Ardha Hanumanasana: A Complete Guide to Half Hanumanasana
Also called Ardha Hanumanasana
Quick Intro
Ardha Hanumanasana (Half Hanumanasana in English) is a yoga exercise performed kneeling on the back leg with the front leg extended straight forward, heel down, folding the torso forward over the front leg with the hands framing it on the floor or on blocks.
Equipment Needed
No equipment is needed for Ardha Hanumanasana. A yoga mat is optional, and blocks under the hands are a common addition while the hamstring’s range is still developing.
Why Ardha Hanumanasana Matters
Both hamstrings of the front leg (biceps femoris and semitendinosus) lengthen as the torso folds forward, while the front of the hip (hip flexors, iliopsoas) on the kneeling back leg folds as the torso tips forward. The muscles along the spine (erector spinae) support the forward hinge, keeping the fold coming from the hips.
Flexibility is the main demand, centered on the hamstrings of the front leg.
When to Do It
Ardha Hanumanasana works well early in a hip-opening sequence, isolating the front-leg hamstring stretch before Hanumanasana asks for the back leg’s hip flexor to reach the floor as well.
Anyone with a current hamstring strain should keep the fold shallow or skip this pose entirely, since forward-folding pressure directly loads the exact tissue that’s injured.
Getting Ready
A few rounds of gentle leg swings and a low lunge warm the hamstring and hip flexor this pose targets. Kneeling in the setup position without folding forward yet previews the leg placement before the stretch is added.
Keep the front leg’s hip square to the floor and the foot flexed before folding, since the stretch is meant to come from a long spine hinging at the hip, not from rounding the back to reach lower.
Step-by-Step Instructions
1. The setup. Kneel with the front leg’s shin forward and the back leg’s shin resting on the floor.
2. The extend. Straighten the front leg, heel down and foot flexed.
3. The square. Level the hips so both face directly forward.
4. The fold. Hinge at the hips and fold the torso over the front leg, hands framing it on the floor or blocks.
5. The rise. Press through the hands to lift the torso back upright before switching sides.
How Many, How Often
Ardha Hanumanasana is dosed by breath count, since a steady breath keeps the hips square while the hamstring settles into the fold.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to the isolated hamstring fold | Hold for 3 to 5 breaths per side, using blocks under the hands and folding only partway. |
| Intermediate | The hips stay square through the fold | Hold for 6 to 8 breaths per side, lowering the hands closer to the floor. |
| Advanced | The fold settles without strain | Hold for 10 or more breaths per side, or move toward Hanumanasana for a harder challenge. |
Keeping the hips squared forward matters more here than how deep the torso folds, since a rotated hip trades the isolated hamstring stretch for a shallower, twisted version of the pose.
Modifications and Variations
Ardha Hanumanasana sits at the easier end of its progression, with a harder step above it.
For more difficulty, Hanumanasana extends the back leg fully into a floor split instead of keeping the back knee bent and grounded, adding the back hip flexor’s full range on top of the front hamstring stretch.

Common Mistakes to Avoid
Rounding the back to reach further instead of hinging from the hips. This shifts the stretch away from the hamstring toward the lower back. Keeping the spine long as the torso tips forward from the hip crease targets the stretch correctly.
Letting the front hip rotate open rather than staying square. A rotated hip reduces the direct hamstring line the pose is built around. Leveling both hip points forward, even at a shallower fold, keeps the stretch on the hamstring.
Locking the front knee too forcefully. An aggressively locked knee can strain the joint under a deep fold. A soft, active straightness in the knee protects it while the hamstring still lengthens fully.
After Your Set
Sitting back onto the heels and gently rounding into a resting fold over the front leg releases the hamstring after the hold. A breath or two here settles the leg before switching to the second side.
Going Deeper
This pose is usually trained by prioritizing a squared front hip over fold depth, letting the torso lower naturally as the hamstring lengthens over repeated sessions. The most common way it stalls isn’t hamstring tightness alone, but a front hip that quietly rotates open to fake a deeper-looking fold, which trades away the isolated stretch this pose is built to deliver. Keeping that hip square every single session, regardless of how far the torso folds, is what drives progress here.
Someone new to this pose generally holds a steady 5-breath fold on blocks within the first couple of weeks, and reaches a settled hands-on-floor version somewhere in the four to six week range.
How to Know You’re Improving
- A supported fold on blocks with the hips staying square
- The hands lowering closer to the floor without the hip rotating
- A full hands-on-floor fold held for 6 or more breaths
- Readiness to extend the back leg fully into Hanumanasana
The front hip staying square through the entire fold, not how close the hands get to the floor, is the marker of progress here.
Muscles Worked
- Biceps Femoris (the outer hamstring at the back of the thigh, stretched on the extended front leg)
- Semitendinosus (the inner hamstring at the back of the thigh, lengthened as the torso folds over the straight leg)
- Erector Spinae (the muscles running along the length of the spine, lengthening over the front leg as the chest lowers)
- Iliopsoas (the hip flexor group at the front of the hip, folded on the kneeling back leg)
FAQ
Is this pose meant to replace the full split version, or lead into it? It leads into it. Ardha Hanumanasana isolates the front-leg hamstring stretch that the full split builds on, making it the natural preparation step.
Why do I feel this more in my hip than my hamstring? The front of the kneeling hip is folded in this shape and can feel pinched if the hips drift back behind the knee. Stacking the hips over the back knee usually moves the sensation back to the hamstring.
Is it okay to keep the back knee on a folded blanket? Yes, a folded blanket under the back knee is a common addition for comfort and changes nothing about the stretch itself.
How long before I can attempt the full split version? It varies by individual hamstring and hip-flexor length, but a settled hands-on-floor hold here for several weeks is a reasonable signal that the full split is worth attempting.
