Mid-back freedom above, hip freedom below, and the first side-wall work in between.
Trunk endurance, not maximal strength, protects the back — poor extensor endurance predicted first-time back pain.
Side planks and carries train the lateral core that stops the pelvis dropping — the muscles most people never train.
A stiff mid-back sends bending and twisting downstairs to the lumbar spine. Free the mid-back to spare the low back.
Three couplets · two rounds · twelve minutes · a calmer, stronger back
Knees stacked; open the top arm and follow with the eyes, knees together.
Easier smaller · Harder 3-s pause
Low back gently on the floor; lower one arm overhead slowly on the exhale.
Easier shorter reach · Harder both arms
Ankle on the opposite knee; rock the legs gently toward the chest.
Easier smaller · Harder pull the thigh
On all fours; lift the knee out to the side, belly quiet, no lean.
Easier smaller · Harder pulse at the top
Elbow under the shoulder, knees bent; lift the hips to a straight line.
Easier shorter holds · Harder straighten the top leg
Face down; squeeze the glute first, lift the leg a hand-width, low back quiet.
Easier bent knee · Harder 2-s hold
Each couplet: 60 s slow, scored → the reps → 10 s to move on. Done at 12:00.
