The figure 4 stretch is the most effective and most versatile piriformis stretch available. Named for the shape the legs make when the ankle of one leg is crossed over the knee of the other, it places the hip in the specific combination of flexion and external rotation that produces a direct, controlled stretch on the piriformis and the other deep hip external rotators.
Unlike many stretches that have one definitive version, the figure 4 stretch has at least eight meaningful variations that serve different purposes, different fitness levels, different environments, and different clinical presentations. Knowing which variation to use, when, and how to progress between them is the difference between a stretch that produces lasting flexibility improvement and one that provides temporary relief without long-term change.
This guide covers every meaningful variation of the figure 4 piriformis stretch with complete instructions, precise hold times, and clear progression pathways.
Why the Figure 4 Stretch Is the Most Effective Piriformis Stretch
The piriformis muscle runs from the sacrum (base of the spine) to the top of the femur and functions as a hip external rotator when the hip is in extension and as a hip abductor when the hip is flexed beyond 60 degrees. To stretch it effectively, the hip must be placed in flexion combined with adduction and internal rotation, which pulls the muscle into its lengthened position.
The figure 4 position achieves this precisely:
Hip flexion: The crossed leg is brought toward the chest, placing the hip in flexion.
Hip external rotation: The ankle crossing over the knee places the hip in external rotation, which is the shortened position of the piriformis. Paradoxically, this is how the stretch works: by bringing the hip into external rotation with flexion, the piriformis is pulled into a lengthened and stretched position because the muscle must elongate to allow this combined movement.
Adduction component: Drawing the knees toward the chest adds an adduction component that further lengthens the piriformis.
The result is a stretch that targets the piriformis in its functional range more precisely than any other common stretch.
Why it is safer than pigeon pose: As discussed in the stretch piriformis and piriformis syndrome exercises to avoid articles on this site, the pigeon pose compresses the piriformis between the greater trochanter and the floor in a position that can worsen piriformis syndrome. The supine figure 4 stretches the piriformis without this compressive mechanism, making it the preferred stretch during active piriformis syndrome.
The Complete Figure 4 Stretch Variations
Variation 1: Supine Figure 4 (Basic Version)
The foundational variation and the recommended starting point for all levels.
Best for: General piriformis tightness, piriformis syndrome (safest option), post-training recovery, beginners.
Difficulty: Beginner
Equipment: Floor or mat
Instructions:
Step 1: Lie flat on your back with both knees bent and feet flat on the floor, hip-width apart.
Step 2: Cross the right ankle over the left knee. The right ankle should sit just above the left kneecap, with the right foot flexed (toes pointing toward the ceiling) to protect the right knee joint.
Step 3: Observe whether you feel a stretch already. For people with significant tightness, the figure 4 position alone with both feet on the floor produces a stretch.
Step 4: If no stretch is felt, gently press the right knee away from the body with the right hand. This increases the external rotation of the right hip and deepens the stretch.
Step 5: For a deeper stretch, lift the left foot off the floor. Clasp both hands behind the left thigh and draw the left knee toward the chest. The right leg comes with it, deepening the stretch.
Step 6: Hold the position, focusing on slow, relaxed breathing. With each exhale, consciously relax the right hip muscles and allow the stretch to deepen slightly.
Step 7: Hold for the prescribed duration, release slowly, and repeat on the other side.
Where to feel it: Deep in the right outer buttock. The stretch should feel like a deep aching pull in the muscle, not a sharp or burning sensation.
Common errors and fixes:
Error: Foot not flexed on the crossed leg.
Fix: Flex the ankle (toes toward ceiling) before crossing. This protects the knee joint by locking the ankle and preventing rotation stress at the knee.
Error: Knee of the crossed leg pushing forward rather than falling outward.
Fix: Gently press the crossed knee away from the body with the hand to increase the external rotation of the hip.
Error: Lower back lifting off the floor during the stretch.
Fix: Reduce the range of the knee-to-chest pull until the lower back can remain flat on the floor.
Error: Holding the breath.
Fix: Focus on slow, deep breathing. The exhale phase is the most effective moment to allow the muscle to relax further into the stretch.
Hold times:
- Light tightness: 30 seconds per side
- Moderate tightness: 45 to 60 seconds per side
- Piriformis syndrome management: 60 to 90 seconds per side
- Flexibility development: 60 to 90 seconds per side
Frequency: 2 to 3 times per day for tightness relief, once daily for maintenance.
Variation 2: Supine Figure 4 With Strap or Towel
For people who cannot reach behind the thigh comfortably or who have shoulder or arm limitations.
Instructions:
Step 1: Set up in the standard figure 4 position.
Step 2: Loop a resistance band, yoga strap, or towel around the left thigh.
Step 3: Hold both ends of the strap and use it to draw the left knee toward the chest.
Step 4: The strap removes the shoulder flexibility and arm strength demands of the standard variation.
Step 5: Hold for 60 to 90 seconds per side.
When to use this variation: When shoulder tightness, rotator cuff issues, or arm fatigue during the stretch reduce the ability to maintain the position with the hands.
Variation 3: Supine Figure 4 With Foot Against Wall
A passive variation that requires no active effort to maintain the position.
Best for: Evening stretching and relaxation, pre-sleep routine, people with fatigue or weakness that limits active holding.
Instructions:
Step 1: Sit close to a wall, then lie on the back and place both feet flat on the wall with knees bent.
Step 2: Cross the right ankle over the left knee in the figure 4 position.
Step 3: Allow gravity to create the stretch without any active effort. The wall supports the legs in the stretched position.
Step 4: Adjust the distance from the wall to control the intensity:
- Closer to the wall: less stretch (legs more vertical)
- Further from the wall: deeper stretch (legs more horizontal)
Step 5: Hold for 90 to 120 seconds per side. Longer holds are appropriate because no active effort is required to maintain the position.
Why this is particularly effective: The complete absence of muscular effort required to maintain the position allows the piriformis to relax more fully than in any active version of the stretch. The relaxation that occurs over a 90 to 120-second passive hold in this position produces greater flexibility change per session than shorter active holds.
Variation 4: Supine Figure 4 With Gentle Overpressure
An advanced version for athletes seeking maximum stretch intensity in the supine position.
Instructions:
Step 1: Set up in the standard figure 4 position with the left knee drawn toward the chest.
Step 2: Once holding the position, use the left hand to apply gentle additional pressure to the right knee, pressing it further away from the body (increasing external rotation).
Step 3: The right hand draws the left thigh closer to the chest simultaneously.
Step 4: This dual pressure increases both the external rotation and the hip flexion, producing a more intense stretch on the piriformis.
Step 5: Apply the overpressure gently and progressively, never forcefully. The additional stretch should produce a deeper pull in the buttock without pain.
Hold times: 45 to 60 seconds per side.
Caution: Do not use this variation if it produces knee discomfort on the crossed leg or if symptoms include sciatic referral.
Variation 5: Seated Figure 4
The most practical variation for office workers and daytime stretching.
Best for: Office breaks, desk stretching, people who cannot easily access a floor.
Difficulty: Beginner
Equipment: Chair
Instructions:
Step 1: Sit upright at the edge of a chair with both feet flat on the floor.
Step 2: Cross the right ankle over the left knee, creating the figure 4 shape.
Step 3: Sit as tall as possible, lengthening the spine before adding any forward hinge.
Step 4: Hinge forward slowly from the hips, maintaining a long, neutral spine. Think of bringing the sternum toward the crossed shin rather than the nose toward the knee.
Step 5: Continue hinging until a clear stretch is felt in the right buttock.
Step 6: Hold for the prescribed duration, breathing slowly and allowing the hip to relax further with each exhale.
Step 7: Return to upright slowly and switch sides.
The critical cue for this variation: The forward hinge comes from the hips, not from rounding the lower back. A rounded-back hinge reduces the piriformis stretch and increases the load on the lumbar discs. Maintain the natural lumbar curve throughout the hinge.
Hold times: 30 to 60 seconds per side
Desk stretching protocol: Perform 30 seconds per side every 60 to 90 minutes during prolonged sitting. This brief, frequent approach prevents the cumulative tightening that prolonged sitting produces in the piriformis.
Variation 6: Standing Figure 4
The most accessible variation requiring no mat or chair.
Best for: Pre-training warm-up, gym stretching, any situation where a mat is unavailable.
Difficulty: Intermediate
Equipment: Wall or sturdy surface for balance support (initially)
Instructions:
Step 1: Stand facing a wall or holding a chair back for balance.
Step 2: Shift the weight onto the left foot.
Step 3: Cross the right ankle over the left knee.
Step 4: Bend the standing left knee and push the hips backward, as if sitting into a low chair.
Step 5: Simultaneously hinge the trunk slightly forward from the hips to deepen the stretch.
Step 6: Lower until a clear stretch is felt deep in the right buttock.
Step 7: Hold for the prescribed duration.
Step 8: Return to standing and switch sides.
For the complete range of standing figure 4 variations, progressions, and balance development, see the piriformis stretch standing article on this site, which covers the standing variation in full detail.
Hold times:
- Pre-training warm-up: 20 to 30 seconds per side
- Post-training: 30 to 45 seconds per side
Variation 7: Figure 4 in Chair Squat Position (Deep Version)
A deeper version of the standing figure 4 for athletes with good balance and hip flexibility.
Instructions:
Step 1: Stand without support.
Step 2: Cross the right ankle over the left knee.
Step 3: Lower into a deep squat position on the standing leg (as if sitting into a low chair that does not exist).
Step 4: Extend both arms forward for balance.
Step 5: Hold the lowest comfortable position with a clear piriformis stretch.
Step 6: Hold for 30 to 45 seconds per side.
Why this is more demanding than the standard standing version: The deeper squat position places the standing hip in greater flexion, which changes the line of pull of the piriformis and often produces a deeper stretch than the quarter-squat standing version. It also requires significantly greater balance and quad strength to maintain.
Progression to this variation: Master the standard standing figure 4 (Variation 6) at a half-squat depth before attempting this variation.
Variation 8: Figure 4 on Elevated Surface
Uses an elevated surface to stretch the piriformis without deep single-leg squatting.
Best for: Athletes who cannot achieve a sufficient stretch from the standard standing variation, people with knee conditions limiting the squat.
Equipment: Chair seat, bench, or surface at hip height
Instructions:
Step 1: Stand facing a surface at approximately hip height.
Step 2: Place the right shin horizontally on the surface (knee bent, foot over the edge).
Step 3: Keep the right knee pointing outward and the right hip in external rotation.
Step 4: Stand upright and feel the initial stretch.
Step 5: For a deeper stretch, hinge forward from the hips while maintaining a flat back.
Step 6: Hold for 30 to 45 seconds per side.
Surface height progression:
- Below hip height: less intense
- At hip height: moderate intensity
- Above hip height: most intense (yoga barre level)
Variation 9: Dynamic Figure 4 (Warm-Up Version)
A movement-based variation appropriate immediately before training.
Best for: Pre-training preparation, warm-up activation.
Instructions:
Step 1: Stand on one leg (supported by a wall initially).
Step 2: Cross the opposite ankle over the standing knee.
Step 3: Slowly lower the hips over 3 seconds.
Step 4: Hold for 3 seconds at the bottom.
Step 5: Return to standing over 2 seconds.
Step 6: Repeat 8 to 10 times per side.
Tempo: 3 seconds down, 3 seconds hold, 2 seconds up
Why dynamic before training: Research suggests prolonged static stretching (45 seconds or more) immediately before high-intensity training may reduce power output. The dynamic variation provides the mobility and piriformis activation benefit of the figure 4 stretch without the extended static hold.

Frequently Asked Questions
Why does the figure 4 stretch hurt my knee?
Knee discomfort during the figure 4 stretch is common and usually indicates that the hip external rotation range is insufficient for the crossed position to be comfortable at the ankle-over-knee placement. Solutions: ensure the ankle (not just the foot) is resting over the knee, not the lower part of the thigh; flex the ankle (toes toward ceiling) to lock the ankle joint; reduce the depth of the stretch; and focus on building hip flexibility gradually. If knee discomfort persists, the supine figure 4 with the foot on the floor (minimal external rotation) is a gentler starting point.
How do I know if I am stretching the right muscle?
The stretch should be felt as a deep aching pull in the outer buttock of the crossed leg (right buttock when the right ankle is crossed over the left knee). If the sensation is primarily at the front of the hip, the hip flexors are being loaded rather than the piriformis. If the sensation is at the inner thigh, the adductors are being stretched. If the sensation is behind the knee, the hamstring is the primary focus rather than the piriformis. Adjusting the degree of external rotation of the crossed hip (pressing the knee away from the body) helps direct the stretch toward the outer buttock.
Should I feel the figure 4 stretch in both hips or just the crossed one?
The primary stretch should be in the outer buttock of the crossed leg (the leg forming the top of the figure 4). If a stretch is also felt in the inner thigh of the straight leg, the adductors are being loaded on that side, which is a secondary benefit. If no stretch is felt in the crossed leg’s buttock, the hip external rotation and flexion combination is not sufficient: deepen the knee-to-chest pull or press the crossed knee further away from the body.
Can I do the figure 4 stretch every day?
Yes. The figure 4 stretch in its supine and seated variations is gentle enough to perform daily without recovery concerns. Daily practice produces faster and more lasting flexibility improvements than less frequent stretching. The wall-supported supine version is particularly suitable for daily practice because it requires no active effort and can be held for 90 to 120 seconds in a fully relaxed position.
Is the figure 4 stretch the same as the pigeon pose?
Both stretch the piriformis and external hip rotators but through different mechanisms. The figure 4 stretch places the hip in external rotation and flexion without the compressive load of the ground-based pigeon pose position. Pigeon pose additionally compresses the piriformis between the greater trochanter and the floor. For most athletes, the figure 4 is safer during active piriformis syndrome, while pigeon pose can produce a deeper stretch for those without compressive symptoms.
