Yogis: protect your wrists by perfecting your pose

Hey yogis, do you find that yoga is hard on your wrists? I sure do. All those downward dogs and upward dogs and the occasional crow pose leave my wrists aching to the point where I feel like I can't take it anymore and have to retreat to child's pose. Fitsugar has recently addresses this issue, and they have the following suggestions:

• In poses like downward dog, where there's a lot of weight on your wrists, make sure put some of the weight in your hands too. Each of your knuckles and each of your finger tips should be digging into the mat, but the undersides of your fingers don't have to be touching. Make sure the weight isn't concentrated on the pinky side on your hand. It will make a huge difference.
• Move slowly and take a break when your wrists are screaming.
  
• Try some wrist stretches.
• Ice your wrists if they need it.
  

I'll have to try these the next time I'm at yoga class. Do you have any other suggestions?
