    IF, you could do HIIT for 30 minutes. Most can't, including me, and it's really recommended one doesn't. A typical program is 5 minute warm up, 5 intervals covering about 15 minutes, 5 minute cool down. If I did HIIT for 30 minutes, I'm sure I would be dead.
    I always get a laugh out of it when people say something like they jogged to the park, did their 30-minute HIIT workout, then jogged back home. If what you did was actually HIIT, you wouldn't have been jogging back home afterward. :D

    Right now my one and only concern is losing fat. Once I get to a healthy weight I will shift focus to increasing my athletic abilities once again. But until then, fat loss, and muscle maintenance as a result, is the only consideration.

    yeah, I would still rather walk for 2 hours than do that.

    Me too. Gasping for air and feeling like I'm about to fall over because my legs feel like jelly does not an enjoyable workout make, for me.

    Opposite for me. Not being able to walk or lift my arms after a workout makes me feel like I've accomplished something. Sort of a twisted inspirational boost.

    My logic is a bit twisted, but being able to eat 600-800 calories more after a 60-90 minute easy pace run makes me feel like I accomplished something. I wouldn't be able to burn even 20% of that with HIIT.

    I mostly just lift. Every set to failure. Running hurts my feet and gives me flashbacks to my childhood, being the fat kid and running 2 miles every morning to try to lose weight. Didn't work. My parents owned an Italian restaurant...

    Intensity will of course be different per an individual's fitness level. But the premise remains, it should be intense FOR YOU. Athlete or beginner, you should be spent within 15 minutes.

    I get you. The reason I would do it to improve my LISS is that it would increase my VO2 max and I can run for longer and at a better pace. This, for me, is more efficient for calorie burns and thus fat loss. Eg. I burn around 8 to 9 cals per minute walking up and down the hills where I walk. I burn around 14 to 15 cals per minute running.

    One of the issues I have with my weekly schedule and routine is what to leave out for the 3 weeks or so when I would include HIIT. HIIT has a similar impact to the central nervous system as weight lifting. Lyle McDonald talks, in the series referenced above about training overload and the impact on leg training in particular. So, if HIIT is included, something else needs to be scaled back (if one has a full 3x per week program working legs 2x) to avoid overtraining symptoms and adrenal fatigue.

    jdlobb, I know I quoted you and my some of my response is to you but a lot is really just a sharing of info. As I understand your situation, you are fairly recent to calorie restriction and training? If so, HIIT would not even be appropriate for someone in your situation until you had built a base of both cardio and muscular fitness.

    There are HIIT workouts that last longer, but those have longer rest periods. Like 1 minute all out followed by 3 - 4 minutes easy pace for say 10 rounds...

    Stef, I can't imagine why any length beyond 20 minutes would be referenced. I've done 20 minute recumbent bike sets. The inclined hill sprints I've done, I'm dying after 15 mintues. And I'm very fit.

    In everything I've read from people like McDonald and Shoenfeld, they reference 15 to 20 minute work sets with warm up before and after. I've never seen longer.

    I used to run stairs for about 30 min. on my lunch at work. I would consider this HIIT. 100% effort took 45sec. to get to the top and a 90 sec walk down. By the end of the 30 min. My 45 sec. Interval was nowhere near the top and I was practically crawling but I was still pushing 100% and breathing way harder than when I started. I felt like the mom going up the stairs in What's Eating Gilbert Grape.

    I was surprised myself as any HIIT I've done (and yes it really was HIIT) was 15mins...

    but it does make sense once you read about the longer rest periods.

    I remember my first HIIT...when it was done I laid on the floor and almost cried I was so spent.

    hate them btw...very rarely do them.

    My understanding is that as you get fitter, the rest periods should get shorter. Unless though you are training a specific protocol. Wingate sprints come to mind...

    Whenever I've done 20 minute HIIT sessions, the last 5-8 minutes are just me struggling to stay upright while floundering around with essentially nothing left to give. Afterward, I barely have the energy to drive home.

    Cardio is a waste of time (unless you actually enjoy it).

    Or enjoy the stronger heart and more plentiful food.

    I'll stick with my strong heart and plentiful food from weightlifting and HIIT. More bang for the buck.

    Not in my experience. Can't sustain HIIT long enough to burn any meaningful amount of calories, and whatever I burn I eat back twofold or more because it increases my hunger substantially. Now don't get me wrong, no one has to do cardio (or weight lifting, or HIIT for that matter), but you can't call any form of exercise a waste of time because there are clear benefits to being active, health and otherwise.

    Yes, sitting on your *kitten* is a much greater waste of time.
    Since I don't like exercising in general, I'm going to spend the least amount of time possible to get the greatest benefit which means high intensity. I just want to get it over with so I can get back to thing I enjoy.

    And that's totally alright! It's just, this sounds more like preference than opinion.

    Nah, I still am not a fan of cardio(but it's better than nothing). I believe there are much greater benefits from high intensity exercise.
    How do you know you don't burn as much calories doing HIIT? I believe that much shorter, high intensity exercise may not burn as much at the time, but the residual calorie burn from greater muscle stimulation lasts much longer resulting in more CO.

    EPOC (Excess Post Exercise Oxygen Consunption) for HIIT is 14%, for Low Impact Steady State it's 7%. That's the % of residual burn of calories burned during. FWIW. HIIT can't be done for very long so the overall burn is not that big. If you could do 30 minutes of HIIT, your Butner with EPOCH would be about the same as 60 minutes of LISS but who can do 30 minutes of HIIT??

    This would depend on the intensity of the HIIT. And as @GottaBurnEmAll stated not all "HIIT" is equal. To me, HIIT means the intervals are 100% all out.

    That is the HIIT I'm talking about and in exercise physiology circle based on studies, that is the commonly accepted number. This was discussed in detail on the Lyle McDonald article sjomial linked to. It is also the number Dr. Brad Shoenfeld uses. It pretty objective and not really the subject of much speculation as to variance.

    Less that 100% all out would not technically be HIIT but would be considered interval training. The EPOC would fall somewhere between LISS and HIIT depending on intensity. All HIIT is not equal because the Marketing woo machines call everything HIIT today. Things like 1 hours HIIT classes. If you can do it for 1 hour, it ain't HIIT!!

    PS: The link sjomial gave is the 2nd in a series of in depth article about the subject and references a lot of the current research. If that is the link you are kind of dismissive of in one of your posts above, I suggest you didn't read it thoroughly. There are links to both the initial article in the series and the following ones at the bottom of the one posted.

    I did read it, but I'll look at the references too. My main leaning to HIIT over cardio is that it is closer to weightlifting in it's muscle building potential... if I am not mistaken. However, I pretty much just lift and try to stay away from all that gross running stuff...

    That is the HIIT I'm talking about and in exercise physiology circle based on studies, that is the commonly accepted number. This was discussed in detail on the Lyle McDonald article sjomial linked to. It is also the number Dr. Brad Shoenfeld uses. It pretty objective and not really the subject of much speculation as to variance.

    Less that 100% all out would not technically be HIIT but would be considered interval training. The EPOC would fall somewhere between LISS and HIIT depending on intensity. All HIIT is not equal because the Marketing woo machines call everything HIIT today. Things like 1 hours HIIT classes. If you can do it for 1 hour, it ain't HIIT!!

    PS: The link sjomial gave is the 2nd in a series of in depth article about the subject and references a lot of the current research. If that is the link you are kind of dismissive of in one of your posts above, I suggest you didn't read it thoroughly. There are links to both the initial article in the series and the following ones at the bottom of the one posted.

    I did read it, but I'll look at the references too. My main leaning to HIIT over cardio is that it is closer to weightlifting in it's muscle building potential... if I am not mistaken. However, I pretty much just lift and try to stay away from all that gross running stuff...

    HIIT is always cardio. Cardio is not always HIIT...
