The Spine Strengthening Series in Bikram Yoga Series does just as its name suggests and helps strengthen the spine. It is a group of four postures at two sets, each between Wind Removing Pose and Fixed Firm. These are the only set of postures done while laying on your stomach and can be pretty demanding if you are not breathing in it.
The Spine Strengthening comprises four poses that are in order as follows: Cobra, Locust, Full Locust, and Floor Bow. Each of these postures works on different spine sections and has immense healing and strengthening properties. Between postures, you take turns looking to the side of the room with the ear on the towel with the palms facing the ceiling. After the first set, look to the right and after the second set, look to the left. I will go through each posture in the Spine Strengthening Series in-depth in this post, so let's get started.
