, I could barely even stay on that ball in the beginning! But now? My core feels so much stronger, my posture's way better, and I actually feel like I have a real presence about me."
— Hadene Gratch - CTO
Real presence starts with inner stability.
Core Centered Posture
True presence starts from within. The stability ball activates deep core muscles that support grounded, confident posture.
Integrated Presence Skills
We use physical movement - on the ball - to shift how you feel and show up in real time.
Move with Ease
Low-impact and joint-friendly, the ball helps release tension and build embodied ease you can take into any room.
Stay Centered Under Pressure
This isn’t mindset coaching. It’s nervous system training. The ball gently rewires how your body responds to stress, so you stay steady under pressure.
STAY INFORMED
Improve your posture and confidence, one email at a time.
Simple strategies to build real presence - delivered monthly. No spam, just tools that work.
