Supine Figure Four Stretch: A Complete Guide
Quick Intro
Supine Figure Four Stretch is a static stretch performed by lying on the back, crossing one ankle over the opposite knee to form a figure-four shape, then either holding the position or pulling both legs toward the chest.
Equipment Needed
No equipment is required for Supine Figure Four Stretch, though a yoga mat is a common, optional addition for a comfortable lying base.
Why Supine Figure Four Stretch Matters
Crossing the ankle over the knee while lying on the back lengthens the buttock (gluteus maximus) and the outer hip (gluteus medius) of the crossed leg, while the inner thigh (adductors) opens as the crossed knee falls out to the side and the front of the hip (hip flexors, iliopsoas) stays short as the legs draw toward the chest.
Flexibility is the main demand, and the floor carries the body so the hip can be worked with no balance load.
When to Do It
Supine Figure Four Stretch works well after running, cycling or any session involving repeated hip rotation, when the outer hip and glutes have been under sustained tension, or as a calming addition to an evening stretch routine.
Anyone with a current knee issue should keep the crossed foot flexed and the pull light, since the flexed ankle is what keeps the crossed knee from twisting under load.
Getting Ready
Lying down and crossing the ankle over the knee without pulling yet previews how the outer hip feels today. A few gentle hip circles loosen the same area this deeper hold asks more of.
Keep the crossed foot gently flexed rather than pointed, since a flexed foot protects the knee of the crossed leg by keeping it from bearing weight through the pull.
Step-by-Step Instructions
1. The setup. Lie on the back with both knees bent, feet flat on the floor.
2. The cross. Cross one ankle over the opposite knee, forming a figure-four shape.
3. The choice. Either hold the position with the bottom foot flat, or interlace fingers behind the bottom thigh.
4. The pull. If pulling, gently draw both legs toward the chest.
5. The release. Uncross the ankle and lower both feet to the floor before switching sides.
How Many, How Often
Supine Figure Four Stretch is dosed by time held, since the outer hip releases gradually as the position settles in.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to the figure-four shape | Hold for 15 to 20 seconds, foot flat on the floor. |
| Intermediate | The shape holds steady without added pull | Hold for 20 to 30 seconds. |
| Advanced | The hold no longer needs active correction | Hold for 30 seconds, adding a gentle pull toward the chest. |
A flexed crossed foot matters more here than how close the legs pull to the chest, since a relaxed, flexed foot protects the crossed knee regardless of how deep the overall hold goes.
Modifications and Variations
Supine Figure Four Stretch sits in the middle of a short progression, with an easier step below it and a harder step above.
For an easier version, Supine Figure Four — Foot Flat holds the shape with the bottom foot flat on the floor, skipping the added pull entirely.
For more difficulty, Supine Figure Four — Full Pull-In draws both legs fully toward the chest for a deeper stretch.

Common Mistakes to Avoid
Letting the crossed foot point instead of staying flexed. A pointed foot lets the crossed knee bear more of the pull than it should. Keeping the foot gently flexed throughout protects that joint.
Pulling the legs in before the crossed shape itself feels settled. Adding a strong pull onto an unfamiliar hip position makes both harder to manage. A few sessions just holding the shape, without pulling, builds a comfortable base first.
Lifting the head and shoulders off the floor to reach the pull. Straining upward to grab the thigh adds neck tension the hip stretch gains nothing from. Keeping the head resting on the floor, or using a small pillow, keeps the focus on the hip.
After Your Set
Uncrossing the ankle and lowering both feet to the floor releases the stretch cleanly. A few gentle knee-to-chest hugs settle the hips before switching sides or standing up.
Going Deeper
Progress in this stretch comes from treating a flexed, protected crossed foot as the skill, not from chasing how close the legs pull to the chest. Since muscular strength never enters into this hold, what limits the pull isn’t effort, but how much length the outer hip has to give on a given day. A hold that keeps the crossed foot flexed and the neck relaxed for the entire duration, regardless of exact pull depth, is the hold that works the hip and spares the knee.
Someone new to this stretch generally finds a comfortable, settled figure-four shape within the first session, and reaches a full 30-second hold with a gentle pull added somewhere in the two to three week range.
How to Know You’re Improving
- A comfortable figure-four shape with the crossed foot flexed
- A 20-second hold with the neck and shoulders staying relaxed on the floor
- A 30-second hold with a gentle pull bringing the legs closer to the chest
- A hold that feels roughly even on both sides
A flexed, protected crossed foot through the whole hold, not raw pull depth, is the marker of progress here.
Muscles Worked
- Gluteus Maximus (the largest glute muscle, stretched on the crossed leg with the floor supporting the low back)
- Gluteus Medius (a smaller glute muscle at the side of the hip, stretched as the crossed knee falls open to the side)
- Iliopsoas (the deep hip flexor, held short as both legs draw toward the chest)
- Adductors (the inner thigh muscles, opened on the crossed side by the figure-four shape)
FAQ
Do I need to pull my legs toward my chest for this stretch to count? No. Holding the figure-four shape with the bottom foot flat on the floor is a complete, effective version of this stretch, and it’s exactly what Supine Figure Four — Foot Flat is built around.
Why does this stretch take less balance than a standing hip stretch? Lying flat on the back means the floor supports the entire body, removing almost all of the stability demand that a standing hip stretch would carry.
Is it normal to feel this stretch more in one hip than the other? Yes, uneven hip tightness between sides is common and usually reflects everyday movement habits.
How do I know when I’m ready to try the deeper full pull-in version? Once a full 30-second hold here feels comfortable with a gentle pull, drawing the legs in fully in Supine Figure Four — Full Pull-In is a reasonable next step.
