Duration chose this first direction. The location survey names where it hurts; it does not swap a third silent file. Chair 90/90 is the sitting / flexion slot. Prone press-up is the extension slot.
Now testing: Prone press-up
Protocol: about 10 repetitions, then reassess. This is not a 10-minute hold. Stop the same session if distal symptoms spread. Jessica is on-camera talent, not the brand. No McKenzie Method or Mulligan claims.
Distal worse, new CES items, or pain 10 → seek care. Not “try the other video.” Same and not worse may try the other direction once. After both with no change, stop. WalkBack 5×30 is after recovery.
Written side-glide (not a third film): /third-direction/
