Hi, I’m Yossi!
I grew up with hearing loss, wore hearing aids and was bullied through school. I know what it feels like to lose confidence in how you show up.
Discovering the stability ball changed how I moved, breathed and carried myself. Over 24+ years, I developed that practice into the Performa Ball methodology. Today I help leaders train the body that delivers their message — and meet pressure with greater steadiness and presence.

Presence Lab

“Before training with Yossi, I felt less confident and less comfortable speaking up and sharing my thoughts. … that physical balance translated into increased confidence.”

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.
