Assume a prone position on the floor, supporting your weight on your hands and toes. Hands underneath your shoulders, and legs extended behind your in a wide stance.
Hips low, keep your glutei engaged and push away from the floor with straight arms. Eyes forwards, neck neutral and try to lengthen the spine.
Then push the hips back, keeping your arms straight. Elevate the shoulders, (shrug them up to our ears), & keep your neck neutral. Think about pushing your chest through to the floor.
Hold for a short time, before returning the cobra position.
