Short Spine and Long Spine are advanced reformer exercises in which you lie on your back with your feet in the straps, lift the legs and pelvis overhead, then roll the spine back down one vertebra at a time. In Short Spine the knees bend before you roll down, keeping the movement compact. In Long Spine the legs stay straight, so the spine articulates against a much longer lever. Both are as much about control on the way down as the lift on the way up.
Written by the Elemental Movement Lab and reviewed by Samantha Giam, certified classical Pilates instructor. Updated 1 October 2026. This guide brings together our own teaching with three leading Pilates references, listed at the end.
Before you start: setup and safety
- On an Elemental Reformer TerraFold™, your head rests directly on the flat carriage, which has no headrest to lower. Your shoulders rest against the shoulder rests, so check their bolts are tight before you begin.
- Place your feet in the foot straps and check every carabiner gate is fully closed. Your legs will hang from these straps overhead.
- Start on medium springs. Lighter springs demand more pelvic control, and heavier springs give more support.
- Inverted spinal flexion is not for everyone. If you have neck, spinal or bone-health concerns, including osteoporosis, or are pregnant, seek individual guidance before attempting either exercise.
Short Spine vs Long Spine at a glance
| Short Spine | Long Spine | |
|---|---|---|
| Also called | Short Spine Massage | Long Spine Massage |
| Legs overhead | Straight, then the knees bend towards the shoulders | Straight throughout, often opening slightly |
| Roll down with | Knees bent, heels close to the seat | Legs long, lowering as the spine unrolls |
| Main emphasis | Lifting the hips high and articulating the spine | Articulation against a long lever |
| Level | Advanced | Advanced, usually harder |
How Short Spine moves, step by step
- Lie down, feet in the straps, heels together and toes slightly apart, legs straight at about 45 degrees. Arms long by your sides, palms pressing into the carriage.
- Lift the straight legs overhead as the pelvis peels off the carriage, until the hips are over the shoulders and the carriage has closed.
- Keeping the hips high and the straps taut, bend the knees towards the shoulders.
- Roll the spine down one vertebra at a time, the feet staying over your face.
- With the tailbone down, draw the heels towards the seat, then press the legs back out to the start.
Long Spine follows the same lift, but the legs stay straight and lower towards the carriage as the spine unrolls.
The anatomy: what is working
| Phase | Muscles | Their job |
|---|---|---|
| The lift | Abdominals, hip flexors (iliopsoas, rectus femoris) | Curl the pelvis up and over. The abdominals lead, so the hip flexors do not take over. |
| Overhead | Hamstrings and glutes pressing into the straps | Keep tension on the straps so the pelvis stays lifted. |
| The roll down | Rectus abdominis, transversus abdominis, obliques | Lower the spine segment by segment, working as they lengthen. |
| The return | Hip extensors: glutes and hamstrings | Press the legs back out to the start against the springs. |
| Throughout | Gluteus medius, deep abdominals, pelvic floor, triceps and latissimus dorsi | Keep the pelvis level. The arms pressing into the carriage add stability. |
The key moments you should really feel
- The peel off. As the legs lift, you feel the low abdominals curl the pelvis up. It should feel like a reach from the seat into the straps, not a swing.
- Hips over shoulders. At the top, the weight sits across the upper back and shoulder blades, with space under your neck. You feel the whole back of the body long.
- Bending the knees (Short Spine). This is the moment that separates good from great. The hips want to drop as the knees bend. You feel the glutes and abdominals working hard to keep the pelvis lifted.
- The roll down. You feel each part of the spine touch the carriage in turn, like a string of pearls being laid down. This is the massage in the name.
- The return to start. You feel the back of the legs press out and the springs open with control, not a crash.
How people get it wrong
| Mistake | What it looks like | The fix |
|---|---|---|
| Swinging the legs over | Momentum throws the hips up | Slow down and lead with the abdominals. Reach into the straps as you lift. |
| Weight on the neck | Going too far over, the neck under pressure | Stop when the weight reaches the shoulder blades. Never roll onto the neck. |
| Hips dropping as the knees bend | The pelvis sinks before the roll down begins | Keep lifting the hips as the knees bend. Shorten the range if needed. |
| Losing strap tension | The straps go slack and the carriage jolts | Keep a constant press from the legs into the straps. |
| Hinging instead of rolling | The spine comes down in one stiff piece | Lower one vertebra at a time. Slower is better. |
| The carriage crashing home | The springs snap closed at the end | Reduce the range, slow the return or adjust the springs until you can control it. |
| Hip flexors taking over | A gripping feeling at the front of the hips | Draw the abdominals in first and think of lengthening the legs away from you. |
| Holding the breath | Tension in the face and neck | Keep a steady breath. If you cannot breathe, reduce the range. |
Variations: a progression ladder
| Level | Variation | What it builds |
|---|---|---|
| 1 | Bridge and Shoulder Bridge on the mat or reformer | Spinal articulation and weight on the shoulders, not the neck |
| 2 | Feet in straps: frogs, leg circles and openings | Strap control and a stable pelvis |
| 3 | Short Spine, small lift, heavier springs | The pattern with support |
| 4 | Short Spine, full range | The complete exercise |
| 5 | Short Spine on lighter springs | More pelvic stability |
| 6 | Long Spine | Articulation against the long lever |
| 7 | Long Spine reversed, starting with the legs low | Control in the opposite direction |
How to breathe
Schools differ. Classical teaching often uses the inhale to pause at the top and the exhale to roll down, while some contemporary schools keep an even, continuous breath. This is the pattern we teach.
| Phase | Breath |
|---|---|
| Lift the legs and pelvis overhead | Exhale |
| Pause at the top, and bend the knees in Short Spine | Inhale, breathing into the back ribs |
| Roll the spine down | Exhale, one long breath out |
| Return the legs to the start | Inhale |
Breathe wide into the back and sides of the ribs, especially when inverted. Never hold your breath.
Can you practise them at home?
Experienced practitioners can repeat exercises they have been taught in person, provided the setup suits their reformer. Check the straps, carabiners and shoulder rests before you start. For foundations, see What Is Reformer Pilates? and our Shoulder Bridge guide. For other advanced work, see Long Stretch Series and Arabesque.
FAQs
Is Short Spine easier than Long Spine?
Usually yes, but they are distinct exercises rather than two levels of one. Learn each on its own terms.
Why does my neck feel strained?
The weight is travelling too far towards the neck. Lift less high, keep the weight across the shoulder blades and check setup with your instructor.
Why does my carriage crash at the end?
The return is uncontrolled. Shorten the range, slow down, or adjust the springs until you can close them smoothly.
