It’s a great way for newcomers to get familiar with the feeling of supporting all of their weight on their hands before attempting a freestanding handstand or other more advanced maneuvers.
This posture, sometimes referred to as “frog stand” in other disciplines, improves balance and stability while it strengthens the arms, shoulders and core. The crow pose also helps build strength in the hands, fingers and wrists.
There are many other variations on this pose as well, such as the side crow, one leg crow and even a one arm/one leg crow.
Start with the basic version and work your way up to the others from there.
