I came across this amusing article on one of the many health and fitness sites I follow. Having been in the industry for almost three decades, I really have seen it all. Including all sixteen of these faux pas. Rather sheepishly I have to admit that I am sometimes guilty of #11 - in fact, I use my cardio time to multitask on my tablet or catch up on my reading. This works for elliptical or stationary bike, but not so much for treadmill running.
What do you think?
