I often hear yogis complain about wrist pain, particularly after a class heavy in planks, chatturangas and arm balances.
The alignment often taught in plank requires the (fore)arms to be at 90 degrees with the palms. Furthermore, in chatturanga, the shoulders move over the wrists, further compressing the angle of the (fore)arm to palm to less than a right angle. This alignment may be too aggressive for some bodies who might feel strain or, even worse, pinching in the wrists when attempting it.
The bad news is that best wrist support for yoga lose flexibility over time, so you should be kind with yourself whenever returning to your mat. The good news is that you can regain some of that flexibility if you practice with awareness toward yourself and follow these easy tips that will protect the wrists, while still promoting opening in areas where there is space available.
