Everyone should read this

JMBS, did you exclude your head from your avatar so you can't join Yet, Virt, Veg and myself in the photoshop competition in the other thread? That's cheating!!

I agree with you guys though, there's nothing more boring than walking or doing a slow jog on a treadmill for an hour. HIIT is much funner and gets it done easier.

It's hard to fit my beautiful face and awesome bod in such a small avi.  I guess my body (and my head, ha ha!) are too big!  Today the body wins!  ;)

This seems like a very informative link. I will be sure to read it when I have the time.

I read part one the other night and wrote half a page in this thread, was about to click post, and then
THE BROWSER SHAT ITSELF!

I was so pissed... But lemme try summarize the point I had in mind. But before that, I'll post this pic which I feel is relevant:

As you can see above.
DHEAs produce sex hormones, and pregnenolone produces stress hormones. Both of which come from cholestrol which is at the root of all hormones.

This is a huge reason as to why you should never take cholestrol-lowering statin drugs.
Your body has high cholestrol because it's stressed, not the other way around (your body is stressed because it has high cholestrol). So if you have high cholestrol you should focus on limiting your physical and psychological and environmental stressors, not fight your body's natural way of treating it (your body producing more cholestrol is its way of fighting stress).

A bit random, and probably scattered, but I thought I'd throw that useful piece of information out there.

ANYWAY...

I read part one and I really enjoyed it. It was an excellent read and I appreciate that it was backed up by some hard evidence. Very eye-opening. I've always loved the world of hormones/diet.

It's important to note that we are quite literally what we eat - Every single cell in our bodies is made up of what we consume. Every single hormone released into our body is made from the quality of the foods we eat.

I'll make a post later regarding why I'm skeptical about one particular part of the article - relating to post-workout nutrition.

But overall, great article. I gotta run.

Yeah, I'd much rather go hiking or take a spin on my bike than be on a treadmill like a gerbil for an hour.

I'm with you on that, but just to be sure we're on the same page, those would qualify as LISS also, not HIIT.

What's LISS?  Low intensity something, I'm sure.  MVP said that as a guy w/high metabolism, I might benefit more from old-school cardio that HIIT, if I'm understanding him right.

LISS = Low intensity steady state.  You'll do fine with either one, it's probably even better if you switch it up and do a little of both.  But just do the work.

By the way, MVP.. I remember reading earlier today... Somewhere you said that HIIT has a high chance of burning muscle for energy.  But I've been under the impression that one of the pros of HIIT is that it's much less catabolic than LISS, so what's the deal?

edit: 
sorry to jack the thread.  i intend to get back on topic after i've gotten through all three pages.

Snatchula,
   MVP, correct me if I'm wrong.  HIIT has the risk of being catabolic, but since you're doing it for less time than LISS, time in the catabolic state is reduced.

Done properly, there is nothing catabolic about HIIT.

The trick is to stop just short.  I would even go so far as to say avoiding catabolism at all costs is contraindicated in a sound approach to fitness and overall health.  Your body's natural recovery from such a state is a strengthening process in itself.

To some degree, occasional catabolism is inevitable (especially when you're forcing your body to retain more muscle mass that it deems metabolically affordable).  Not saying you should dally around in a chronic state of catabolism, just don't have puppies if it happens occasionally.

You burn more energy. The time is irrelevant, that's the whole benefit to HIIT. It increases your metabolic rate and keeps you in a fat burning mode, a high energy mode so to speak. Which can cost you more muscle.

HIIT is a heaps better form of exercise (IF YOU'RE CONDITIONED TO IT) because of the EPOC - Excess Post-exercise Oxygen Consumption.

Now to put that as simply as I can:
Your body has an increased demand for oxygen, and thus elevates your heartbeat and metabolism for up to, above or beyond 48 hours.

Same goes for Resistance Training though. They both have high EPOC that's why they're more arising in the health/fitness world to steady state cardio.

In terms of just HIIT to steady state cardio though, here's the main difference with results....
Steady state cardio is focused on how much energy you can expend there and then.
Wheras HIIT is focused on how much energy you can expend for up to 2 days after you finish that quick bout of intense exercise.
And in the end because HIIT keeps your heartrate up for a significantly longer amount of time after the training, it's a much more ideal option.

They are both extremely catabolic in nature, but your body adapts and thus (as Veg said) strengthens itself in the process.
Your muscles strengthen and adapt to keep up with your training and your body's endurance, core, posture and lungs become conditioned to HIIT.

I was very skeptical about HIIT in the beginning, but having done the research, I've seen the light.

And just to throw it out there:

Keeping your metabolism up is a good thing. Your body is constantly metabolizing energy. Even if you wanna bulk up, just eat more to accommodate it because the higher your metabolism is naturally then the more bodyfat it'll burn off.

Plus, no one should be so fussy about HIIT being catabolic considering the nature of resistance training. :p

Wyrms,
   That's pretty much how I understood HIIT.  And resistance principles cross over nicely to HIIT, correct:  Progressive resistance, muscle confusion via frequent changes to intensity level, muscles worked via different equipment, interval timing, length of session.  Correct?

Thinking about all those elements individually and comparing them from resistance training to HIIT, yes! All good, all correct.

You're spot-on. =]
