Pilates Reformer Long Spine
What Is the Pilates Reformer Long Spine?
Pilates Reformer Long Spine is a compound exercise that primarily targets the core and also engages the hamstrings, glutes and back extensors. It is an advanced-level movement performed lying face up on the reformer with both feet in the long straps, and the resistance comes from the carriage springs pulling through those straps. From a supine start the legs press long, the pelvis and spine peel off the carriage into a supported shoulder stand, and the spine then rolls back down one vertebra at a time.
It belongs late in the reformer repertoire, after the supine leg-strap work, and it is normally taught once a client can already bridge and articulate the spine with control. Studios also call it Long Spine Massage, because the roll-down is meant to feel like each vertebra is pressed into the carriage in turn. It is an inversion, with the hips finishing above the head, so it is trained as a controlled skill for a few slow repetitions rather than as a conditioning exercise.
The abdominals do the controlling work, flexing the spine to peel it off the carriage and then paying it out segment by segment on the way down, while the hamstrings and glutes press into the straps to raise the pelvis and keep it high. The back extensors and the adductors hold the lifted line together, and the arms press lightly into the carriage for support. Long Spine is also taught on the mat and on the Cadillac, and a study of healthy women found the mat version produced more oblique activity through the lifting phase and more rectus abdominis activity on the way down than the reformer version, which fits the way the straps and springs carry part of the load here. The classical version opens the legs to shoulder width at the top and closes them at the bottom, reversing that order on alternate sets, and taking spring tension away removes support from under the lifted pelvis rather than making the exercise easier.
It suits experienced Pilates clients who already have the hamstring length to hold the legs straight overhead and a neck that tolerates weight on the upper back and shoulders. If the bridge itself is the limit, build up with Pilates Reformer Lying Pelvic Lift, which keeps the feet on the footbar and asks only for a steady pelvis. Think of reaching the legs long into the straps rather than throwing the hips up, because the lift should come from the press of the legs and the sequence of the spine.

Instructions
- Set two heavy springs, lay the headrest flat, and check the straps are long enough to reach your feet with the carriage closed.
- Lie face up on the carriage with your head on the headrest and the tops of your shoulders against the shoulder blocks.
- Put both feet in the long straps, feet parallel and together, and rest your arms long by your sides with the palms down.
- Bend your knees in toward your chest so the carriage sits closed and the straps are just taut.
- Press your legs long to about 45 degrees, keeping your pelvis heavy on the carriage and your ribs down.
- Press down into the straps and draw your legs toward vertical, then peel your pelvis and spine off the carriage one vertebra at a time.
- Stop once your weight rests on your upper back and the tops of your shoulders, with your body in one long line from your shoulders to your feet and your legs reaching up over your hips.
- Keep space behind your neck, keep your head still on the headrest, and hold the press into the straps for one breath.
- Roll your spine back down one vertebra at a time, keeping your hips as high as the straps allow so your pelvis and your feet arrive at the bottom together.
- Return your legs to the start position at about 45 degrees and repeat, then bend your knees and take your feet out of the straps to finish.
Common Mistakes
Rolling onto the neck
Lifting so far that the weight shifts off the upper back and onto the neck, closing the space behind it.
Hinging instead of articulating
Lifting and lowering the back as one rigid block rather than moving through the spine one vertebra at a time.
Losing strap tension
Letting the legs drift so the straps go slack, which removes the support under the lifted pelvis.
Dropping the hips early
Letting the pelvis fall to the carriage at the start of the roll-down, so the feet arrive long after the hips.
Muscling up with the arms
Driving hard through the hands to throw the pelvis up instead of pressing the legs into the straps.
Turning the head
Looking around while inverted, which twists the neck under the weight of the lifted body.
Injuries
Pilates Reformer Long Spine is a medium risk exercise when performed with proper technique. It is an inversion performed on a moving carriage, so most of the risk sits in two places: the neck, which must never take the weight that belongs on the upper back and the tops of the shoulders, and the lower back, which gets loaded when the spine hinges as one block instead of articulating. The straps add a third, since losing tension while the pelvis is high lets the load drop suddenly.
Lay the headrest flat, keep the space behind your neck, and stop the lift before the weight would roll past the tops of your shoulders. Keep your head still and facing the ceiling for as long as you are inverted. Use enough spring tension for the straps to support the lifted pelvis, check before you start that the straps are long enough to reach your feet with the carriage closed, and keep your arms pressing lightly into the carriage rather than shoving yourself up with your hands. Roll down slowly enough that the hips stay high until the last moment, which is what keeps the lower back out of it.
If the lift or the roll-down is beyond you, build the bridge first with Pilates Reformer Lying Pelvic Lift, or stay in this setup and lift only as far as the base of the shoulder blades until the articulation is smooth. Tight hamstrings usually show up as bent knees or a lost strap connection, so work on hamstring length before chasing height. To progress, slow the roll-down, add the classical opening and closing of the legs, or pause partway down and hold the line.
Stop the set and come down if you feel pain or pressure in your neck, pinching in your lower back, a hamstring cramp, or dizziness or pressure in your head while inverted. Pilates teaching keeps inverted work away from pregnancy and from anyone with a neck or lower back injury, osteoporosis, uncontrolled high blood pressure or an eye condition such as glaucoma, so get it cleared with a clinician before it goes in a program.

Frequently Asked Questions
- Q: How is this different from Short Spine?
Long Spine keeps the legs straight and rolls the body down in one long line, while Short Spine bends the knees in toward the shoulder blocks and rolls down through that folded shape. Both are feet-in-straps inversions, and Short Spine is usually learned first.
- Q: How many springs should I use?
Two heavy springs is the common setting, with a third sometimes added on a longer reformer so the straps still carry tension at the top. Check the straps reach your feet with the carriage closed, because straps that are too short cut the lift short.
- Q: Do the legs stay together the whole time?
In the version shown here they stay together from start to finish. The classical Long Spine Massage opens the legs to shoulder width at the top and closes them at the bottom, then reverses that order on the next set.
- Q: What should I work on if this is still too much?
Get the bridge and the spring control first with Pilates Reformer Lying Pelvic Lift, and spend time on supine leg work in the straps until pressing into them feels automatic. Lifting only to the base of the shoulder blades is a useful halfway step.
- Q: Why does my neck feel pressure at the top?
Almost always the lift has gone too far, so weight has rolled off the upper back and onto the neck. Come down slightly, keep the headrest flat and keep space behind the neck. If the pressure stays, stop and have any diagnosed neck condition cleared before you invert again.
- Q: How many reps should I do?
Three slow repetitions is a normal set, and the quality of the articulation matters far more than the count. End the set once the spine starts moving as a block or the hips drop early on the way down.
