My job can be very sedentary at times. Doing PT on my patient isnt really exercise and though I do a fair amount of lifting I don't count this. Maybe I shoulld. Much time is spent sitting. So I took the advice of Tom Venuto and this is what I did this past week. Instead of sitting I stood for short periods, I paced while I read, also did my yoga that didnt require any floor work, did lunges and weight training warm up exercises several times a day. I felt better, not so stiff from sitting and felt like I was accomplishing something.
