Modern Yoga Styles and Their Foundation in Hatha Yoga

By Marleen van Erp

Today, when most of us think of Yoga, we picture the physical practice – the asanas – expressed in many different ways: flowing Vinyasa, structured Ashtanga, alignment-focused Iyengar, calm Yin, and so on. Yet technically speaking, these are not different “types of yoga”, but rather different asana styles– different ways of approaching the physical practice within a much larger yogic system.

Beneath this diversity of modern asana styles lies a shared lineage: Hatha Yoga. Traditionally, Hatha Yoga was never meant to be just physical exercise or a collection of poses. It is a complete system that includes asana, pranayama, mudra, bandha, shatkarmas (purification techniques) and meditation. In the classical understanding, Hatha practices are preparatory and supportive methods that cultivate steadiness for the higher limbs of yoga, helping the practitioner move toward deeper states of awareness. Not shaped by trends, but by centuries of transmission and lived practice.

Traditional Hatha Yoga

The word Hatha itself carries deep meaning: “Ha” representing the sun or solar energy, “Tha” representing the moon or lunar energy within our bodies. Together, they symbolise balance – the harmonising of opposites: effort and surrender, strength and softness, activity and stillness. This principle lies at the heart of all authentic yoga practices, and is something tangible we experience every time we practice consciously.

Popular Modern Asana Styles

The asana-based practice we see in studios around the world today primarily draws on this Hatha foundation. The variations encountered in modern yoga styles are expressions of how teachers and lineages have interpreted and applied these core teachings over time across different contexts and student needs.

What differs from style to style is emphasis: pace, sequencing structure, degree of physical intensity, alignment precision, use of props and teacher methodology. What remains constant are the underlying principles of Hatha: breath awareness and the gradual cultivation of steadiness and ease (sthira and sukha) in practice, which allow body and mind to settle into balance and union.

Hatha Yoga

Hatha yoga, often described as the “classical” physical yoga in modern studios, is static, slower-paced, breath-focused, and ideal for building a strong foundation. In Hatha classes, poses are typically held longer, the breath is consciously observed, movement is connected with internal awareness, and transitions are often steady rather than rushed. There is usually space. Space to arrive in a posture. Space to observe the breath. Space to notice where effort is needed and where tension can be released. The aim is not performance, but presence.

Hatha practice prepares the body, regulates the breath, steadies the nervous system, and gently guides attention inward. From this foundation, many other expressions of practice have evolved.

Ashtanga Yoga

Developed in the 20th century by Sri K. Pattabhi Jois, Ashtanga follows a structured, dynamic sequence of postures practised in a specific order. Movement is closely linked to breath, creating rhythm, heat, and focus. Its traditional Mysore-style method encourages disciplined self-practice within a guided setting, cultivating discipline, consistency, and internal concentration.

Vinyasa Yoga

Vinyasa is an umbrella term for practices that link movement to breath in a dynamic, flowing sequence. Unlike Ashtanga’s fixed series, Vinyasa allows for creative sequencing and thematic exploration. The essence of Vinyasa lies in continuity – one posture unfolding into the next, guided by the rhythm of inhalation and exhalation. It can be strong and energising or slow and fluid, depending on the class’s intention.

Iyengar Yoga

Founded by B.K.S. Iyengar, this style focuses on precise alignment and intelligent sequencing, often using props to make yoga accessible and safe for all bodies. Classes may be slower, and postures arefrequently held longer, allowing practitioners to study structure, stability, and subtle adjustments with careful attention.

Yin Yoga

Yin Yoga moves at a very different pace. It’s slow and meditative. Poses are held for longer periods to gently target connective tissue rather than muscular strength, encouraging stillness, surrender, and introspection. Instead of effort, there is softening. Instead of striving, there is observation and release.

Aerial Yoga

Aerial Yoga is a modern variation of traditional asana practice in which a hammock supports the body. It draws inspiration from traditional postures and adapts them using gravity. Because the hammock partially supports body weight, certain poses become more accessible, while the instability introduces a distinct challenge for strength and coordination.

Different expressions of the same foundation

Many other styles have emerged from the Hatha framework, including Bikram/Hot Yoga (set sequences in heated rooms), Restorative Yoga (props and relaxed holds), Anusara (heart-centred alignment), and more. Each carries its own flavour and emphasis, yet all share a common root in Hatha Yoga’s physical and energetic principles.

Hatha Yoga in the Modern World

At its essence, Hatha Yoga – and asana practice more broadly – remains rooted in the same fundamental intention: to prepare the body and steady the breath, guiding the practitioner inward – from the gross, physical level toward subtler layers of experience.

While modern Yoga often emphasises movement and physical expression, the classical purpose of Hatha Yoga remains deeply relevant today. In a fast-paced, externally oriented world, it offers a way to regulate the nervous system, cultivate mental clarity, and reconnect with inner stillness.

For many practitioners, building a strong foundation through classical Hatha Yoga provides stability and orientation – a grounded base from which other styles of practice can be explored with a deeper understanding of the principles of Yoga.

Your Training & Practice at Raj Yoga School

At Raj Yoga School, the rich spectrum of yogic expression is honoured while remaining grounded in tradition. The Multi-Style yoga teacher training courses (YTTC) are rooted in Hatha yoga principles. From this foundation, students explore the dynamism of Vinyasa and the disciplined structure of Ashtanga. This approach allows students not only to experience different asana methodologies but also to explore the broader practices within Hatha Yoga, including pranayama, bandha, mudra, and meditation.
