If you’ve spent any time in a pranayama or advanced asana class, you’ve probably heard a teacher murmur something like “engage your lock” or “draw the energy up.” More often than not, they’re talking about the four bandhas — one of yoga’s most subtle, and most misunderstood, internal practices.
Bandha is a Sanskrit word that simply means “to lock,” “to tighten,” or “to hold.” In yogic tradition, the four bandhas are specific muscular contractions used to seal off, direct, and conserve the flow of energy within the body. They’re not stretches or poses in the usual sense — they’re internal actions, invisible from the outside, that quietly transform how breath and awareness move through you.
In this guide, we’ll walk through what the four bandhas are, why yogis have practised them for centuries, how to engage each one safely, and who should approach them with extra caution.
What Are Bandhas?
Think of a bandha as an internal valve. By contracting specific muscle groups — many of which sit at the body’s natural sphincters — you temporarily seal off a passage and redirect the energy trying to move through it. Practitioners describe this energy as Prana, the vital life force that governs breathing, circulation, and every physical and mental function in the body.
There are four main bandhas in yoga:
- Mula Bandha – the root lock
- Uddiyana Bandha – the abdominal (or “flying up”) lock
- Jalandhara Bandha – the throat lock
- Maha Bandha – the great lock, combining all three
The first three can be practised individually. The fourth, Maha Bandha, brings them together into one unified action. Together, these locks form a core part of classical Pranayama practice, and they’re also referenced throughout the Shat Kriyas, the traditional cleansing techniques of Hatha Yoga.
Why Do Yogis Practise the Bandhas?
On the surface, it might seem strange that a practice built around “opening” the body also asks you to close and lock parts of it. But the logic is simple: without containment, energy disperses. Bandhas create the internal pressure needed to direct prana toward the areas of the body — and the mind — that need it most.
Classical texts describe Jalandhara Bandha as sealing the top of the energetic channel running along the spine, while Mula Bandha seals the base, preventing prana from leaking downward and out of the body. When both are engaged together, practitioners often describe a build-up of internal heat, almost like friction being generated between two points, which is further intensified when Uddiyana Bandha is added.
Beyond the energetic explanation, there’s a very practical physiological side to this too. Engaging the bandhas briefly restricts blood flow to certain areas. When the lock releases, blood rushes back in, which many teachers say supports circulation, mobilises stagnant energy, and gives internal organs a gentle, rhythmic “flush.” Modern research on breath control and intra-abdominal pressure lends some support to this idea, showing that controlled engagement of the abdominal and pelvic floor muscles can influence posture, spinal stability, and even the nervous system’s relaxation response.
Benefits of Practising the Four Bandhas
Here’s a quick overview of what regular, mindful bandha practice is traditionally said to offer:
| Bandha | Physical Benefit | Energetic Benefit |
|---|---|---|
| Mula Bandha | Tones pelvic floor, stabilises lower spine | Grounds energy, prevents downward leakage of prana |
| Uddiyana Bandha | Massages abdominal organs, stimulates digestion | Draws energy upward with force |
| Jalandhara Bandha | Regulates thyroid and metabolism, eases neck tension | Seals energy at the throat, calms the mind |
| Maha Bandha | Full-body integration and control | Unifies all energy channels simultaneously |
Beyond the individual benefits, practitioners often report:
- Sharper focus and single-pointed concentration
- A steadier, more controlled breath
- Improved core strength and postural stability
- A calmer nervous system and reduced stress response
- Better regulation of digestive and hormonal function
It’s worth noting that bandhas are typically introduced during Pranayama and breath-retention practices before they’re ever brought into movement. Once the sensation is familiar, many teachers cue a lighter version of the locks during Inversions and arm balances, where core engagement and breath control genuinely aid stability and lightness.
How to Practise Each of the Four Bandhas
A quick note before you begin: these are subtle actions. If you find yourself gripping, straining, or holding your breath until you feel dizzy, you’re doing too much. Bandhas should feel like a gentle internal lift — not a clench.
1. Mula Bandha (Root Lock)
Mula Bandha is usually the first lock beginners learn, and it forms the foundation for the other three.
How to find it:
- Sit comfortably with a tall spine.
- Exhale, then gently draw the muscles of the pelvic floor upward and inward — the same sensation as holding back both urine and a bowel movement.
- Hold this light lift while breathing normally, then release.
A simple trick many teachers use: focus your gaze softly on the tip of your nose. Most people feel a subtle Mula Bandha activate automatically. It also switches on naturally during everyday movements like climbing stairs or balancing on one leg.
Caution: Keep the contraction gentle. Over-squeezing tires the muscles rather than training them, and it’s generally advised to skip this lock during the first few days of menstruation.
2. Uddiyana Bandha (Abdominal Lock)
Uddiyana means “to fly upward,” referring to the way the diaphragm and abdominal organs lift and draw back toward the spine.
How to practise it:
- Stand with your feet shoulder-width apart, or sit comfortably.
- Exhale completely, emptying the lungs as much as possible.
- Without inhaling, perform a “false inhale” — the physical action of breathing in without actually drawing air into the lungs. This creates a vacuum that pulls the belly up and back, toward the spine.
- Hold for a few comfortable seconds, then release the abdomen before inhaling naturally.
Caution: Always practise Uddiyana Bandha on a completely empty stomach, ideally first thing in the morning. It should only ever be done during external breath retention (holding the breath out), never while holding a breath in.
3. Jalandhara Bandha (Throat Lock)
This lock seals the energy flow through the neck and throat and is rarely practised alone — it’s usually combined with breath retention in pranayama.
How to practise it:
- Sit tall in a comfortable cross-legged position, hands resting on the knees.
- Inhale, then lower your chin toward your chest while lengthening the back of the neck.
- Gently press the chin toward the sternum, creating a soft “double chin” and a light stretch at the base of the skull.
- Hold briefly, then lift the head and release before exhaling.
This lock is said to compress the arteries and nerves of the neck, which some practitioners link to a calming effect on the nervous system and support for healthy thyroid function.
4. Maha Bandha (The Great Lock)
Once you’re comfortable with the three individual locks, Maha Bandha brings them together in sequence:
- Engage Mula Bandha first.
- Exhale fully and add Jalandhara Bandha.
- Fold slightly forward and draw in Uddiyana Bandha.
- Hold all three together for a few comfortable seconds.
- Release in reverse order — Uddiyana first, then Jalandhara, then Mula — before taking a natural breath.
Because Maha Bandha asks the body to coordinate three separate actions at once, it’s considered an advanced technique. It’s best explored only after each individual lock feels steady and familiar, ideally with guidance from an experienced teacher.
Who Should Be Cautious With Bandha Practice?
Bandhas are powerful, and “powerful” always comes with a few guardrails. It’s generally recommended to avoid or modify bandha practice if you:
- Are pregnant
- Have high or low blood pressure that isn’t well managed
- Have a hernia, ulcer, or other abdominal condition
- Have a heart condition
- Are in the first few days of your menstrual cycle (particularly for Mula and Uddiyana Bandha)
- Are prone to anxiety or panic attacks
If any of these apply to you, speak with a qualified yoga teacher or your doctor before adding bandhas to your practice.
A Few Practical Tips for Beginners
- Start seated, not moving. Learn each bandha in stillness before you try to apply it in asana or Inversions.
- Practise on an empty stomach. This is especially important for Uddiyana Bandha and Maha Bandha.
- Less is more. A light, sustainable engagement is more effective — and safer — than a hard, forceful squeeze.
- Pair them with breath awareness. Bandhas are traditionally taught alongside Pranayama, not as a stand-alone gym exercise.
- Be patient. It’s common to activate the wrong muscles at first (like the glutes instead of the pelvic floor). Refinement comes with time.
Conclusion
The four bandhas — Mula, Uddiyana, Jalandhara, and Maha — are some of the most nuanced tools in the yogic toolkit. They ask for patience rather than power, and subtlety rather than strain. Practised consistently and mindfully, they can deepen your breath, steady your mind, and bring a new layer of awareness to both your Pranayama and your asana practice.
If you’re new to this territory, start slow, start seated, and consider learning directly from an experienced teacher who can guide your first Mula Bandha experience. Curious to go further?

Frequently Asked Questions
The four bandhas are Mula Bandha (root lock), Uddiyana Bandha (abdominal lock), Jalandhara Bandha (throat lock), and Maha Bandha (the great lock, which combines all three). Each one is a specific muscular contraction used to direct and conserve prana in the body.
Yes, but it’s best to start with Mula Bandha alone and under the guidance of a qualified teacher. Uddiyana and Maha Bandha are more advanced and should only be introduced once the root lock feels stable and familiar.
Always on an empty stomach, ideally in the morning or at least three to four hours after a meal. This is especially important for Uddiyana Bandha, which involves drawing the abdominal organs upward.
Not exactly. While bandhas do involve muscular engagement similar to core activation, they are traditionally understood as subtle energetic locks rather than purely physical exercises. The muscular action is the doorway; the intention behind it is what makes it a bandha.
It’s generally advised to avoid Uddiyana and Maha Bandha during pregnancy, and to skip Mula Bandha during the first few days of your period. Always check with a knowledgeable teacher or healthcare provider if you’re unsure.
