Thanks for your encouragement!
We only had a two-day seminar and my body aches everywhere and I've got tons of bruises. I survived, but, during regular class yesterday, couldn't "produce" much "kime". We were all very tired and Sensei took pity on us by giving us only 'soft' things to do.
But...4 and 6-day seminars?
After reading your posts I suddenly feel in better shape.
