How many reps of Segmental Spinal CARs should you do when you are new to the exercise?

Do 3 to 5 slow, controlled roll-down-and-up cycles, resetting your posture between reps rather than chaining them quickly. Progress by moving even slower through whichever segment feels stiffest, not by adding more cycles.

How do you make Segmental Spinal CARs easier or harder?

For an easier version, do a smaller partial roll through just the upper or lower back before linking the whole spine together. To add challenge, slow the pace down further, add a longer pause at the bottom, or do it standing instead of seated once seated control is solid.

What are Segmental Spinal CARs good for?

They rebuild fine, segment-by-segment control of spinal flexion, which bridges general mobility work and heavier hinging or carrying, useful for lifters and anyone with a stiff, block-moving back. They are a poor fit for acute low back pain, since deliberately flexing through a painful spine is not something this drill is designed to guide you through safely.

Intermediate

Segmental Spinal CARs

Most people flex and extend the spine in a few big chunks and lose the ability to move each segment on its own. Segmental spinal CARs rebuild that fine control by rolling the spine down and back up one vertebra at a time, from the neck through the pelvis. It trains active control of spinal range and is a superb link between mobility work and heavy hinging or loaded carries.

How to do it

1
Sit tall on the floor or a bench with knees bent and hands resting lightly on your shins.
2
Begin at the top by tucking the chin, then peel the spine backward one segment at a time.
3
Continue the smooth articulation down through the mid-back and finally the low back.
4
Reverse the sequence, stacking the vertebrae from the pelvis upward until you sit tall again.
5
Keep the motion slow and continuous so each segment gets its own moment to move.
6
Coordinate your breath, exhaling into flexion and inhaling as you restack.
7
Perform several controlled cycles, resetting your posture between reps.

Tips

Resist the urge to move in one rigid block; the whole point is segment-by-segment control.
Use light hand contact on the shins only for feedback, not to pull yourself around.
Slow down through any stiff zone rather than rushing to the next segment.

Variations

Common mistakes

The chin tuck at the start gets skipped, so the roll begins from the mid-back instead of sequencing down from the neck the way the drill is designed to.
Breath gets reversed, with an inhale into the roll-down instead of an exhale, which tends to brace the trunk right when it needs to stay soft and mobile.
Some people restack from the head down instead of the pelvis up on the way back to sitting tall, reversing the sequence the reps are meant to build.
The knees pull in tighter or splay wider partway through the roll, using leg tension to help move the spine instead of leaving the legs out of it.
The whole roll finishes in two or three seconds instead of one continuous slow pass, so most segments barely get their own moment before the rep is over.
