The only way to get better is to practice, practice, practice. And then practice some more. My newest project is this hummingbird pose (sometimes called dragonfly pose). It's a great arm balance that uses core strength and the hips. I've got a long way to go on it- need to try to get my shoulders even and get that foot higher on my tricep so I'll continue to practice, practice practice. And then practice some more.
I'd love to know what you're working on- leave a comment below or tweet me.
