What a MORON! sorry had to say it. Sprinters brought the same amount of food as the long distnace runner back to the fire? ???? Uhhm.. got news for you buddy, humans had to chase down their food for miles and miles and even days! Sprinters do not and will never have the stamina to chase food down (thank god for fast food!) so to say that the sprinters look like greek gods for a reason? LOL! there is a reason sprinters will never run past 200m, why? THEY CAN’T !!! too much body weight to carry. I am not saying that a sprinter is healthier than a marathoner or visa versa (that is a whole other topic) get your facts straight before you start preaching about how to exercise. Cardio is the staple of human existance! without it, our hearts and vascular system will only get weaker with time. Feel sorry for your clients as they are being feed a bunch of horse shit information. I will stop my ranting but if you would like to continue via phone or even publicly, I would love to have a debate with you via radio :)

I actually agree with alot of what he said.
I personally think there is a lot of confusion between aerobic, cardio and endurance training. The problem is, most people think it refers to the same thing – endurance training.
While I have the utmost respect for people who enjoy or compete in endurance events (long distance running, cycling, swimming..etc.) as a sport, I don’t agree with the notion that running for hours on end is the “staple” of human existance.
Our bodies evolved over millions of years, and for almost all of that time we were living as hunter-gatherers. Our lives centered on hunting wild animals, gathering nuts, fruits and root vegetables, and avoiding getting hurt by other predators.
That means our physical activity was focused on short bursts of exertion followed by rest. The only thing “extreme” about it would have been the rare time you would need to run for an hour straight. And you would never have jumped up and down repeatedly like Richard Simmons.
When hunters hunt, they walk for hours NOT run or chase, and only when they are moving in on their prey or confronted by another predator do they run, sprint or fight. And these bursts of exertion are short-lived and followed by rest.
It’s true in the animal kingdom, too. When animals fight or run, it’s a short burst of energy. It’s never an extended, medium-intensity effort, like when you’re jogging.
All of your body’s mechanics are tuned to this short burst of activity.
Your body is not designed for long-duration activity, your heart and lungs lose their ability for maximum, peak performance.
This is the trade-off you make when your body has to adapt to this unnatural type of exercise. Your body stores fat and loses muscle as it tries to cope with running for long periods or other types of cardio or aerobics, that’s why people who do a lot of aerobic endurance work are built the way they are.
When you exercise within your aerobic limit, you don’t improve your aerobic capacity. That’s because it trains your heart, lungs and muscles to work at a certain level (you run a lot, you become more efficient at it).
I think a lot of people here aren’t gonna like this, especially if you’re an avid runner. But to dismiss this as bullshit is just being short sighted.
Just to add to the mix
I know a lot of you won’t agree with this, but I think it makes perfect sense when you really look into it.

“I will stop my ranting but if you would like to continue via phone or even publicly, I would love to have a debate with you via radio :)”
haha…good debating there – one word answer!
I listened to the interview too and I have to say I have to agree with Renegrade’s comments above. Jason Sieb is clearly knowledgeable about human physiology and is a successful personal trainer. To call him a moron is unfair and to be frank you make a pretty weak argument against his views! Maybe you should do some research to back up your statements rather than be quick to dismiss something just because it goes against mainstream thinking!

Antilock- miles and miles and even days? Really? Perhaps you should check out the effect of ultra-endurance activities on sarcoplasmic reticulum and its ability to regulate Ca2+ levels correctly. Just sayin….humans were NOT designed for distance. -EK

Agree completely Eric.
Unfortunately a lot of endurance guys and girls don’t want to hear it. I have a lot of respect for people who compete in marathons or extreme endurance events..etc. as I know I couldn’t do it (nor would I want to).
In spite of getting the advice to do aerobics or cardio from your doctor or trainer, I think there is a big misconception that these type of activities improve the health of our heart and lungs.
This type of exercise does make the heart and lungs more EFFICIENT no doubt, but actually reduces their reserve capacity.
Simply put, reserve capacity means your heart has the ability to pump more blood, faster in times of stress. Reserve capacity for your lungs allows them to deal with high exertion like lifting, carrying, running/sprinting or going up stairs.
When you exercise continuously for more than 10 minutes without rest periods, your heart adapts by becoming more efficient. However, It achieves this efficiency through downsizing – smaller muscles, smaller heart and smaller lungs.
The cardiovascular system becomes very good at handling a 60-minute jog, but it gives up the ability to rapidly provide you with big bursts of energy for short periods.
Again, this isn’t to dismiss endurance training completely if that’s what you enjoy, but I don’t think people should be so quick to jump to conclusions when someone goes against mainstream thinking that aerobics are wonderful. Ultra endurance activities are extreme and if we were designed for running miles and miles we would no doubt have four legs :-)
There was a dude named Jim Fixx who was a popular fitness guru of the 70’s who like many, claimed that the secret to heart health and long life was endurance running – up until he died of a heart attack – while running!
Make of that what you will.

Hey Hunter – It’s great that you have a new podcast! The guests look interesting. I heard an interview with Jason on Jimmy Moore’s show too (I think). I listen to so many podcasts . . .
Anyhow, what happened to the Eat Smart for Life Podcast? How is Brent doing?
