5 yoga alignment mistakes causing injury: knee hyperextension, lumbar rounding in forward folds, wrist misalignment, shoulder impingement, and neck compression in inversions.
- 121% of yoga practitioners report a yoga-related injury requiring medical attention — most caused by correctable alignment errors
- 2Knee hyperextension in standing poses places excessive stress on the ACL and patellar tendon
- 3Lumbar rounding in forward folds is often accepted as a flexibility limitation rather than identified as an alignment error
- 4Internal shoulder rotation in overhead poses is invisible from the front of the class
- 5Neck compression in inversions is the most serious yoga alignment error and can cause cervical spine injury
Why Yoga Injuries Are Underreported
Research published in the Journal of Bodywork and Movement Therapies found that 21% of yoga practitioners report a yoga-related injury that required medical attention, with the lower back, shoulder, and knee being the most commonly affected areas.
Mistake 1: Hyperextending the Knees in Standing Poses
What it is: In standing poses like Warrior I, Warrior II, and Triangle, the front knee should be directly over the ankle — not extending past the toes. Knee hyperextension places excessive stress on the ACL and patellar tendon.
What AI measures: AI measures horizontal distance between knee and ankle landmarks in standing poses, flagging knee extension greater than 2 cm past the ankle.
The fix: The knee over ankle cue — in every standing pose, check that the front knee is directly above the ankle when viewed from the side.
Mistake 2: Collapsing the Lower Back in Forward Folds
What it is: Lumbar rounding in forward folds places the intervertebral discs under posterior stress and is a primary cause of yoga-related lower back pain.
What AI measures: AI measures lumbar spine angle relative to the pelvis in forward fold positions, flagging lumbar flexion greater than 15° beyond neutral.
The fix: The long spine cue — prioritise length in the spine over depth of the fold. Bend the knees if necessary to maintain a neutral lower back.
Mistake 3: Wrist Alignment in Weight-Bearing Poses
What it is: In poses like Downward Dog, Plank, and Chaturanga, wrist misalignment concentrates stress on specific wrist structures and is a primary cause of yoga-related wrist pain.
What AI measures: AI measures the angle of the hand relative to the forearm in weight-bearing poses, flagging wrist rotation greater than 15° from neutral.
The fix: Place hands with middle fingers pointing directly forward and spread the fingers wide. Press evenly through the entire palm.
Mistake 4: Shoulder Impingement in Overhead Poses
What it is: Internal shoulder rotation in overhead poses (the most common default) creates shoulder impingement and is a primary cause of yoga-related shoulder pain.
What AI measures: AI measures rotation of the upper arm relative to the shoulder joint in overhead positions, flagging internal rotation greater than 10° in poses that require external rotation.
The fix: The thumbs forward cue — rotate the thumbs toward the front of the room (external rotation) before raising the arms overhead.
Mistake 5: Neck Compression in Inversions
What it is: Neck compression in inversions is a primary cause of cervical spine injury in yoga.
What AI measures: AI measures the angle of the cervical spine relative to the vertical in inversion poses, flagging neck flexion greater than 20° or extension greater than 10° from neutral.
The fix: Shoulderstand should be performed with weight on the shoulders, not the neck. Headstand should be performed with the majority of weight on the arms, not the head.

Frequently Asked Questions
The most common yoga injuries affect the lower back, shoulders, wrists, and knees. AI pose estimation identifies the specific alignment errors causing these injuries before pain begins.
Wrist protection requires correct hand placement (middle fingers pointing forward, fingers spread wide) and even weight distribution across the entire palm. AI analysis measures wrist angle in weight-bearing poses.
Lower back pain after yoga is most commonly caused by lumbar rounding in forward folds or hyperextension in backbends. AI analysis measures lumbar angle throughout poses.
