I'm establishing a habit of sitting. After a few days of it, I've noticed that at the end of each session I have tension in my shoulders and sometimes during the middle of a 30min sit it gets quite uncomfortable. Do you think this is a posture problem or is it that I'm just not used to being in that particular position? I always get tension in my shoulders when under stress, so it could be related to mind wanderings I suppose.
Also, I would be curious to know of a good timer app for iPhone if anybody uses one.
Thanks for taking the time to help.
