There are 168 Hours in a week.
We sleep, on average, for 56 (8 hours a night)
We sit and work for 45 (9 hours a day, 5 days a week)
We sit and commute for 10 (1 hour each way, 5 days a week)
We sit eating, reading or watching TV for 21 (3 hours a day, 7 days a week)
That leaves 36 hours to do other things, mostly at the weekend.
That which we do the most of, we become.
An hours exercise or movement a day really doesn’t seem much to ask does it? And if you recieve treatment for half an hour a week and change nothing else, how can you expect it to work?
