Today I achieved adho mukha vrksasana (handstand) pose against a wall without someone to assist.
There are two types of balance, namely dynamic balance and static balance. Dynamic balances are more challenging, and beginners should only start their practice with static balances. Handstand is an advanced mild backbend pose that incorporates both types of balance, and the challenge of beginning handstand is to overcome the dynamic balancing act of getting the feet up before staying in the static balance of the pose.
The ability to perform adho mukha vrksasana requires abdominal and back strength, and hip and back flexibility, developed over much time on various dynamic vinyāsa exercises. The ability to stay in the handstand requires arm stability, and regular practice of this challenging pose. One day, I would like to be able to do handstand push-ups.
Handstand push-ups will build bicep strength to support lowering the body into flying crane from handstand pike, and from flying crane into čaturanga dandasana.
