Posture That Works in Real Life
B4 helps you find why your body keeps feeling tight, stiff, or uneven. Your Diagnostic turns six simple videos into a clear training direction, so you can move with less tension, build posture that lasts, and stop guessing what to do next.
The Tight Area Is Not Always the Starting Point
After hours at a desk, your neck and shoulders feel tight. Your breathing feels shallow when you try to relax. Your walking feels stiff and uneven. Each symptom is influenced by how the rest of your body moves.
The source is not always where you feel it. B4 analyzes six movements to identify which areas are restricted and which areas are doing extra work. Your report gives you a clear training outline for more efficient movement and posture you can maintain over time.

Send Six Videos and Get Specific Next Steps
More than 30 minutes of focused human analysis goes into every Diagnostic before the report is written.
- 01Answer the questionnaire
Tell B4 what feels tight, what limits you, what you have tried, and what you want to improve.
- 02Record six movements
Short guides show you exactly what to record with your phone.
- 03A real coach will review every video
A B4 coach examines all six recordings in detail, assessing your posture, breathing mechanics, joint mobility, balance, and movement control.
- 04Receive a clear annotated movement report
For each movement, B4 marks the positions where an issue appears so you can see each finding clearly. Every finding is explained in one or two plain-English sentences covering what is happening and why, without dense biomechanics jargon or medical terminology. The report ends with clear next steps showing which areas to relax first, which areas to train, and what order to follow.
