I absolutely love this!
Anyways, I am not into yoga world. I train aikido for 10yrs (and counting) and we have a lot of pressures points and locks on joints meaning the wrists must be flexible and strong. But I went to yoga class and realized how inflexible my body is (to some movements).
So, my wrist joints are kind of strong and flexible, but only inwards since all the techniques involving pushing it that way. Do you know any exercises for outwards flexibility - guess the one with circling would do some job(2nd and 3rd exercise). Also shoulder exercises would be nice in future too!

Anyways thanks for sharing this ;)
Cheers!
