GOOD Health Myths Debunked: Fitness

Is running outdoors better than running on a treadmill? Should you exercise on an empty stomach? Holly Perkins helps GOOD bust health myths.
Who am I?
I got interested in marketing health products online about 8 years ago. Online business has always fascinated me. After studying natural medicine for 3 years in the German Paracelsus School in West Germany, it was clear to me that I would, in what way ever, always be involved in the health and fitness Industry. When I heard how many people are really searching online because they need advice or a particular product, I decided to set up this blog. I do really believe that we are not only what we eat, but also what we absorb. There are tons of great, cheap e-books out there that give solid information about healthy foods, super foods, dieting, fitness in general, well being etc. etc. You can see one of my information product stores here: Information Products This is where my customers can download top quality e-books and audio books on these topics. If you don't change what you are doing today, all your tomorrows will look like yesterdays!
And do you honestly think a physicist would agree with you?
No, because what we’re talking about here is a fact and in this case you’re wrong about the physics.
You shift the center of the weight because you move in relation to the GROUND (the ground that’s rolling in the treadmill), not the world around.
We should hear from a phisicist.
If you would move your center of weight forward when running on a treadmill you would tumble forward. As long as YOUR mass is going forward in relation to the WORLD (NOT the ground) you will have to shift the center of the weight, not on the treadmill because the treadmill’s “ground” is going backward in the same speed as you’re going forward (in relation to the “ground” of the treadmill), that prevents you from going forward in relation to the world.
Imagine a race track, one meter wide, infinitely long. Add a runner on the track. You don’t see any background, no ‘world’ around it (for arguments sake), just ‘space’ :>
Now, lets assume the track is fixed (as in running outside) and the runner… runs, with some speed v.
Secondly, lets assume the runner stops and the track itself is pulled back with speed v. The runner has to start running so that he doesn’t fall or doesn’t get pulled back with the track.
continuation of the previous…
His movements while running in both cases are identical (the start may be a bit different). In both cases the runner is moving in relation to the track.

I get your point, but in this case when you run outside there “is” a world. When you run on the track at speed v, you have to run twice as fast to get forward at speed v (in relation to the world) when the track starts rolling back at speed v. So the issue with a treadmill is that if you run at speed v on a track that rolls back at speed v you won’t get anywhere in relation to the world which means you don’t have to shift the center of your weight.
Ok I think we’re getting closer to a consensus. The thing is, in the outdoor case, the track is a part of the world around.
Relative to the track=relative to the world. This being said, it will be easier to refer to the track only.
In the treadmill case, the track is seperate from everything around (the world doesn’t move with the track). Again, let’s seperate those things and refer only to the track also in the treadmill case.
We don’t need the world anymore;) Any Eureka!’s yet, Hejzwej?:)

On a treadmill you are not pushing forward, you’re pushing up. you could essentially do the same thing by hopping instead of running.
The treadmill also forces you to do the running movements. That’s what I’m trying to say… and no I don’t have any “Eurekas” because it’s common sense. The human body isn’t designed to be running on a track that helps you to get forward.
You could try it yourself…
Whether you do the same workout on a treadmill or outside, you still won’t see the same results. Running outside “is” healthier.
Aah hejzwej… You don’t understand physics, plus I think you don’t jog anyway;)
Running outside is healthier I agree, but running mechanics/movements on a treadmill and a fixed track are the same. This is where we differ for now, in the future maybe someone will explain this better than I could:)
Does anyone eat junk food while running on the treadmill?
If the treadmill didn’t offer resistance (think of a slippery carpet.) then there would be a weight balance problem since you aren’t moving forward.
However, if you push back hard on the treadmill, you shouldn’t be able to make it accelerate so this is not the case and those saying that the treadmill and outside dynamics are the same are essentially correct.
However, there are definitely differences in the softness of the ground etc that make running on a treadmill different.
who paid this girl to say this?
I am a marathoner and, let me tell know, she is not even half right!
sessions should last 70-90 minutes?
Aww man i’ve only been doing 30.
@daskriege If you are air-conditioning your shit, your doing it wrong.
@EFESORJM Which part of is wrong?
i’d hit it
I am also a marathon runner and weight lifter, one who used to be obese and weak, and I found everything she said to be exactly true.
What points do you think were wrong?
Could you go into more depth with where she’s wrong? Just because you CAN run marathons does not mean you understand how the body works.
shes hot
Bad myth there….you need carbs for energy huh? Bull crap. You go a head and keep eating your grains….good luck with that crap. You should know if you are an expert that the human body was not designed to eat grains! Cows and animals with more than one stomach are made to eat grains. Working out in a fasted state is proven time and time again…..I do it……1000′s do it and it works….there is plenty of research out there. Quit listening to conventional wisdom!
She didn’t say that you need carbs for your energy. You just need some kind of energy and our bodies get that from food. Working out on an empty stomach may make you skinny, but it will make you lose muscle mass which is not a good thing.
She’s good-looking! Red-haired woman!
@ajcurly sorry for replying for and old comment but STOP being so stupid,60% of your energy should come from carbs,yes grain is a major source of carbs and yes we are not realy made to eat raw grains but we dont eat it raw and there are tons of other carbs sources like fruits and vegetables wich we can easly digest since we are primates,also cows are not realy made to eat grains they have 4 stomachs because it needs to get everything from the low nutrion grass and other vegetations.
