Reverse warrior posture is one of the foundation poses for many yoga practices and is one of my favorites. It just feels so good to get that deep stretch through the side body while strengthening your legs. Although as with all yoga poses, alignment is crucial for this posture or lower back injuries can be created or exacerbated. There is so much going on in this posture that it can be easy to forget to engage your abdomen as you lean back and yet it is crucial to remember this to protect your lower back.
In this posture you are not just leaning to one side but your also leaning back. This oblique movement can be compromising to your lower back and should be avoided if you have a recent injury. Even with the healthiest backs, remember that this movement starts and ends in your abs!
