Comment is vague, but apparently what you are suggesting is that physical fitness isn't safe without using a computer. Our bodies evolved to run, and it is, actually, possible to recognize and react to what the body reports to the brain through sensation without any intermediary electronic device gathering and reporting false data. Many are capable of sensing injury or illness before overt symptoms appear, and react accordingly, reducing or eliminating negative impact. The more computerized devices are relied on for ordinary activity, the more they become a crutch, and the more difficult it becomes to operate without them. Obsession is unmistakably unhealthy.
No, what they're saying is that exercise as you've described, will lead to injury and goes against ALL the traning advice of seasoned long-distance runners.
Then they, as you, have entirely missed the point of my comment, which had nothing whatsoever to do with any exercise plan. I was instead cautioning against unnecessary reliance on affectation.
