@Joe Nation,
yes, it was 'picture yourself' type of meditation.... when they told us to think of a person, place, or a thing that makes us happy, i got really angry. they really shouldn't be doing this when they don't know who's in the group. needless to say i burst into tears (silently, for i have decorum) as i have a lot on my plate lately...but it was still highly unprofessional of them to do a meditation not having the first clue about it....aaanyway, i digress.
it's not the technique of crunches, it was my general hiatus that led to a sore neck. for almost 2 months i have not exercised in any regulated manner, what with the moving, which was preceded by a long nasty flu of some sort... so i was fully out of shape. i am now finding out that it's mostly my back and neck that got weak, the rest seems to be quite alright. i'll catch up soon though.
