HIIT advice. How long at high intensity?

Hi all. Apologies if this has already been answered but the search will take days.
Question: In a 30 minute elliptical workout (for example), how much of the time should one be at high intensity? Right now I'm doing on average about 8 min at high intensity (approx 180bpm) and the rest mostly low intensity. Is 8 minutes enough? And I don't want to exceed 30 minutes in total. Thanks!

That doesn't actually sound like you're doing HIIT at all. If you can perform an activity for 8 minutes straight, I think it's safe to say that it is being done at a relatively low intensity. For HIIT, you want to remain (mostly) in anaerobic metabolic systems while exerting yourself. It would actually be pretty hard to achieve that on an elliptical. If you don't want to do weighted variations for HIIT, I would recommend doing it on a treadmill with an incline instead.
That being said, the most common starting place for people is 20 seconds of high intensity exercise followed by 1 min of low intensity exercise for 20-25 minutes. This could be changed up however you feel is necessary, though. I have found that it is better to progress by shortening the rest periods than it is by extending the periods of work but other people would differ from this opinion.
You could also look up the Tabata protocol which is usually done with a weighted exercise (I like front squats and heavy keg slams) but it could be done with pretty much anything.0 -
I should have been clearer. I'm doing a 3 min warm up, then alternating 30s high intensity with 60s low intensity, then a 3 min warm down. Sorry.0

And thank you. I think I'm relatively close to your suggestion.

30 secs to 1min is a good place to start. How are you finding the minute in terms of ability to recover?0

That's not what is typically called high intensity. High intensity can't be maintained for more than about 20 seconds, because you're supposed to be going way over your 100% V02max limit. And you'll typically need more than 60s to recover from it, otherwise it'll be difficult to get back over 100%, but that is dependent on fitness level so you'll have to experiment.
This is also very taxing on the body - to get full benefits and minimize the risk of injury, a proper cardio base should be in place first.
But the first question to answer is....what, specifically are you trying to accomplish?0 -
I do circuits of 20 seconds high intensity 40 seconds medium recovery for 5 minutes and then 1 minute low intensity full recovery for half an hour with a 5 minute gradual warm up and then 10 minute gradual cool down.0

Theres a couple here to give you an idea.

I am trying to lose fat and minimize the time I work out. My normal cardio routine would be about 6 mile run at around an 8:30 pace. My base is fine. The high intensity portion of my HIIT workout, I get to about 175-185 bpm. The maximum heart rate I've ever recorded with a chest strap is 202 bpm.

Thank you. It took me four time reading this to do the math! Haha. But I get it. I like it.0 -

HIIT done properly burns very few calories, because it still comes down to distance covered, which is very low relative to steady state. Usain Bolt's 220-odd pounds is burning single-digit calories while running a world record 100m.
HIIT is a very useful training tool and generates certain physiological benefits (while missing out on others, like any other exercise), but if the goal is to maximize calorie burn, steady state running for longer periods of time is where it's at.
The fact that HIIT jacks your heart rate is meaningless for calorie burns.0 -

Calorie burn doesn't necessarily correlate with fat lost.0 -

I thought there was a beneficial thermic effect that lasts for sometime afterwards? Also, I play a lot of tennis and I don't think long steady runs are great for explosiveness.0 -

You mention in previous comments that you also steady state run as well I believe. HIIT is great to incorporate into any long term fitness plan but I wouldn't say its the best way to burn off fat specifically at least not compared to steady state distance running or similar.
It seem though like you already have that in your routine as well as rec sports, which I totally agree that HIIT is great for benefiting other quick paced explosive sports like Tennis.

There are many interval patterns. The original was Tabata at 2/1 High/Low, which is oo much for me.
Whatever works for your current level of fitness and desires. Right now I can do 20 seconds on, 90 seconds because I've been slacking over this stupidly cold winter. I was up to 30 seconds on, 40 seconds off, repeat 5 times.
Personal preference, my minimum cadence is 80 rpm at the low end because when I get out on the real bike, I prefer to gear down and spin rather than mash.
Intervals I think will help with anaerobic capacity and VO2max. For explosiveness I think you might want to look into plyometrics.0 -

Thank you. (Yes, awful winter is right. Too cold to walk two blocks to the gym #solazy)

The human body can't oxidize stored fat quickly enough to support high intensity activities. The amount of fat used for any given activity maxes out once intensity has reached moderate levels - you can push harder, but you won't be able to burn fat any quicker, energy will be found from other sources (or you'll crash).

They are, as part of an overall program. Being able to run a moderate 10k produces physiological changes that interval training can then leverage to increase explosiveness.
Other than at the extremes, both intervals and steady state are needed to optimize physical performance. The ratio of the two will depend on what physical activity the exerciser is trying to optimize for.0 -

Evidence based exercise - clinical benefits of high intensity interval training
So there's your answer about how long to make the exercise & rest periods.Aerobic exercise has numerous benefits for high-risk populations and such benefits, especially weight loss, are amplified with HIIT. High intensity interval training involves repeatedly exercising at a high intensity for 30 seconds to several minutes, separated by 1-5 minutes of recovery (either no or low intensity exercise).

EPOC Comparison Between Isocaloric Bouts of Steady-State Aerobic, Intermittent Aerobic, and Resistance TrainingExcess postexercise oxygen consumption (EPOC) is dependent on intensity, duration, and mode of exercise. The purpose of this study was to compare the effect of both exercise mode and intensity on EPOC while controlling for caloric expenditure and duration ... Both [weightlifting] and [HIIT] aerobic work increased EPOC to a greater degree than did SS work, indicating that either mode may be more effective at increasing total daily caloric expenditure than SS aerobic exercise.

Running sprint interval training induces fat loss in womenFifteen recreationally active women ... completed 6 weeks of running [sprint interval training] (4 to 6, 30-second "all-out" sprints on a self-propelled treadmill separated by 4 min of rest performed 3 times per week). Training decreased body fat mass by 8.0% ... waist circumference by 3.5% ... it increased fat-free mass by 1.3% ... maximal oxygen consumption by 8.7% ... and peak running speed by 4.8% ... Running [sprint interval training] is a time-efficient strategy for decreasing body fat while increasing aerobic capacity, peak running speed, and fat-free mass in healthy young women.

Thanks for this. I have no idea how to cardio.0

I also use the elliptical for HIIT I warm up for 3 mins then increase the resistance to max and push hard for as long as takes to get me to 170 bpm then back down again until 150 bpm I continue with this for 20 minutes.0

Some will say it's not true HIIT if you aren't going all-out for the "high" portion. Personally, when I say high/low I mean there's a large degree of intensity separating the two extremes. I may not be running as fast as I possibly can for my high, but if I run at 6mpm (minutes per mile) compared to walk at 30mpm, that's a large separation in my book (numbers chosen for example purposes only).
That said, on a day I'm feeling strong I'll go at a 1m:1m ratio of high/low, on a day I'm feeling off I'll go at a 30s:1m ratio. Not a world-class athlete, never will be, but it works for me and is a fun different day from steady-state running.0 -

The physiological differences between going truly "all out" or not are substantial. The whole point is to force your muscles into an anaerobic state, and if that doesn't happen, it's basically just normal running (or cycling or etc).
I tell you what - lets do this in the right order. Since the article was the first thing posted, how about explaining what the article actually gets right.
After all, just posting a random link from the internet doesn't make it so.

Not really. I provided a few examples of Hiit workouts to give the OP an idea of what they can look like for an eliptical. According to you its all wrong, but you wont tell us why.
Presumably you are more qualified or experienced than the person who wrote the article?0 -

The EPOC from HIIT I've seen estimated at 14%.
And 14% of a small number (as HIIT is short duration) is very small indeed - irrelevant in fact.0
