I think it’s fair to say that the majority of people on the 9-5 grind will be sitting down a lot. Almost the entire day. Which is not very healthy at all.
According to a study conducted by the Annals of Internal Medicine, people who sit at desk jobs all day were found to be twice as likely to die early, even with regular exercise.
Even with the best intentions, like walking around every hour or taking frequent breaks you'll still spend the majority of your time desk dwelling. And unless you’re in a progressive office with stand up desks, this is kind of hard to avoid.
There's a couple of things that will happen when you are hunched over a desk all day. Tight hips and legs, a weak core, and possibly even imbalances in your neck, upper back and chest muscles.
You may even be prone to cramps or aches during work. Don't ignore those signs, it's your body’s way of protesting.
