I have been following this system for a few months now, only 15 mins three times a week. Not sure how much calories this burns but would like to add it to my diary, any advice?

    Describe what you actually do in this 15 minute workout but with such a short duration it's not going to be very significant in term of calories.

    If this is your only exercise for the week, no matter the intensity, I highly doubt is enough to make any difference.

    I'd log it as 15 minutes walking, over the week it'll give you an extra 150 for your weekend.

    Should add not to listen to his sales pitch that 15 minutes will reset your metabolism and burn fat fast.

    It's rubbish to try and sell his work out plan.
    @RuNaRoUnDaFiEld
    Your comment made me do a little Googling as hadn't heard of this before....

    From the site:
    "But only certain forms of exercise have been scientifically proven to force your body to change, adapt and turn on your fat-burning potential."

    What a load of cobblers! My woo meter just went all the way to eleven.

    Well TRUE HIIT does increase EPOC, I'd argue a great many people doing interval training aren't doing true HIIT.
    As far as resetting metabolism or whatever, yeah that's kinda nonsense.

    I think that claim is the classic example of someone "running with it" without actually knowing what they're talking about.
    20-30 minutes of HIIT is MORE effective than the same amount of steady state cardio (and by a somewhat significant amount too from what I understand), it's not some magic thing.

    If you can sustain the intensity for 30 minutes you're not doing HIIT.

    Any exercise that breaks down muscle tissue will produce EPOC.

    HIIT can't be more or less effective, only better or worse for a specific goal. And the exercise world isn't intervals and steady state only, it's a gradient. Actual steady state cardiovascular exercise is pretty rare.

    And, in order to see clear contrasts, most "HIIT vs steady state" studies set the steady state intensity at 50%-60%.

    If you're actually doing true high intensity intervals, 15 minutes is a lot, and burns more calories than most folks on this thread seem to think. The primary benefit of HIIT is that it does a lot in a little time. I log my HIIT cycling at 200 cal / 15 minutes, and my weight loss has consistently been higher than predicted - down 96 lbs currently. Sometimes I get sick of doing HIIT and do other cardio instead, and my rate of loss slows. It does work. Just FYI in case any diabetics are reading this, it's also the most effective way I've found of quickly lowering blood glucose levels. Doesn't work for everyone, for some diabetics the stress hormones from high intensity exercise actually raise levels, but for me I can reliably drop my levels from 150 to the high 70s in 15 minutes. The main problem with HIIT is that it's only HIIT if it's high intensity FOR YOU - which means that you must keep upping your intensity as you become better conditioned.

    You say you've been doing this for several months - you should have some idea by now of how fast you are losing weight, which should give you a rough idea of how many calories you are burning in a day. Figure out how many you should be burning at your base activity level, factor in your food, and see if there's anything left over.

    How are you coming by those calorie estimates?
    What are your intervals?
    What's your FTP?

    Well, I started from the estimates given by MFP for stationary bike, and averaged them with the actual calorie burn recorded on my bike. MFP has stationary bike, vigorous, 10 minutes at 140, very vigorous for 5 minutes at 84. I've been ramping the difficulty over time as I got used to it. Currently doing 5 repeats of two minutes at 22 mph on a moderate hill setting with 1 minute at 27 on a higher hill setting. Can't recall what rpm that is but it's something like 92 and 111. My bike generally gives me about 300 cal for a 15 minute session. I do eat back my exercise calories, and I continue to lose weight at or above predicted.

    Actual HIIT is no joke. If you are not soaked in sweat and unable to talk after 15 minutes, it's not HIIT. It is definitely not the easy way out or a shortcut.

    It's not my estimate, but the bike's estimate, and MFP's estimate.
    Hope you realise that's two very unreliable sources.

    Glad it's working for you though.

    I guess my experience doesn't exist, then. I'm OK with living an imaginary life, then.

    The short, 15-minute HIIT workouts (or maybe the nay-sayers would be happier if I called it "baby HIIT") were indeed intense for me, but perhaps it wasn't as "horrible" as it should have been since it was modified. Percent intensity is percent intensity, one might argue. My 90% then was a far cry from my 90% now (especially considering I was having trouble with daily tasks by the point where I began), and I'm sure my 90% now won't compare to where I end up. Either way, I suppose it doesn't matter as much now, since I've graduated on to other longer-period forms of improving myself for now. I did enjoy the workouts enough that I'll definitely be looking into the "grown up" version of HIIT (since there's apparently a difference) once I'm stronger.

    Kinda funny that some people think it's a disaster or inappropriate for someone like me (or at least where I started out) to do one of these workouts, seeing as it was recommended by one of my doctors. Then again, perhaps that's why it's "Baby HIIT." Even still, there must be something to gain even at that level, if they recommend it.

    I'm not sure what you are referring to by "baby HIIT". When you say your "90%", are you talking about performing to 90% of max HR? Were you doing something less that full, all out, HIIT? If so, it may not really have been HIIT. (They seem to call everything HIIT these days) It may have been Interval Training but not High Intensity. Might have been Medium Intensity even though it felt like high to you. Still very useful and effective. And much better than sitting on the couch by a long shot!

    As an example, I am very fit despite my age, 66. I weight train and I do various cardio, walking, running, intervals. I have done HIIT in the past. Warm up, through 15 minutes of work sets, through cool down it takes about 25 minutes. The work sets, either bike or sprints, are ALL OUT for 20 to 30 seconds. Then rest for 1.5 to 2 minutes. Then go again. By the 4th or 5th one, I feel like I might puke, my legs are burning, my lungs are burning and I'm wondering if I will pass out. That is High IntensityInterval Training. It is done at above 100% max HR.

    The difference may be accurate terminology. What your doctor recommended may have been Interval Training and he called it HIIT. Heck, at Gym's these days they say they do 1 hour HIIT classes. If you can do it for an hour, it ain't HIIT.

    If it was HIIT for you, it was HIIT for you, even if it wouldn't be for a more fit person. HIIT scales.

    By the way, you know what doesn't do a lot for weight loss? Steady state cardio.

    There are certain aspects of science which people on these forums just can't deal with. This is one of them. I'm fine with all the cardio slaves marking my posts woo, while I keep losing weight, my blood pressure is perfect now, and my resting heart rate is lower and lower. Whatever. If you feel validated by spending hours of torture to get the same results, have at it.

    Lmao someone's defensive

    I wouldn't say that. I have lots of older clients that cannot do HIIT of any sort due to joint issues and heart issues and steady state works fine as a way to help with calorie deficit.

    Well actually, the science doesn't support your statement. In the link I posted earlier Schoenfeld covers the actual science of the. Sounds like you would benefit from watching it. It's 50 minutes total but, IIRC, he details the fat burning of the various types of cardio at around the 20 minute mark.
