Not just a ball workout: The REACTIVE FALLING EFFECT

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.

  • How Olympians boost their performances.

    Olympic athlete @nathaliemoellhausen reduced her training from 10h/week to 3h/week and reached better performance. This enables her to recover faster and train on her fencing skills.

  • 15% Strength Gains in Just 4 Hours

    Weightlifters incorporating just 1 hour of Logic Workout per week reported 15% strength increases within 4 training sessions. David G. added 25 pounds to his squat with minimal lower-body focus, while Scott achieved multiple personal records after only two weeks.

  • Giving racing pilots ligthning reflexes.

    It’s unique because it’s performance training you can take anywhere. The fitball inflates or deflates in seconds, and the app provides full-body workouts.

  • 3x more effective than weight training

Chronic pain relief

eliminated years of back pain in just 2 hours

Where conventional training and even surgery fell short, Logic Workout delivered. A Pilates instructor eliminated years of back pain in just 2 hours. Isabelle released shoulder tension in only 6 minutes. Florian canceled his scheduled L4-L5 surgery after 2.5 months of training, reporting full recovery, while Didier, 65+, overcame multiple open fractures with titanium implants to return to extreme sports and perform 100 push-ups.

Parkinson's, Stroke patients, MS

Even her doctor couldn’t see signs of Parkinson’s anymore.

At 75, Liselotte was living with advanced Parkinson’s—tremors, stiffness, and constant reliance on help. But after just two months of Logic Workout training, everything changed. She now walks freely, cooks for hours, and climbs steep stairs without assistance. Her fine motor skills, sleep, and focus have returned, and she states herself that all symptoms are gone—results far beyond what years of therapy and medication had ever achieved.

In her own recent testimony, she shared: “Today I was at the orthopedist who operated on both my knees. He told me you wouldn’t even notice I have Parkinson’s. I walked steadily, even under stress. The elevator was broken, and I went up multiple stories on foot.”

We are launching a rigorous A–B–A–B clinical study to uncover the mechanisms behind Logic Workout’s rapid, transformative outcomes. Each of the major claims—chronic pain reduction, strength gains, quality of life improvements, general fitness, and reactive postural control—is being linked to outcome measures that are well-validated, reliable, and responsive. The study will combine patient-reported outcomes, standardized functional and physiological tests, and continuous monitoring. We are partnering with scientists from the LLUI research labs to ensure methodological rigor and scientific credibility. Through this collaboration, we aim not only to document what changes occur with Logic Workout, but also how those changes are achieved.

How it started

My name is Paul, and I'm from France. 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! 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.
