I shall have to add wall sits to my repertoire. As it is I go out into the hangar at work and bust out 20 push-ups, & 20 sit-ups once an hour to deal with stress, and to get away from my desk for a few minutes. The occasional wall sit might be worth a go.
I generally do a five minute a couple times a day and it helps with my balance. Not to mention that just being still and concentrating on slow rhythmic breathing calms and centers you. If I have a meeting I do at least a couple of minutes. The key is not to think about what is going to happen or what you are going to say. Just kind of float.
I haven’t done wall sits since my 7th grade science teacher suggested it in place of the paddle. He said sit the wall for two minutes or get the board!
