Notes
This posture requires activation of the shoulder extensors, spinal extensors and hip extensors to draw the whole body upwards while the abdomen stays securely on the ground. Stretches the pectoral muscles. Knee extensors activate to kick the legs back into the hands to "tighten the bow" while the legs and chest are simultaneously drawn upwards. It is important to squeeze the gluteal muscles and hamstrings to reduce excessive hyperextension action in the lumbar spine.
​
Leaner patients who experience discomfort as their ASIS presses into the ground may find that a padding e.g. towel, thicker exercises mat may alleviate some of it.
