Ten years ago when we said "you need 60 minutes of moderate to high intensity exercise a day" the world protested. Ten years ago our society was still some what "active" during the day. We didn't have smartphones, iPads, electronic billing, one stop shopping at our fingertips, we actually had to move our bodies around in order to get things done. Well, those days are over. The majority of our population sits and sits all day. They don't have to move, everything is right there at their finger tips.
So today when we say you need to workout 60 minutes a day everyday, everyone still freaks out.
SIXTY MINUTES OF MOVING MY BODY? NO WAY: It's too uncomfortable, it takes too much effort, too much energy, and besides, I may miss a text message.
So do we really need 60 minutes a day? Personally Yes, but No if people would simply MOVE more throughout their day. But they don't and we are becoming obese and more over weight by the day.
The concept of time is daunting, the concept of actually moving for 60 minutes can seem overwhelming but let's look at it from the other angle, sitting all day is worse, yet nobody complains when they have to do it.
