In addition to these videos, I have found that active fingertips, fists (with thumbs OUT!), blocks, and using forearms can alleviate wrist pain! Maybe your Down-dog can be modified into a Dolphin pose or your plank is done on forearms. Modifications are not disabling, they are empowering! Remember, that the goal of the asana is to reap the fullest energetic benefits of the pose, not to be bendy or look perfect. (Yoga is never perfect, that is why it is called a PRACTICE!)
I'll be updating this page with more relevant information over time, so please be sure to check back often!
