5 min firechat about the science behind the Reactive Falling Effect
How does Logic Workout outperform 3X weight training, Pilates & calisthenics while eliminating chronic pain?
The science shows the brain is at the center of it all. We created exercises based on the "Reactive Falling Effect" using a fitball that rolls, deforms, and springs simultaneously. This forces the brain to give full attention to movement, essentially hacking the nervous system.

The Reactive Falling Effect
- Deformation: 'The inflated ball’s surface changes shape under load, altering the contact area and friction dynamics.
- Spring Effect: Elastic rebound on the ball from compression creates oscillations that must be controlled.
- Rolling: The ball moves freely in multiple directions, eliminating fixed pivot points.

How it started
Welcome! My name is Paul, and I'm from France. This is how it all started: in 2006, I suffered from a severe snowboarding accident that injured my right leg. After two operations and three years of physiotherapy, my leg was 6cm smaller in circumference. I could barely walk, and doctors told me I would need a cane for the rest of my life. I refused to accept this diagnosis! Instead of training with weights in one-dimensional motions, I used my engineering background in mechanics to create a method to activate the weak muscle fibers, fascia and train the nervous system: the Reactive Falling Effect. Within six months of daily 10-minute exercises, my leg was fully restored in terms of both strength and flexibility. Witnessing these mind-blowing results, I decided to apply the same logic to the entire body, thus creating Logic Workout.
