Mula Bandha: How to Find It, and What It Is Not
Written and reviewed by The Kriya Yogi · Updated 19 September 2026
Mula bandha is the most talked-about and least clearly taught of the three locks. In a modern class it is usually a one-line cue — "engage mula bandha" — with no explanation of where, how much, or for how long. The classical description is more specific about purpose and much less specific about anatomy than most students expect.
The short answers
- Mula means root; the lock is a contraction of the pelvic floor region, held during breath retention in the classical account.
- The texts do not pin it to one modern anatomical structure, and lineages differ between the perineum, the anal sphincter and the cervix.
- Practically: a light lift upward and inward, without clenching the buttocks, gripping the belly or holding the breath.
- Squeezing the anus hard is ashwini mudra, a related but different practice.
- Release is part of the practice. Constant all-day engagement can worsen pelvic-floor symptoms rather than help them.
- If you have pelvic pain, prolapse symptoms, or are pregnant or post-partum, see a pelvic health physiotherapist before practising.
What the texts say, and how much they leave open
The Hatha Yoga Pradipika lists Mulabandha among its ten mudras in the third chapter, describes a contraction at the root with the heel pressed against the perineum, and frames the result in its own terms — the downward-moving apana is turned upward and joined with prana. The Gheranda Samhita gives a comparable account in its own mudra chapter.
What the texts do not give is an anatomy lesson. There is no mention of the pubococcygeus, no distinction between the superficial and deep layers of the pelvic floor, no discussion of the differences between male and female pelvic anatomy. Teachers have filled that gap in different ways, which is why you will hear mula bandha located at the perineum in one room, at the anal sphincter in the next, and at the cervix in a third. The honest position is that this variation is real and old, and that the practical instruction — a gentle lift at the base of the pelvis — is compatible with all of them.
Finding it without clenching
The most common error is force. A hard squeeze recruits the buttocks, the inner thighs and the abdomen, stiffens the breath, and teaches exactly the pattern you do not want. Mula bandha, done well, is subtle enough that a person sitting beside you cannot see it.
A workable approach:
- Sit comfortably, hips above knees, spine easy. A firm meditation cushion makes the pelvis do less work to stay upright.
- Exhale normally. On the pause at the end of the exhalation, draw the area between the pubic bone and the tailbone gently upward and slightly inward.
- Hold for two or three seconds without holding your breath. The breath should be able to continue if you let it.
- Release completely. Feel the difference between contracted and released — that contrast is the skill.
- Six to ten repetitions is plenty for an early session.
If you cannot feel anything, that is common and not a failure. Lying on your back with knees bent often makes the sensation clearer than sitting does.
Mula bandha, ashwini mudra and kegels
Three practices get conflated constantly:
- Mula bandha — a subtle lift at the base of the pelvis, classically held during retention and aimed at redirecting prana.
- Ashwini mudra — a repeated, distinct contraction and release of the anal sphincter, named separately in the hatha literature.
- Pelvic-floor exercises (kegels) — a twentieth-century clinical protocol for pelvic-floor strength, with its own dosage and its own evidence base for specific continence and prolapse indications.
They overlap physically. They do not share aims, dosage or evidence, and research on pelvic-floor training tells you nothing about the traditional claims made for mula bandha.
The over-engagement problem
Some modern teaching encourages holding mula bandha continuously — through a whole practice, or as a general postural habit. For a subset of people this is actively unhelpful. A pelvic floor that is already overactive responds badly to more tone; symptoms can include pain, urgency, difficulty releasing and discomfort during intimacy. Pelvic health physiotherapists see this pattern regularly.
If you have any pelvic symptoms, treat lifting as something you learn alongside releasing, and get assessed before building a daily practice around it.
Where this fits
Read the three bandhas for the overall picture, maha bandha for the combination, and who should not practise bandhas before adding retention.
In practice
Set the seat first
Hips above knees on a cushion or folded blanket, spine upright without bracing. A collapsed pelvis makes the lock impossible to feel.
Exhale, then lift
At the end of a normal exhalation, draw the base of the pelvis gently up and in. Aim for subtle, not strong.
Keep the breath free
You should be able to breathe through the contraction. If the breath stops or the jaw tightens, you are using too much effort.
Release completely
Let go fully between repetitions and notice the contrast. Learning to release is half the practice.
Keep the dose small
Six to ten light repetitions, a few times a week, is enough to build the sensitivity. More is not better here.
Add retention only with a teacher
The classical practice holds the lock during kumbhaka. That combination belongs in person, after months of steady breathing.
Cautions worth reading
- Bandhas are muscular and breath practices, not treatments. Stop if you feel dizzy, breathless, pressured in the head or eyes, or any pelvic pain, and speak to a doctor, midwife or pelvic health physiotherapist before practising if you are pregnant, recently post-partum, recovering from abdominal or pelvic surgery, or managing high blood pressure, glaucoma, hernia, epilepsy or heart disease.
- Do not hold mula bandha continuously through the day; a permanently gripped pelvic floor is a problem, not an achievement.
- Pelvic pain, prolapse symptoms, urinary urgency, pregnancy or recent birth all warrant a pelvic health physiotherapist before you practise.
- Hard clenching that recruits the buttocks and abdomen is not the practice; less effort is usually more accurate.
- Do not use mula bandha as a treatment for incontinence or sexual difficulties — those need proper assessment.
Where the evidence stands
No trial has tested mula bandha as such. The pelvic-floor training literature is substantial but studies a different, clinically specified intervention, and its results cannot be transferred to a traditional lock practised for energetic reasons. The reasonable claim is mechanical: a voluntary pelvic-floor contraction happens, and learning to contract and fully release that region deliberately is a real motor skill. Anything beyond that — prana, apana, awakening — is tradition, and should be read as such.
