Introduction to the Main Yoga Muscles

Similar to a sculptor who has complete knowledge of his medium, a yogi should have awareness about the anatomy associated with yoga. Grasping the functionality of key muscles of yoga can prove fruitful in enhancing your routine and provides a safeguard against common injuries.

Upper Body Muscles

The upper body houses a system of muscles that augment stability and flexibility during yoga poses.


Situated around the shoulder, deltoids are crucial for arm rotation and stabilizing the shoulder joint in asanas like Downward-Facing Dog and Chaturanga Dandasana.

Biceps & Triceps

The muscles present in your upper arms, biceps and triceps, play a vital role in bending and extending the forearm. They are involved in almost every yoga pose, more evidently in asanas such as Crow Pose and Upward Dog.


This integral forearm muscle aids in flexing the forearm at the elbow. It is heavily employed during weight-bearing poses like the Downward Dog and Plank.

Rotator Cuff Muscles

Four muscles constitute the rotator cuff – supraspinatus, infraspinatus, teres minor and subscapularis. These muscles are essential for stability and movement of the shoulder joint, contributing significantly to yoga poses that involve shoulder rotation.

Core Muscles

The powerhouse of your body, your core, includes the abs, obliques, and lower back, and is central to maintaining balance and stability in many yoga poses.

Rectus Abdominis

The rectus abdominis muscle or the “abs” is instrumental in balancing and controlling movements during yoga poses. It assists with forward bending and is extensively utilized in poses like Boat Pose.


Located at the abdomen sides, obliques (external and internal) are integral for twisting movements and side bending in yoga. Twisted Triangle Pose and Revolved Side Angle Pose heavily work these muscles.

Transverse Abdominis

The transverse abdominis is the deepest muscle in the abdomen that wraps around the spine, offering stability and support to the lower back, especially during balancing poses.

Lower Body Muscles


The group of muscles known as the quadriceps situated in your thighs plays a vital role in standing and walking. You can feel it in action during yoga poses like Warrior I and Chair Pose.


Located at the back of the thigh, hamstrings are instrumental in forward bends and act as major flexors of the knee. Participating in poses such as Downward Dog and Forward Bends will have these muscles working hard.

Gluteal Muscles

The gluteus family —gluteus maximus, gluteus medius, and gluteus minimus— forms your buttocks. These muscles are utilized in hip rotation, extension, and abduction. Engage them in yoga poses like Bridge Pose and Wheel Pose.

The Significance of Breathing in Yoga

Beyond muscles, breath or ‘prana’ also assumes a critical role in yoga. Pranayama or breathing exercises aids in controlling and focusing the mind, infusing a sense of balance and tranquility.


Attaining deep awareness of the muscles engaged in yoga can aid in systematizing your yoga practice and prevent injuries. Remember, a major part of yoga mastery involves comprehension of the body’s mechanics to ensure mindful and safe practice.
