BTW.. I tried Pure (01) & Planet (03) (all 1 yr-4 lessons per week) before ge... Apr 06 just rejoined!
or maybe good instructors in Planet la.. they will correct me the right positions, how to do alive pose not death pose (this morning informed by instructor)!
In fact I also feel if you attend more, you'll get more, cos everytime I can learnt a lot from the instructors!
re : tail bone
I'll put a towel on the floor first, it would let you feel better (my tail bone got hurt a many many years ago!). Or maybe try to use your buttocks (lower part) to touch on the floor only (small area).
