A brick under the mid-back turns extension from something you do with your lower back into something you can direct at one segment at a time. This sequence uses it in two ways — as a support to drape over while breathing, and as a fulcrum to move over — and pairs both with rotation, because a mid-back that can extend but not turn is still going to send the load somewhere else.
| Step | Hold | Side | What you should feel |
|---|---|---|---|
| 1. Cat and cow | 70s + 5s | both sides | Six rounds to move the segments before you load them. Note which part of the back moves least — that is where the brick goes. |
| 2. Brick extension, low | 65s + 10s | both sides | Brick under the mid-back, hands supporting the head, elbows up. Start with the brick lengthways for a gentler angle, and breathe into the ribs for the whole hold. |
| 3. Brick extension, crossways | 70s + 5s | both sides | Brick crossways under the same segment for a stronger angle. Stop at the point where the lower back still feels flat on the floor. |
| 4. Sphinx | 65s + 10s | both sides | Forearms down, elbows under the shoulders, front ribs drawing back. This is the same extension without the prop — the contrast tells you how much of it you can now hold yourself. |
| 5. Prone swan | 70s + 5s | both sides | Hands pressing down, chest lifted a hand higher than sphinx. Legs heavy, glutes soft, and no lifting of the chin. |
| 6. Thread the needle | 65s + 10s | left side | Left arm under, shoulder and temple down. Rotation right after extension — this is where you find out whether the new range can actually be used. |
| 7. Seated rotation | 70s + 5s | both sides | Sit tall on the brick, hands crossed on the chest, turn each way four times. Compare the two directions to how they felt at the start of the session. |
| 8. Child's pose with reach | 65s + 10s | both sides | Sit back to the heels, arms forward, and let the back round completely. After ten minutes of extension, the flexion is what makes the change stick. |
The brick is only useful if it is under the segment that is not moving. Roll it up or down the mid-back one vertebra at a time and find the spot where, when you drape over it, the movement happens at the brick rather than at the neck or the lower back. That is the segment to work. Most people find it between the shoulder blades, at the level of the bottom of the shoulder blade tips.
Loaded extension is the direction most likely to hurt if it is done carelessly:
Extension and rotation are the pair that a stiff mid-back loses together. Once you have the extension, the sequence uses it in a rotation — the thread the needle and the seated rotation are there so the new range is available in a movement you actually make. Doing the extension and stopping is the most common way this sequence gets run and the least useful version of it.
A painless crack as the segments open is common and is usually gas releasing from the joint. It is not the goal, and chasing it by dropping harder onto the brick is how people end up sore. If the crack comes with pain, stop and reduce the height of the support.
A rolled towel or a thin cushion is a better starting point for most people. The brick is roughly nine centimetres, which is a lot for a stiff mid-back. Use whatever height lets you breathe slowly in the position; the height is not the achievement.
Daily is fine at low height. If you are working at brick height and it produces a satisfying but strong sensation, four or five times a week is plenty — the tissue needs a day off between strong extension sessions.
The deep glute muscles sit under the big one and rotate the hip. They are also the muscles that most often get blamed for a pain that is actually coming from somewhere else — which is why this sequence spends its first steps on the positions that reliably change how the back of the hip feels, and its last steps on the movement that tells you whether it worked.
Rotation is the movement the mid-back is built for and the one it loses first. A seated sequence can train it all day long because rotation is the one direction you can work without standing up or lying down. This one takes ten minutes and treats rotation as the main event rather than as a step at the end of a stretching routine — two directions, four positions, and a breathing step to finish.
Nothing here is meant to change your range. This sequence is about the thing that actually decides how you sleep: whether the body is still holding the day in its back and hips when you lie down. Every step is slow, every step ends lying or sitting, and the last one is chosen so that getting into bed afterwards is a two-second movement rather than a project.
