Many office workers, spend the whole day in a chair staring at a monitor – I do that, as an IT person everything I do require me to sit at a desk and enter information into a computer watching a screen. Sitting all day is not smart, I think humans need to move more.
Sitting all day working in front of a computer, I need to balance that with fitness training. I take long bike rides most of the year, in the wintertime I spend most of my time working on my fitness in the gym. I have a few apps that I use for that.
