Anti-extension: the front of the trunk learns to stop the low back arching — plank, dead bug and Y-raise.

Three seconds down builds control and tissue tolerance with less load than fast reps.
You are about 1–2 cm shorter by evening as discs lose water, and regain it overnight. Movement drives the exchange.
Three couplets · two rounds · twelve minutes · a calmer, stronger back
Back and arms on the wall; slide up only while the low back stays flat.
Easier arms lower · Harder hold at the top
Exhale as the arm and opposite leg lower; the back never arches.
Easier bent knee · Harder straight leg
Knee up, out to the side, back and round — pelvis frozen.
Easier smaller circle · Harder slower
One foot down, other knee hugged; hips level as you lift.
Easier bridge march · Harder 3-s hold
Elbows under shoulders, glutes on, ribs down; hold straight.
Easier knees · Harder feet together
Face down, thumbs up; lift the arms in a Y from the mid-back, neck long.
Easier smaller · Harder 3-s hold
Each couplet: 60 s slow, scored → the reps → 10 s to move on. Done at 12:00.
