Supine Figure Four — Full Pull-In: A Complete Guide
Quick Intro
Supine Figure Four — Full Pull-In is a static stretch performed by lying on the back, crossing one ankle over the opposite knee, lifting the bottom foot off the floor and interlacing the fingers behind that thigh to pull both legs firmly toward the chest.
Equipment Needed
No equipment is required for Supine Figure Four — Full Pull-In, though a yoga mat is a common, optional addition for a comfortable lying base.
Why Supine Figure Four — Full Pull-In Matters
Pulling both legs firmly toward the chest with the ankle crossed over the knee drives a deep opening through the buttock (gluteus maximus) and outer hip (gluteus medius) of the crossed leg, while the inner thigh (adductors) opens as the knee travels outward and the front of the hip (hip flexors, iliopsoas) is held fully shortened as the whole shape draws inward.
Flexibility is the main demand, and a very high one, with some endurance work in sustaining a firm two-handed pull.
When to Do It
Supine Figure Four — Full Pull-In works well once the more passive versions of this hold already feel comfortable, typically after running, cycling or any session involving repeated hip rotation.
A current knee issue calls for caution with the crossed leg here, since the deep pull adds more load through that joint than a gentler hold does.
Getting Ready
Lying down and crossing the ankle over the knee without lifting the bottom foot yet previews how the hip feels today before adding the full pull. A few gentle hip circles beforehand loosen the same area this deeper draw asks more of.
Keep the low back flat against the floor as the pull deepens, rather than letting it round or lift, since a flat spine is what keeps the effort concentrated in the hip and out of the lower back.
Step-by-Step Instructions
1. The cross. Lie on the back and cross one ankle over the opposite knee.
2. The lift. Raise the bottom foot off the floor.
3. The clasp. Interlace the fingers behind the bottom thigh, not over the shin.
4. The pull. Firmly draw both legs toward the chest, keeping the crossed ankle flexed.
5. The release. Ease the pull off and lower both feet before switching sides.
How Many, How Often
Supine Figure Four — Full Pull-In is dosed by time held, since the hip opens further the longer the pull is sustained.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to the two-handed pull | Hold for 15 to 20 seconds, pulling gently. |
| Intermediate | The low back stays flat through the pull | Hold for 20 to 30 seconds. |
| Advanced | The hold no longer needs active correction | Hold for 30 seconds, the legs settling noticeably closer to the chest. |
A flat low back matters more here than how close the legs draw toward the chest, since a low back that lifts to force the legs closer trades the hip stretch for one that leans on the spine instead.
Modifications and Variations
Supine Figure Four — Full Pull-In sits at the deepest end of a short progression, with a middle step and an easier step below both.
For an easier version, Supine Figure Four Stretch keeps the bottom foot on the floor or adds only a light pull, offering the same hip release with less demand on the low back.

Common Mistakes to Avoid
Letting the low back lift or round to chase the pull. This shifts effort away from the hip and into the spine instead. Keeping the low back pressed flat, even if it means a shallower pull, keeps this stretch targeting the right area.
Letting the crossed ankle relax out of its flexed position. An unflexed ankle lets the crossed knee bear more of the pull than it should. Keeping that foot actively flexed throughout protects the knee joint.
Yanking the legs in with a sudden, sharp motion. A quick, forceful pull can strain the hip before the tissue has warmed to the stretch. Drawing the legs in gradually, letting the tension build on its own, keeps this whole stretch under control.
After Your Set
Easing the pull off and lowering both feet back to the floor releases the stretch cleanly. Straightening both legs out flat for a few breaths helps the hips settle before switching sides or standing up.
Going Deeper
Progress in this stretch comes from treating a flat, grounded low back as the skill, not from chasing how close the legs draw toward the chest. Muscular strength has no part in this hold, so the limit is set by how much length the outer hip has to offer on a given day, not by how hard the arms pull. A pull that keeps the low back flat for the entire hold, regardless of exact leg position, is the pull that stays in the outer hip.
Someone new to this stretch generally finds a comfortable, gentle pull within the first session, and reaches a full 30-second hold with the legs drawn noticeably closer to the chest somewhere in the two to three week range.
How to Know You’re Improving
- A gentle pull with the low back staying flat against the floor
- A 20-second hold with the crossed ankle staying actively flexed
- A 30-second hold with the legs settling noticeably closer to the chest
- A pull that feels roughly even on both sides
A flat, grounded low back through the whole hold, not raw pull depth, is the marker of progress here.
Muscles Worked
- Gluteus Maximus (the largest glute muscle, taken to its deepest stretch once both legs are pulled firmly to the chest)
- Gluteus Medius (a smaller glute muscle at the side of the hip, lengthened fully by the combined cross and pull)
- Iliopsoas (the deep hip flexor, held completely shortened with both hips drawn in)
- Adductors (the inner thigh muscles, opened on the crossed side as the knee travels outward)
FAQ
Why is this the deepest version of the figure four? Actively drawing both legs toward the torso creates a deeper fold than either resting the shape passively or adding only a light pull, which is why it comes last in the progression.
Is it normal for my low back to want to round during this stretch? It’s a common tendency, especially as the pull deepens, but it’s worth actively resisting. A flat low back is what keeps the stretch working on the hip rather than the spine.
What if I can’t clasp my hands behind my thigh comfortably? Looping a towel or strap behind the thigh bridges the gap. Holding the shin is best avoided, since pulling from there loads the knee.
How is this different from the standard Supine Figure Four Stretch? Both use the same crossed-leg shape, but this version commits fully to the two-handed pull every time, while the standard version treats the pull as optional and often lighter.
