## What is Logic Workout?

RESULTS IN LESS TIME — BACKED BY REAL SCIENCE
Logic Workout uses logic-balls to create the Reactive Falling Effect — a proprietary method grounded in science that activates deep stabilizer muscles and balance reflexes that conventional training completely misses.
Created by an ETH Zurich professor and alumni. Published in scientific research.
10 to 40 minutes of intensive training. Just press start.
The logic-ball's unique combination of rolling, deformation, and elastic rebound creates true multi-axis instability, something BOSU balls, TRX, or free weights simply cannot replicate.
Your entire kinetic chain works as one connected system, the way your body was designed to move.

WHAT USERS ARE SEEING
- Stronger glutes, defined abs, and visible toning in weeks — not months
- Chronic back and joint pain significantly reduced or eliminated
- Athletes gaining strength and injury resilience as a training supplement
- Postpartum mothers returning to peak fitness in 2-3 months
- Rehabilitation patients recovering faster than with conventional physiotherapy

WHO IS IT FOR
Busy Professionals — Superior results in 10-20 minute sessions. Two hours per week outperforms six hours at the gym.
Women — Sculpt your glutes, core, and full body. The instability forces deep muscle activation that isolated exercises can't match.
Athletes & Lifters — Add as a supplement. Users report significant strength gains within 3 months by targeting stabilizer muscles and movement imbalances.
Chronic Pain — Back pain, joint issues, postural problems. The reactive training reactivates your body's natural stabilization system.
Postpartum Recovery — Rebuild your core and pelvic floor safely with progressive programs.
Rehabilitation — Post-surgical recovery, joint injuries, neurological conditions including Parkinson's disease.

THE APP
Just Press Start — no complicated setup
Video Instructions — detailed guidance for every exercise at every level
Progressive Levels — from Entry to Master
Customized Programs — strength, pain relief, glutes & toning, sport-specific
Activity-Specific Warmups — tennis, boxing, skiing, running
Flexible Sessions — 10 to 40 minutes, on your schedule
Performance Tracking — monitor your progress over time

APPLE WATCH — UNLIKE ANY OTHER FITNESS APP
Track what no other app measures. Our Apple Watch integration provides scientific-grade biomechanical analytics in real time:
→ Logic Effort Score (LES) — measures true neurophysiological demand
→ Stability percentage and movement consistency
→ Jerk analysis (movement smoothness)
→ Heart rate tracking
→ 50Hz sensor sampling — research-validated precision
Watch your neuromuscular control improve session by session with metrics that go far beyond calories and heart rate.

THE SCIENCE (FOR THE CURIOUS)
The fitball's ~100ms response time matches the human neuromotor reaction window. Small positional shifts create significant angular displacement, optimally stimulating your motor control system. This reactivates balance reflexes developed in childhood — effectively reopening neuroplasticity windows in adults.

### 5/5 — Great workout / Highly recommended

*2026-05-12*

I was diagnosed with Parkinson’s disease 08/2020. In 07/2025 I started RSB. In 11/2025 I started Logic Workout. Parkinson’s had caused me to lose strength and muscle mass. Between my diet and Logic Workout I am slowly regaining my strength and muscle mass. Don’t let the videos fool you. Paul makes the exercises look easy. They are not. Some of the exercises under the easy tab were brutally hard for me.  But slowly but surely I am working my way up to the medium tab. I can actually perform some of the exercises at the hard level. What’s great is I can workout at home when time permits. Without question this beats pumping iron at a gym.

### 5/5 — Great for beginners and pros

*2025-05-01*

I had a lower back pain for months and these workouts removed the pain in 2 sessions. Insane! I like how you can take it at any level while still feeling you are having a good workout.

### 5/5 — The perfect workout for the road and home

*2024-12-13*

I have been in search of the perfect workout while traveling and at home and logic workout has it all!! I always thought I needed the perfect gym, shoes etc and really you need you own body and two workout balls and this app.  Thank you 🦩

### 5/5 — Easy to use and great workouts

*2024-10-31*

Exercises are challenging but feasible. I'm 1 month in and I love it. Definitively works!

### 5/5 — The ultimate workout

*2024-09-20*

At first I thought these workouts looked easy and it would be no big deal but boy was I shocked to feel so many muscles I have NEVER felt before being pushed to the limit. When doing the squats- It felt as difficult as squatting a bunch of weight at the gym. 

Will be canceling my gym membership after trying this app. 3 minutes a day to see results- does it get much better?? 

Definitely give Logic a shot to whip you into shape.

### 5/5 — Really tough and rewarding workouts!

### 5/5 — Great Work Out!!!

*2023-08-13*

I love this app—Great workout progressions, Intelligently designed, straight forward and easy to follow— the use of the ball makes it so the muscles work a lot, but it’s low stress on the body!!!
Highly recommend
