Yoga science is a spiritual discipline that aims to guide human consciousness towards liberation and to realize its true nature. Health, well-being, and joy ensue as a byproduct of the Yogic journey. However, in modern times, people have confined the meaning of Yoga only to optimal physical & mental health. It is important to understand the meaning of Yoga Anatomy in its truest sense before we delve deeper into exploring the benefits of Yoga for physical health.

Yoga science provides a systematic approach to understanding and optimizing human health and well-being at a holistic level. Another important point to consider here is that health is not limited to just physical health. True well-being and health are possible only when there is positive growth in all aspects of life:

1. Physical
2. Intellectual
3. Mental
4. Emotional
5. Moral
6. Spiritual

Hence, Yoga is a science and art of holistic health and well-being. And when there is an integrated growth of the entire personality on all the above aspects, can a human being be called to be living a wholesome, healthy, and integrated life.

For this study, we will explore in detail how our body moves and functions during Yoga practice. This will require a deeper understanding of human anatomy for us to learn how different poses affect the body. We will also learn how yoga anatomy can help modify the poses according to the practitioner’s needs.

Yoga anatomy involves understanding the various organ systems viz. the skeletal system (bones), muscular system (muscles), cardiovascular system (heart and blood vessels), digestive system, excretory system, endocrine system, lymphatic system, nervous system (brain and nerves) and the interconnected workings of joints, ligaments and tendons. An understanding of Yoga anatomy and physiology is important for a practitioner to bring more awareness of the impact of each asana in one’s practice. Understanding of Anatomy and physiology also helps in deepening awareness and connection with one’s body and mind.

How does understanding Yoga Anatomy and Physiology Enhance the Yoga Practice?

Understanding anatomy and physiology is essential for practitioners to perform Asanas in a structured and scientific manner. This knowledge allows individuals to execute movements accurately, reducing the risk of injuries. Additionally, it enhances overall yoga practice and leads to optimal results. Therefore, studying Yoga Anatomy is crucial in a 200-Hour Yoga Teacher Training program.

It is important for a practitioner to learn Yoga anatomy and physiology for the following reasons:

Curate Safe Sequences & Injury Prevention:

The Yoga practitioners can prevent injuries by understanding the principles of yoga anatomy behind different yoga poses. Practitioners can perform the yoga poses according to the right anatomy and hence gain more benefit. Such practitioners with a knowledge of the complete anatomy of the human body can make proper muscle engagement as well as alignment. Due to this, they can perform the poses correctly and safely while minimizing the risk of strains and injuries.

A teacher well-versed in Anatomy and physiology will be able to identify the anatomical structure of each muscle group and joint. This, in turn, helps the teachers to curate sequences which minimize strain and maximize benefit to the target area.

Optimized Performance with better explanation of benefits to students – Yoga Anatomy

Yoga anatomy helps practitioners enhance their performance. Such practitioners have better knowledge of which muscles to engage and how to distribute body weight to achieve strength, balance, and flexibility in practice.

A teacher proficient in Anatomy and physiology will be able to describe why a particular asana benefits a specific group of muscles, organs, or systems. Hence, such understanding creates value for students and improves their connection with practice.

Personalize Practice according to body type

Each human body is unique. Yoga anatomy helps practitioners modify various poses according to their body type, flexibility, physical limitations, or levels of strength. With the right understanding of principles of yoga anatomy, practitioners can curate a personalized approach according to their body type to enhance the effectiveness of the Yoga practice.

Hence, an understanding of anatomy and physiology is critical in yoga to create a safe, injury-free practice. Yoga anatomy during the Yoga Teacher Training in Rishikesh also helps in effective teaching and mindful alignment.

Now let us explore how understanding of anatomy and physiology during the Yoga Teacher Training helps in the practice of specific postures and supporting major organ systems.

Now let us understand how understanding of anatomy and physiology guides the practice of physical postures for a safe and effective practice.

1.   The Musculoskeletal System and Yoga

The musculoskeletal system consists of bones, muscles, and connective tissues like ligaments and tendons. Yoga anatomy helps in asanas for strengthening and stretching muscles. These asanas help to enhance muscle movement, flexibility, strength, and balance.

Important Muscle Groups in Yoga:

• Core Muscles: Core muscles include the abdominals, obliques, and lower back muscles. Core muscles are responsible for providing support and balance to the spine.

 Asanas that actively engage the core are as below:

1. Plank Pose (Phalakasana)
2. Boat Pose (Navasana) 
3. Side Plank Pose (Vasisthasana)
4. Crow Pose (Bakasana)

These postures aim to engage different areas of the core. These asanas strengthen the core while providing stability to the spine.

• Lower Body Muscles: Many asanas activate the lower body muscles like the glutes, quadriceps, hamstrings, and calves. Asanas that engage the lower body muscles help in increasing flexibility and balance.

1.  Warrior II (Virabhadrasana II)
2. Downward Dog (Adho Mukha Svanasana)
3. Bridge Pose ( Setu banda Asana)
4. Triangle Pose (Trikona Asana)
5. Chair Pose (Utakata Asana)

These asanas strengthen the legs, open the hips, and thereby contribute to good posture. Strong leg muscles provide a protective shield to the knee during asanas and daily life movements.

• Upper Body Muscles: The arms, shoulders, and upper back constitute the upper muscular part.

These muscles can be strengthened by poses such as:

1. Downward-Facing Dog (Adho Mukha Svanasana)
2. Chaturanga Dandasana (Four-Limbed Staff Pose)
3. Plank (Phalakasana)
4. Side Plank
5. Dolphin Pose

It is extremely important to build strength in these muscles so that they support the shoulders and there is less strain on the shoulder joints.

Effect of Anatomy-Informed Yoga on the Muscular System

1.  Increasing flexibility and range of motion

In stretching asanas, muscles are lengthened, which releases tension in them. Postures such as Seated Forward bending (Paschimottanasana) and Camel Pose (Ushtrasana) specifically engage muscles that are stiff, like hamstrings and hip flexors. This releases tension in those muscles and hence, gradually, the range of motion increases. Consequently, the practitioner experiences greater flexibility in movement, which in turn reduces stiffness. Over time, the practitioner will experience more freedom in movement during asanas and off the mat as well. Hence, Yoga Anatomy is taught comprehensively in detail in the 200-Hour Yoga Teacher Training in Rishikesh.

2. Increases muscle strength and motor function

Asanas requiring holding, bearing weight, and balancing help to strengthen the muscles, which increases the body’s stamina.

3. Balance and coordination

Asanas help in improving balance, movement control, and coordination.

4. Improved muscle tone

In asanas, body weight acts as the resistance, which helps in defining and toning muscles.

5. Improved blood circulation

Yoga and pranayama increase blood flow to the muscles, which helps the muscles in growth, faster recovery, and healing.     

6. Relieves pain and inflammatory muscle conditions      

Yoga reduces pain, inflammation, and also helps in certain conditions myositis.

The Skeletal System and Yoga Anatomy

The skeletal system provides structure to the body. It is a framework of the body providing support, protection, and facilitating movement. The Skeletal System consists of bones, joints, connective tissues like cartilage, and ligaments.

Asanas for bone health:

1. Extended Triangle Pose (Trikonasana)
2. Tree Pose (Vrikshasana)
3. Half Fish Pose (Ardha Matsyendrasana)

Effect of Anatomy-Informed Yoga on the skeletal system

• Bone Strength and Density – Yoga postures, especially the ones involving weight bearing, strengthen bones and add to mineral density in the bone.

• Joint Health and Flexibility – Yoga improves the circulation of synovial fluid,d which helps in reducing pain, stiffness and improving joint lubrication.

• Posture and Balance – Postures like Tree pose help in improving balance and coordination, which reduce the chance of fall and misbalance.

• Stress reduction and bone health –Yoga helps in stress reduction, which indirectly supports bone health.

• Delay aging -Regular yoga practice prevents stiffness so that one can maintain joint mobility even in old age. The asanas are carefully curated to mobilize each joint gently and safely. For example, Cat-Cow Pose (Marjaryasana-Bitilasana) improves flexibility in the spine, eases stress & suppression, and provides support to overall back health

3. The Cardiovascular System and Yoga:

The cardiovascular system is made up of the heart, blood, and the blood vessels, viz arteries, veins, and capillaries.

Effect of Anatomy informed Yoga practice on cardiovascular health.

Yoga Anatomy greatly helps the cardiovascular system by:

• Promoting blood circulation
• Strengthening the heart muscle
• Improving lung capacity
• Activating the parasympathetic nervous system response. 
• Improving cardiac output. Also, some asanas work towards increasing heart rate, which over a long period helps in increasing cardiac output.

 Enhancing Blood Circulation

Obesity, heart conditions, venous insufficiency, hormonal disturbances, stress, and anxiety can lead to poor blood circulation. Yoga poses that involve inversion, where the heart is elevated above the head, help enhance circulation by facilitating the return of blood to the heart. Without this, blood can pool in the lower limbs, causing swelling, pain, and limited mobility. Effective asanas include Shoulder Stand (Sarvangasana), Legs Elevated Against the Wall (Viparita Karani), Head Stand (Sirshaasana), and Leg Raises. Improved circulation ensures that oxygen reaches all organs, reducing strain on the heart. Additionally, inverted poses help clear obstructions in Prana, allowing it to flow freely, promoting lightness, mental clarity, and a deeper connection with oneself. Thus, these asanas play a vital role in supporting cardiovascular health through enhanced blood circulation.

Activating the parasympathetic nervous system response

The function of the heart and the Autonomic Nervous System is interconnected. During moments of stress and anxiety, the heart rate is elevated, which puts a strain on the heart muscle. Hence, Asanas that activate the relaxation response help in reducing the burden on the heart. Also, such asanas help in the reduction of cortisol in blood and increase of feel-good hormones, which create a sense of inner safety in the body & mind. Pranayama, Yogic Nidra, Mudra, Nada Yoga help in diffusing the hyper-arousal state & calming the nervous system, which then promotes cardio-vascular health and reduces the risk of stress-related disorders like coronary artery disease, angina, hyper-tension, palpitations, etc. The activities below promote cardiovascular health by reducing stress.

• Yogic Nidra
• Nadaanusandhan
• Ayurveda messages and Shirodhara
• Pranayama techniques like Alternate Nostril Breathing (Nadi Shodhana), Sheetali, Sheetkari, Bhramari, and Belly Breathing
• Mudra Healing

Improving lung capacity

Pranayama techniques like Diaphragmatic Breathing, Bhastrika, Ujjayi (Ocean Breath), and Kapalabhati (Skull Shining Breath) improve air flow, expand lung capacity, enhance oxygen intake, reduce respiration rate per minute, and improve overall respiratory health. Yoga trains the lungs and diaphragm & makes breathing function more efficient. This adds to overall endurance and capacity. At the subtle level, these asanas focused on increasing lung capacity, increasing emotional resilience, and the ability to stay balanced in the complexities of life.

4. The Nervous System and Yoga

Regular practice of yoga helps in creating new neural pathways in the brain, which changes the stress response. Also, asanas and pranayama help in the activation of the parasympathetic nervous system, which is responsible for relaxation. The sympathetic nervous system controls the “fight or flight” response, while the parasympathetic nervous system is responsible for the “rest and digest” state. At the level of the subtle body, these are known as Ida (Moon /feminine energy/ relaxation) and Pingla (Sun/ Masculine energy/activity).

Effect of anatomy-informed Yoga on the Nervous System

·         Calming & Regulating the Nervous System

Restorative asanas focus on activating the parasympathetic nervous system, thereby promoting relaxation and reducing stress.

Child’s Pose (Balasana) 

 Savasana (Corpse Pose) 

·         Reducing Anxiety and Depression

Research has shown that regular yoga practice eases the symptoms of anxiety and depression by the secretion of healing neurotransmitters like serotonin, oxytocin, and GABA (gamma-aminobutyric acid). Asanas and other yogic activities which provide a sense of grounding, centering, & stability promote a sense of safety in the body-mind. This eases stress & anxiety and helps the body return to homeostasis.

·         Improving focus and Clarity

Mind and breath are interconnected. Yoga helps in nervous system health by integrating movement (asanas), breath (pranayama), and mind (mindfulness).

Concentration-building activities like Trataka (Gazing at the tip of a candle) train the mind to focus on one point for a long period, thereby building concentration. Mindfulness-based asanas, pranayama, and other yogic techniques help in bringing one’s consciousness to the present moment. Yoga Anatomy is an important part of the 200-Hour Yoga Teacher Training in Rishikesh.

5. The digestive system and Yoga

The root of all healing lies in the Gut. Also, as per Yoga philosophy, the source of our pranic energy lies in the gut. The digestive system is responsible for digestion, assimilation, and absorption. Yoga can profoundly optimize this process of breaking down and absorption. Asanas and pranayama stimulate digestion, relieve symptoms of acidity, bloating, and bowel-related issues. During the Yoga Teacher Training in Rishikesh, anatomy-informed yoga practice is an important part of the curriculum.

Effect of anatomy-informed Yoga on the digestive system

• Stimulate digestion
• Relieve symptoms of acidity, constipation & bloating and bowel-related issues.
• Enhance the brain-gut connection
• Improve absorption of nutrients
• Enhance gut lining and reduce the risk of leaky gut, which is the root of serious health conditions like auto-immune, etc
• Increases Immunity

Twisting asanas

1. Seated Twist (Ardha Matsyendrasana
2. Revolved Triangle Pose (Parivrtta Trikonasana)  

• Wind-Relieving Pose (Pavanamuktasana)   
• Seated Forward Bend (Paschimottanasana)
• Cat-Cow Pose (Marjaryasana-Bitilasana)
• Cobra Pose (Bhujangasana)
• Bow Pose (Dhanurasana)
• Half Lord of the Fishes Pose (Ardha Matsyendrasana)
• Child’s Pose (Balasana)

• Thunderbolt Pose (Vajrasana)                      

These provide a gentle message to the abdominal organs, which stimulates digestion and excretion. Asanas enhance blood flow to the digestive tract, enhance peristaltic movement, thereby leading to better gut health. These asanas reduce bloating, & gas.

Pranayama for Digestion

Kapalabhati and Bhastrika (Bellows Breath) 

• Increase blood circulation in the stomach
• Improve digestion.
• Boost metabolism
• Reduces digestive discomfort.

6. The Endocrine System and Yoga

The endocrine system is responsible for secreting hormones, which are chemical messengers that regulate a wide variety of bodily functions, including growth, metabolism, and reproduction.

Effect of anatomy-informed Yoga on the Endocrine System

The endocrine system is responsible for the secretion of hormones, which are responsible for regulating essential body functions like growth, metabolism, and reproduction. These hormones are like chemical messengers. Yoga can have a profound effect on the endocrine system by reducing stress & cortisol levels in the blood and promoting the release of healing hormones like endorphins.

Stress reduction:

Chronic stress can cause malfunctioning of these chemical messengers, which manifests in the form of hormonal imbalances. These hormonal imbalances obstruct body functions like growth, reproduction, etc.

• Meditation
• Nada Yoga
• Corpse pose, child pose
• Om Chanting
• Yogic Nidra

All these activities help in reducing stress and maintaining healthy hormonal health.

Asanas that directly affect the health of the Endocrine Glands:

• Fish Pose (Matsyasana) affects the thyroid gland, thereby regulating metabolism and energy levels in the body.
• Headstand (Sirsasana) helps regulate hormones by positively affecting the pineal and pituitary glands.

7. The respiratory system and Yoga:

The respiratory system consists of the lungs, the bronchial tube, the nose, the larynx, the pharynx, and the trachea. It is mainly responsible for supplying oxygen and eliminating carbon dioxide from the system. Various diseases related to the respiratory system are Asthma, Bronchitis, Allergies, Various types of Flu, Pneumonia, Chronic Obstructive Pulmonary disease, and so on.

Effect of anatomy-informed Yoga on the Respiratory System

1)Respiratory rate is slowed. Breath becomes slower and deeper.

2)Oxygen absorption capacity by the lungs improves.

3) The diaphragm is strengthened.

4)Impurities in the nasal passages, lungs, and airways are removed. Air is purified, and hence, cells receive pure oxygen.

Asanas and Pranayama, which enhance respiratory health

The below asanas work by expanding the chest, & strengthening the lungs. The diaphragm becomes stronger.

1. Bhujang Asana (Cobra Pose)

2. Matsya Asana (Fish pose) 

3. Padma Sarvangasana: The Inverted lotus pose

4.Ardha Matsyendra Asana

5.Sukh asana

6. Nadi Sodhanam Pranyama

7. Kapalbhati

8. Bhramri

8.The Excretory system and Yoga

Removal of waste products of metabolism from the system is known as excretion, and the system responsible for removing the waste products is known as the excretory system. The excretory system consists of the kidneys, lungs, skin, large intestine, and liver.

Effect of anatomy-informed Yoga on the Excretory System

It helps in the effective removal of waste products from the system, both at the physical and mental levels. Yoga works on the excretory system by improving blood circulation, & toning the organs. Yoga also helps in the purification of the mind and emotions. Below are asanas that help in massaging the kidneys, improving blood circulation in and around the kidneys, & increasing the capacity of the kidneys.

• ASANAS

1. Sarvanga Asana
2. Bhujanga Asana
3. Dhanur Asana
4. Ardhamatsyendra Asana
5. Hala Asana

 PRANYAMA  – Belly Breathing

In abdominal breathing, the diaphragm and kidneys go down. It then helps in massaging and toning the kidneys. Pranayama also helps in blood circulation.

Yoga has a positive impact on the hypothalamus and parathyroid glands, which helps in electrolyte balance, PH balance, and maintenance of homeostasis.
