HIIT working for me

i was morbidly obece, at 6 ft 5 inches tall it wasnt a nice sight. 2 years ago i lost alot of weight quickly due to crash dieting went from 303lbs down to around 225 losing most of my lean mass that i had underneath. at 225 i still had the same shape body and alot of fat still there, but it was looser and more flabby than before. Ever since then i did the research and started to eat 6 meals, weight train and jog (40mins) throughout the week. i've managed to gain alot of mass back, and lose some fat along the way, but my body shape hadn't really changed, my cardio consisted of 40mins aerobic jogging and nothing else 3 times a week. I have lost fat but very slowly until i started a hard hiit routine (jog and sprints). In 4 weeks my face has changed and my fat is starting to fall off literally, i can see the tops of my abs for the first time in my whole life, i can feel the change in my body shape more in this routine than my other program for me this is really working. Even the stubborn bodyfat that i have had for years is starting to dissapear, the very fat that i've been trying to burn for years is now dropping off thanks to HIIT.
Now don't get me wrong, the sprinting really kills me after 20mins and i don't always look forward to it but the change in my body is more than enough to keep going and its living proof that, for me anyway, it seems to be working. The way i do it is when i think i'm burned out I do one more sprint chanting "you fat bastard" to myself over and over again! until my legs are like jelly.

I hope this has some sort of inspiration

that is a great post-- "you fat bastahd!!" hahahahah

there have been tons of debate on HIIT and you have something to add. I love posters who are actually sweating and doing the deal.

NICE WORK!!! - you "thinner athlete you!"

FF
 
We all probably see this in gym all the time... overweight folks coming in almost on a daily basis, get on the treadmill and walk for an hour, or the stepper/crosstrainer/elliptical on low resistance, again for an hour. Most of them never breaking a sweat. The body composition never seems to change. If you can read a magazine while working out, it ain't a workout!
Glad that your joints are in good condition to allow you to run. It takes a serious attitude to go out and do what you're doing but the results are great.
 
There's a consistent saying you regularly hear: figure out what works for you!

Whether it's HIIT, interval or circuit training....in the end motion & exercise = calories burned. Many dieters neglect to realize the vast difference in their eating & exercise habits from when they were in the reckless stage to their new lifestyle. OMG, today I get bent if I eat a snack-sized Snickers bar...yet back in the day I'd think nothing of eating a full-sized Snickers bar, 5 pieces of pizza, 2 beers and then growing roots for a few hours in front of the tv.

Let's see: eat 6,000 calories, exercise very little....as contrasted to eat 2,200calories and exercise about 12 hours per week. Yeah: HUGE difference.

My trainer/nutritionist/dietician says he's never seen anyone work so hard to lose weight then me...so I can tell ya, it's really this simple:

1 pound of fat = 3,500 calories. In the end, it's calories in vs. calories out. Eat less, move more and you will lose weight. Some lose it faster & easier, some work longer & harder...but in the end, the inevitable results still happen.

HIIT is explained to have the advantage of the extended prolonged oxidative effect such that your metabolism is stimulated and increased for a longer duration (2-3 days) spanning beyond only the period in which the exercise occurs. Essentially burst of high-output followed by lower intensity periods, this technique is great to mix it up in your routine. My only concern is that such intensity is hard on the body. Every year people die running marathons: should 60+ year old people REALLY be going balls-to-the-wall for repeated periods chasing after what they think is the only way to break a plateau or make some progress? :azzangel:

I'm not going to suggest that it's wrong...but I will offer an alternative that works for me. I get on my bike and go for rides that often run over 3+ hours. After 20+ minutes the blood-sugar starts to drop and the body starts burning fat, I've read that After an hour the fat-burning goes up 7x...so after an hour I imagine I'm in the "golden zone"....

Is this true? My "guy" (nutrionist/trainer/dietician...published writer, lecturer, etc) says there's a LOT of propaganda and bunk research and theories out there...so who konws, it's just a matter of what you read, what info you've been exposed to and what you select to believe.

Common theory suggest that intense exertion can not be fueled by fat...fat burns too slow and can only be metabolized at a certain rate. When the body is putting-out it's mostly burning glycogen in an aerobic state. Heavy-duty intense exertion involves ATP/Creatine-Phosphate and is anarobic, which is why lactic acid builds/accumulates. While many people imagine a "fuel-select" switch...it's just not accurate: your body burns a mixture of all fuels...but the fat IS the long-term reserve that many of us have trouble tapping into. Indeed, I imagined much of my exercise was just depleting my glycogen and then replenishing it again when I ate: why won't this fat get off my body????

For me, the long-haul extended rides REALLY made the difference. I think the low-impact nature of biking is good...but who am I kidding: I dial in some HIIT every time I come towards the top of the hill and churn-out a burst of energy till I reach the top. LOL, I'm so wiped-out when I reach the top of the hill that a 6 year-old could knock me off my bike and steal it and I'd just be sitting there limp & panting :)

Well...to actually conclude...we can theorize different approaches and discuss the many merits of each...but in the end my experience has strongly dictated:

1) Watch the diet more then anything, you'd be shocked how many more calories you eat then you imagine. I've found it's diet more then anything...and remember: the body isn't stupid, it knows you just blew 2,000 calories on that long ride and it WILL hormonally command, inspire and demand of you to replenish what you lost. It doesn't know you're trying to lose weight...your gonna get the hungry signal until the blood-sugar is up.

2) Exercise is exercise...just move more and don't obsess with all the different techniques and approaches. That's not to say there's no merit or advantage of one over the other...but in the end, it's ALL good.

And one other thing: don't go nuts over that scale!!!!

Over the course of some 4 weeks I rode my bike, swam miles, played racquetball and ate very little, I did my own hardcore/extreme World's Biggest Loswer....I expected a big drop big-time on the scale...instead (to my utter dismay) I had gained 2.5 pounds. I was devasted and psychologically crippled....UNTIL the body-fat calipers were applied. I mean, I know I felt leaner and looked leaner...but the scale went up...so wtf? To our astonishment, I had dropped 2.4% in body-fat. Muscle does weigh more then fat and that's not like the bogust excuse tubby woman use with their thyroid & "water retention"....it's real.

Watching your body lose fat is like trying to watch your hair grow: you just can't see it. I lost over 40 pounds and still look in the mirror wondering when it's finally going to come off....then I saw some pics of myself and it came clear. If you're doing it right, the scale may not drop much and you may not see/feel the progress.....it's a slow process, but if you stay the course and do the right thing....progress is inevitable.

Sorry for the long post, I perspire to inspire! ;)
 
Congrats!!!

My trainer has me doing HIIT too, and my body is taking on a whole different shape as well, after 4 weeks!!! Sometimes when I look in the mirror I just can't believe it's me.

Most HIIT is only 20 - 30 minutes in duration.

As far as being " hard on the body " , it'd bet it's no worse on your body than long distance ' endurance ' running or weight training.

Every year people die running marathons: should 60+ year old people REALLY be going balls-to-the-wall for repeated periods chasing after what they think is the only way to break a plateau or make some progress? :azzangel:

Perhaps - but it's rare.

And, I suspect it much less rare than those who die each year due to a sedentary and unhealthy lifestyle.:)

I'm not going to suggest that it's wrong...but I will offer an alternative that works for me. I get on my bike and go for rides that often run over 3+ hours.

That's fine if you have the time - but few people have the luxury to dedicate 3+ hours to cardio 3 /4 times a week .......as they can with things like HIIT and or weight training that may take up only 20 - 60 minutes per session.

After 20+ minutes the blood-sugar starts to drop and the body starts burning fat, I've read that After an hour the fat-burning goes up 7x...so after an hour I imagine I'm in the "golden zone"....Is this true?

If it's aerobic cardio, your body is burning fat to some degree for almost the entire first 20 minutes - not simply after 20 minutes.

The amount of fat burning that takes place is primarily a function of your intensity/ available oxygen...not simply the duration of exercise per say.


My "guy" (nutrionist/trainer/dietician...published writer, lecturer, etc) says there's a LOT of propaganda and bunk research and theories out there...so who konws, it's just a matter of what you read, what info you've been exposed to and what you select to believe.

Common theory suggest that intense exertion can not be fueled by fat...fat burns too slow and can only be metabolized at a certain rate. When the body is putting-out it's mostly burning glycogen in an aerobic state.

Actually, it's mostly burning glycogen in an ' an-aerobic ' state.

You have to have oxygen in order to burn fat - so in most cases, you're burning mostly fat and ( to a lesser degree ) glycogen in an ' aerobic ' ( i.e with oxygen ) state. So that's correct, intense exertion ( i.e you're winded and oxygen deprived ) can not be fueled - primarily - by fat.

That said, you can't do steady state cardio for 20 minutes without burning some fat for most of that time.

Heavy-duty intense exertion involves ATP/Creatine-Phosphate and is anarobic, which is why lactic acid builds/accumulates. While many people imagine a "fuel-select" switch...it's just not accurate: your body burns a mixture of all fuels...but the fat IS the long-term reserve that many of us have trouble tapping into.

Why ?

If you're training aerobically and have the oxygen needed to burn fat - why is it a problem tapping into fat ?

Indeed, I imagined much of my exercise was just depleting my glycogen and then replenishing it again when I ate: why won't this fat get off my body????

Perhaps it was your diet.

For me, the long-haul extended rides REALLY made the difference. I think the low-impact nature of biking is good...but who am I kidding: I dial in some HIIT every time I come towards the top of the hill and churn-out a burst of energy till I reach the top. LOL, I'm so wiped-out when I reach the top of the hill that a 6 year-old could knock me off my bike and steal it and I'd just be sitting there limp & panting :)

Thing is, HIIT burns more fat ' overall ' for a given level of calorie expenditure than steady state cardio does - making it the more efficient way to lose fat.

Good to hear ...if you want shred fat ...HIIT ( along with a good diet of course ) is the way to go IMO !:)
 
Wrangell certainly made some excellent points!!!

To be forthright, I'm an insulation contractor and that's why I mostly know. As far as my knowledge of fitness & exercise, the extent of my thoughts have been formed from listening, reading and hearing what other experts say. Much of it is like a radio bandwidth: while you'd think everything should be consistent, it seems like different theories support different notions and methods are evolving on a constant basis....it just depends which information you tune into.

It has been explained to me repeatedly that there are 3 basic forms of energy that the body burns:

FAT
GLYCOGEN
ATP/CREATINE-PHOSPHATE

Fat & Glycogen are aerobic (requiring oxygen) while ATP/Creatine-Phosphate is anaerobic. Perhaps I didn't express this clearly in my previous post.

HIIT is HIGH INTENSITY....my trainers made me go to my absolute balls-to-the-walls hardest for about 5 minutes, then a period of moderate, then back to High intensity. It hurts, it's depleting and it's tough, VERY tough. If I was biking, they'd be yelling at me to run/bike as if a mountain lion was on my tail. No doubt, my heart-rate was 175-185 when I came off the high-intensity interval. I'm 42. I can't imagine a 65 year-old doing that....it just seems more practical to keep a moderate pace for a longer period then push that hard/intense.

And btw...unfortunately, I've read of several participants having heart-attacks while doing marathons. When there is a large-city marathon, it's very typical for a few people to need to be taken to the hospital and occassionally die. I wish it were "rare", but it's more frequent then we wish to acknowledge. Seemingly fit people crap-out all the time. At my local gym, we've had about 4 members over the past 3 years abruptly die. Some were in their 40's. Honestly, it's hard to talk/think about....I'd rather not. Sure, they (hopefully) had unknown issues or heart defects (like John Ritter)...but still, it's something to consider. I'm sitting here thinking that perhaps the trainers that had me doing HIIT were advocating a more intense version then what we are discussing here.

The other thing I'm told is that the actualy fat being burned while doing HIIT is not the key factor, HIIT is particularly effective for it's ability to affect your bodies continued fat oxidation post workout. With low-intensity your body burns fat as yo do the exercise, when you stop...your body resumes it's previous rate....BUT with HIIT, your body continues burning fat with an accelerated metabolism long after and continuing past the point where you stop exercising...so it's the post-workout benefits that make HIIT so effective. I'm NOT advocating that HIIT doesn't work, just concerned about it's potential for 60+ year old's to perform. From the heart-rate reported from the forum member (what was it, 130?)...that doesn't seem dangerous at all.

I entirely agree with you....dollar per value, or time-per-sweat, HIIT is the most efficient/effective way to get the most bang for your...uh, bang? :)

In the end, I'll still think it's best to mix it up...but I think we're on the same page here and I do appreciate your clarifcations!
 
Wrangell certainly made some excellent points!!!

It has been explained to me repeatedly that there are 3 basic forms of energy that the body burns:

FAT
GLYCOGEN
ATP/CREATINE-PHOSPHATE

Not exactly...there's one basic form of ' energy ' and 3 basic systems that deliver it.

The basic form of energy your muscles ' burn ' in order to contract is something called ATP ( adenosine triphosphate ) - fat, carbs, glycogen & protein simply participate in the production of ATP thru various ( 3 ) basic energy systems. Namely the;


Aerobic System :

- requires oxygen and burns BOTH fat and sugars to create a lot of ATP at a slow rate​


Anaerobic / Lactate System :

- doesn't require / involve oxygen ( i.e therefore can't burn fat ), burns primarily ' sugars only ' to create relatively less ATP but at a relatively faster rate​


Creatine Phosphate System :

- doesn't require / involve oxygen, fat or sugars and burns both existing ATP stores in your muscles as well as what it burns by creating a relatively small amount of ATP very quickly​


Fat & Glycogen are aerobic (requiring oxygen) while ATP/Creatine-Phosphate is anaerobic. Perhaps I didn't express this clearly in my previous post

Not quite.

Glycogen doesn't ' require ' oxygen.........that why it is the primary fuel used during anaerobic exercise ( i.e NOT requiring oxygen )

HIIT is HIGH INTENSITY....my trainers made me go to my absolute balls-to-the-walls hardest for about 5 minutes, then a period of moderate, then back to High intensity. It hurts, it's depleting and it's tough, VERY tough.

Correct, they are putting an emphasis on training your Anaerobic / Lactate System.

The other thing I'm told is that the actualy fat being burned while doing HIIT is not the key factor, HIIT is particularly effective for it's ability to affect your bodies continued fat oxidation post workout.

Correct.

thanks for your input guys. in a nutshell 4 weeks of hiit has made more of a difference in my fat levels than 3 months of steady jogging. i'm 26 with a full time job, a dog, a cat a 3yr old girl, a goldfish, and my girlfriend to look after so 3+hours of cardio is wheeey out of the question for me
 
2 out of 4 ain't too shabby ;) Thanks for the info. I was wondering if Glycogen was aerobic or anaerobic, thanks for the clarification!

Ed....I totally hear ya: goldfish can be tough!!! :) Glad the HIIT has made such an impact for ya!

Wrangell...I would like to tap into your excellent knowledge & understanding of how the body creates energy. Your explanation was excellent, I've never quite heard it all put together that well...I think I'll quote your info from now on, thanks!

What I'd like to know/ask is for an explanation of this whole concept of catabolism (sp?). I had a trainer (who I did not train with) tell me that when I work-out with weights I'm tearing-down muscle fiber, and then when I follow-up with cardio I'm then eating-up that torn-down muscle! He made it sound like it was an unproductive circle. I really doubt he's accurate, but it does bring to light the concern over this whole notion of the body turning to it's own muscle as a means of generating energy. My goal is to burn, burn, burn fat...I want it off my body (well, you know...reduced so I look better)...I don't want to lose muscle in the process of my doing cardio.

So let me say this....we all know the concept of "spot-reduction" is bunk...you can't do an excercise and expect it to burn fat in one particular focused area (ie, sit-ups burn belly fat). Perhaps I shouldn't be so certain with my saying it's bunk, but everything I've read, heard and been told tells me spot-reduction is nonsense. SO...in light of such a notion, is there such thing as excercise that focuses more on burning fat rather then glycogen or other stuff?

Can a person get rep-power for asking good questions, or just answering/helping people? ;)
 
3+hours of cardio is wheeey out of the question for me

Well......what I do is call-forward my business calls to my cell phone and then I take the phone with me as I bike. I usually get names & ph#'s and call customers back once I return to the office, but I fully admit I'm very fortunate to have this ability to wheez 3-hours 2x during the week to ride.

Now if they could just invent a cell phone that could work for me while I'm swimming! ;)

theres such a thing! when i was in the surf once i saw a surfer answer a phone :eek:

Oh yeah...they probably have waterproof phone cases and that would work fine for surfers, etc. But I'm swimming laps in the pool and there's just no way I could have the phone with me in a manner that I could hear it, let alone radio-waves get through the water!

Also, I love wearing my ipod when I swim....it fits right into a nice waterproof case and the earphones nicely fit in the ears. Once you get them adjusted right and use the strap from the goggles...it works great and really lets me go for long distances without the boredom!

I totally agree! I'm lucky to be at a gym where the personal trainers actually know what they're doing. It makes me feel like I get what I pay for. :cool:

You can say that again. I saw one of the trainers working out late the other day and he was swinging very heavy weights in the wrong manner as in an expert village video. Coming to think of it I've seen a guy who should know better doing a pro-wrestling type round-house rather than a proper martial arts kick so its easy to pick up bad habits.
 
tried jogging,running,srintng HIIT on the running machine after work today for the first time. usually i run on the grass. I gave in after 23 mins 22 secs it totally fooked me, at some points my heart rate was through the roof but with half the impact on my knees downwards. Only thing is i had to get used to running on the bloody thing again, i'm 6ft5 and trying to balance on it at was a nightmare. flat out i held on to the bar for support otherwise i would have fallen over like hasselhoff after a few pints. well 4 hours on and my heart rate is still up, was going to go out tonight but i need some rest after this weeks training (wimp) the running on the machine seemed to cane me more than the ground, i can only put it down to the fact that on the machine you are forced to stay at the same pace where as oon the ground you can slow slightly without realising? correct me if i'm wrong..
