    Thanks Damer, that does answer! And it makes perfect sense!

      The pressure, the pressure! But no, I think I'm done. For this time.


        Damer I have a question about walking (regarding monthly challenge but trying to generalize for everyday use). If I am at last day where I get to walk 1h30, can I break it down into two 45' walks or three 30'? I am pretty sure I can maintain higher speed that way and it fits my working/house choring schedule. In general, are shorter walks equally beneficial for CV and calorie burn, considering we keep same total duration? Does it really help if I walk shortly after eating?


          Hahahahahaha GiorgosD. Trust you to ask a question that requires a lot of answering.

          So, here goes. The debate (if any debate is being had at all) between walking and other forms of CV has to do with intensity vs duration. Is 100m sprinted ten times equal to 1km ran once? The answer is, obviously, no. To understand why we can't easily substitute duration for intensity consider, again, the example of 100m sprinted 10 times. The physiological (and psychological) pressure applied on us by each activity is different and the physiological adaptations that result from that are also different.

          So, to get back to the specifics of your question: Can you chunk up the one and a half hours of walking into shorter chunks and maybe up the intensity during at least some of them so you still make the total time? Yes, you can. Is it the same? No, it is not. Is it better or worse? No one can answer that, exactly. It is different.

          Every time we exercise, even for a minute, we create a massive number of neurochemical changes in our bloodstream and in our gut. These, in turn, affect our hormonal profile and the way the body manages the energy that is available to it and this, in turn, creates neurobiological changes in us which lead to longer lasting physical adaptations. Consider that, all things being equal, we are in a different emotional, psychological and biological phase in different parts of the day.

          During exercise the brain is in communication with different organs which also 'talk' to the body and each other. This creates a complex web of interactions which is why it is so hard to be prescriptive with exercise plans. What works for one person does not, necessarily, work for another.

          The trick, always, is to move your body and do the best you can sustainably. So, if you workout a 'plan' that allows you to do that go for it. There is no perfect and everything is a compromise of some kind. The magic is to do things sustainably.

          I hope this helps.


            And just like that, this thread is over. As usual you had some amazing questions which allowed me to broaden the horizon in terms of what we know.

            A big "Thank You!" to everyone who took part in this.

            Until next time, stay safe, stay true and stay awesome.
