Hamstrings(lengthening)

While still primarily lengthening, the forearms-down position can subtly shift the pelvis higher relative to the shoulders, potentially intensifying the stretch sensation in the hamstrings, particularly near their origin. This encourages a deeper release in the posterior chain, allowing the hips to lift more freely and further decompressing the lower spine. The quality of length becomes less about pushing back through the hands and more about drawing the sit bones skyward from a stable forearm foundation.

Deltoids(stabilizing and lengthening)

The deltoids, particularly the posterior and middle heads, move from a primarily stabilizing and supportive role to one that emphasizes deep lengthening and release. With the forearms grounded, the humerus is encouraged into a more pronounced internal rotation, allowing the shoulder blades to broaden and the upper back to open. This creates an intense, yet therapeutic, stretch across the shoulder joint, fostering both mobility and a sense of release in this often-restricted area.

Triceps Brachii(isometric stabilizing)

In the forearm variation, the triceps brachii shift significantly from their primary role of actively extending the elbow in the root pose. Here, they engage isometrically to stabilize the elbow joint, pressing the forearms firmly into the earth and preventing collapse. This sustained, subtle activation builds endurance and proprioceptive awareness around the elbow, offering a different quality of strength compared to the dynamic extension required in the full hand-supported version.

Wrist Injury / Carpal Tunnel

Weight-bearing or extended wrist positions can compress the median nerve and aggravate inflamed tendons, worsening pain and causing numbness.

Practise a forearm inversion (Pincha Mayurasana) instead, or use a wall-supported headstand to remove wrist load entirely.

Shoulder Injury

Overhead loading and extreme shoulder rotation can impinge the subacromial space and overload rotator cuff tendons.

Avoid weight-bearing inversions entirely; practise supported Setu Bandha or Viparita Karani as an alternative.

High Blood Pressure

Vigorous effort and inverted positions temporarily raise blood pressure in the head, increasing strain on blood vessels.

Avoid this inversion entirely or keep the head above heart level at all times; never hold the breath.

Pregnancy

Deep twists, abdominal compression, and lying flat on the back can restrict blood flow or cause discomfort as pregnancy progresses.

Avoid all inversions unless already well-established in the practice and with teacher supervision; use a wall-supported legs-up-the-wall instead.
