Alignment based movement is even more important when you're practicing challenging compact arm balances like Crow (Bakasana).
If you're looking to introduce arm balancing into your practice, play in this short tutorial that guides you into crow pose, the gateway into many other arm balances.
Build strength, confidence and trust in your own strength - and as Mari says, play in the edges of fear.
If you have wrist and shoulder sensitives, please take note of Mari's alternate options to build strength without having to weight-bear.
You'll need a yoga mat and yoga blocks (or something that is a little bit elevated that you have around your home) for this tutorial. Keep your blocks near by and happy arm balancing!
