Mentioned often in advanced asana and pranayama instruction but rarely explained in full, bandhas — energetic "locks" within the body — represent one of the more advanced and genuinely misunderstood elements of classical Hatha Yoga practice.
A bandha involves a specific muscular contraction and engagement at a particular point in the body, traditionally understood to redirect and contain prana (vital energy) that would otherwise dissipate, intensifying its effect within the body rather than allowing it to disperse. Unlike simply tensing a muscle, a properly engaged bandha involves subtle, sustained engagement rather than forceful gripping.
Engaging the muscles of the pelvic floor — similar to, but more subtle and sustained than, a standard Kegel contraction — Mula Bandha is traditionally associated with grounding energy and supporting the base of the spine during both seated practice and more dynamic movement.
Drawing the lower abdomen inward and slightly upward, beneath the rib cage, Uddiyana Bandha is traditionally practiced on an empty stomach and an exhaled breath, often combined with breath retention. This bandha is associated with stimulating digestive fire and supporting the lower back and core during more demanding postures.
Created by drawing the chin gently toward the chest while lengthening through the back of the neck, Jalandhara Bandha is commonly used during pranayama practice involving breath retention, traditionally understood to protect the head and heart from excessive pressure buildup during retained breath.
Independent of the traditional energetic framework, bandhas have genuine biomechanical relevance — Mula Bandha and Uddiyana Bandha closely correspond to deep core and pelvic floor engagement that supports spinal stability during challenging postures, connecting directly to the practical anatomy covered in our spine and asana guide.
The most frequent error is excessive force — gripping and straining rather than the subtle, sustained engagement the practice actually calls for. Another common mistake is holding the breath entirely while attempting Uddiyana Bandha outside of its traditional context (on an exhale, with appropriate breath retention), which can create unnecessary strain rather than the intended benefit.
Given the genuine subtlety required and the potential for strain through incorrect practice, bandhas are best learned with direct, hands-on guidance rather than from written description alone. This advanced technical instruction forms part of the curriculum in our 300-hour advanced program, building on the foundational pranayama work covered at the 200-hour level.
