Re: Hard to Stay in Seiza
Make sure the weight is even over the part of the leg in contact with the mat. So the weight is 50/50 between your feet and knees.
Also, seiza is a a pain, everyone hates long seasons of seiza and it hurts everyone sooner or later, you just have to learn to deal/cope with it.
Sorry to sound harsh but once you conquer seiza it isn't a worry even for those times when Sensei decides to talk for 30 minutes.
