From the previous analysis of muscular actions, it’s clear that with it takes to get into this pose is almost completely the opposite of what it takes to remain in it. Lifting the weight of the body into spinal extension requires a strong, integrated action of the arms and spinal extensors. Once past vertical, gravity will pull the weight of the body into extension, so the trunk flexors must kick in to prevent hyperextension. Therefore, based on their balance of strength and flexibility in the extensors and flexor muscle groups, some people may have the ability to get into full locust, but not to sustain it; whereas others can’t get there themselves, but can stay there if assisted into the pose.
