Ankle On The Knee
The ankle on the knee stretch has you seated or lying down, crossing one ankle over the opposite knee, then gently pressing that knee down or folding your torso forward until you feel a stretch deep in your glute. It targets the glutes, particularly the deeper muscles that rotate the hip, and it's a common stretch for anyone who sits for long stretches or trains lower-body movements regularly.
Why it works
Crossing your ankle over the opposite knee opens up your hip into a rotated position that lengthens the glute muscles on the crossed side, especially the deeper ones responsible for external hip rotation. Adding gentle pressure on the knee, or folding your torso forward, increases that stretch further by closing the angle at your hip. Because these muscles sit underneath the larger glutes and don't get stretched directly by most everyday movement, this position is one of the more efficient ways to reach them.
Set up
- Sit in a chair, or lie on your back on a mat, whichever position you prefer.
- Cross one ankle over the opposite knee, letting that knee fall out to the side.
- Keep your spine long rather than immediately collapsing forward.
How to do it
- Gently press down on the crossed knee with your hand, or begin folding your torso forward if seated.
- Continue until you feel a clear stretch deep in the glute of the crossed leg.
- Hold the position, breathing steadily, without bouncing.
- Ease off gradually rather than releasing suddenly.
- Switch legs and repeat for the same duration.
- Adjust the pressure or fold depth to control the intensity of the stretch.
Form cues
- Ankle rests on the knee, not the shin.
- Press or fold slowly, no bouncing.
- Feel it deep in the glute, not the knee.
- Spine stays long, don't just collapse forward.
Breathing: Breathe slowly and evenly throughout the hold; a long exhale as you press or fold often lets you settle a touch deeper.
Common mistakes
Pressing hard on the knee right away instead of easing in gradually.
Fix: Start with light pressure and increase it slowly as the muscle relaxes into the stretch.
Rounding the entire spine forward instead of hinging from the hips.
Fix: Keep your chest lifted and fold from your hips if you're adding a forward bend, rather than curling your whole back.
Feeling pain in the knee joint rather than a stretch in the glute.
Fix: Reduce the pressure or the angle immediately; the sensation should be muscular, never in the knee itself.
Bouncing to try to deepen the stretch faster.
Fix: Hold the position steady; a controlled hold lengthens the muscle more reliably than repeated bouncing.
How to program it
- Hold for 20 to 30 seconds per side, 2 or 3 times, most days if glute flexibility is a priority.
- It fits well after lower-body training, when the muscles are warm, or as a break during long periods of sitting.
- Progress gradually over weeks as range improves; there's no need to force new range every session.
Safety notes
- If you have sensitive knees, keep the crossed leg relaxed rather than pressing hard against the joint.
- The sensation should be a clear but comfortable pull deep in the glute, never sharp pain.

Frequently asked questions
How long should I hold the ankle on the knee stretch?
Twenty to thirty seconds per side, repeated 2 or 3 times, is a solid routine. Consistency over days and weeks matters more than pushing hard in any single session.
Why do I feel this stretch more on one side than the other?
Side-to-side flexibility differences are common and usually not a concern. Spend a little extra time on the tighter side rather than forcing both to match immediately.
Can this stretch help with sciatica-like discomfort?
Tightness in the deep glute muscles is sometimes associated with that kind of discomfort for some people, which is one reason this stretch is commonly recommended. It isn't a treatment for nerve-related pain, so see a professional if that discomfort persists or radiates down the leg.
Seated vs lying down: which version of this stretch is better?
The seated version lets you add a forward fold for extra depth, while the lying version removes gravity's pull on your spine and can feel gentler on the lower back. Both stretch the same muscles; pick whichever feels more comfortable for you.
