The Ultimate Guide To HIIT

HIIT workout routine

Alright, I can’t stand it anymore.

My mind is about to fucking explode.

I’m so sick and tired of seeing these incredibly overweight people slave away on the treadmill day after day in hopes of losing weight.

It’s a god damn epidemic and it needs to end now!

But if people continuously insist on working the treadmill, they might as well start doing something that actually gets them results. And yes, I’m talking about HIIT.

This article will be your ultimate guide to HIIT – what it is and how you can start using it to build your dream body in less time than ever.

An overview of HIIT

What is HIIT?

And no, despite what everyone thinks, HIIT doesn’t stand for  Herpes, Is It Tight?

HIIT stand for High Intensity Interval Training and it’s basically a form of exercise that alternates periods of high intensity exercise such as sprinting with less intense periods of exercise such as walking.

So for example, a HIIT workout routine might have you doing 30 seconds of sprinting, followed by 90 seconds of rest.

Pretty simple, right?

How long do HIIT workouts last?

Due to the extremely intense nature of HIIT workouts, they typically never last for more than 20 minutes. An effective HIIT workout can actually be done in about 10-12 minutes if you structure it correctly.

Do I need a treadmill to do HIIT?

No, it’s possible to do HIIT on any cardio machine such as an elliptical, stair master, bike, or rowing machine but HIIT tends to be most effective on the treadmill. You can even do HIIT outside without any equipment if you want.

How often can I do a HIIT workout?

I typically recommend people to do HIIT right after their weight lifting session. I’m not a huge fan of doing HIIT on non-weight lifting days since I like to keep those days 100% rest days.

How often can I do HIIT?

Limit your HIIT workouts to no more than 3x per week. Don’t try to do more, especially if you’re doing heavy lifting since this will more than likely lead to overtraining.

Do I need to do HIIT to lose fat?

No, HIIT or any type of cardio is definitely not necessary to lose fat. When trying to lose fat, the most important thing to do is to create a calorie deficit and perform some sort of resistance training to preserve muscle mass.

Benefits of HIIT

Well, let’s see:

  • You no longer have to slave away on the treadmill for 60 minutes at a time.
  • Because HIIT is an anaerobic activity like weight lifting, it will actually help you preserve muscle mass.
  • You boost HGH levels, which help you burn fat and preserve muscle.
  • It mimics real life situations where you actually perform short intense bursts of activity. Because seriously, in what real life situation would you have to run 3 miles?
  • HIIT actually shapes and tones your lower body quite nicely. For those who have very bulky looking legs, HIIT can act as a nice substitute for direct leg exercises.

Disadvantages of HIIT

Like all good things in life, there are unfortunately some downsides to doing HIIT.

  • This is not a workout for lazy people. If you’re going to do HIIT, then you can’t half-ass it. If you’re told sprint for 30 seconds, then you better perform an all out sprint for 30 seconds (For help, imagine yourself being chased by a cheetah).
  • HIIT can definitely impair recovery. This is not a workout that you can do every day. If you do HIIT every day, then you could be looking into some serious overtraining problems.
  • Also, if you’re doing a super low calorie diet, I definitely don’t recommend HIIT.

My 2 favorite HIIT approaches

There are countless variation of HIIT, each with varying work to rest ratios.

Below, I have listed my 2 favorite HIIT approaches:

Approach #1 – 30 seconds work, 90 seconds rest

The first time I ever did HIIT, this was the approach I used. To do this workout, do the following:

  1. Get on a treadmill and perform a light warm-up by doing a fast walk/light walk for 3-5 minutes.
  2. Slightly increase the incline to about 1.5.
  3. Amp up the intensity on the treadmill so that you performing an ALL OUT sprint for 30 seconds.
  4. Decrease the intensity so that you’re back to a walking pace. Walk for 90 seconds.
  5. Repeat steps three and four 7-10 times.

Approach #2 – Stop and go method (15 seconds work, 10 seconds rest)

This is another approach with HIIT that I’ve been experitmenting with lately, and it’s quickly becoming my “go to” HIIT routine. This approach to interval training is a bit more unconventional but it’s definitely effective.

Also, this approach can only be done on a treadmill.

  1. Get on a treadmill and perform a light warm-up by doing a fast walk/light jog for 3-5 minutes.
  2. Slightly increase the incline to about 1.5.
  3. Jump to the sides of the treadmill (the parts that aren’t moving) and set the intensity to a point where you’ll be doing an ALL OUT SPRINT.
  4. Jump back onto the belt and sprint for 15 seconds. When jumping back on the belt, make sure you hold the railings at first. Remember, the treadmill is moving EXTREMELY fast, so hold the railings.
  5. Jump back to the sides and make sure you hold the railings. Rest for 10 seconds
  6. Repeat steps four and five for 10-12 minutes.

Make sure you’re progressing over time

HIIT is just like weight lifting – you need to continuously progress.

Doing the same workout day in and day out isn’t going to benefit you. Every time you do a HIIT workout, you need to try your best to progress forward.

This means increasing the speed, increasing the incline, increasing the total amount of sprints done, or decreasing the rest time. As long as each workout is slightly harder than the next, then you’re good to go.

Stop running, start HIIT-ing

Look, I’m not saying that traditional running is completely useless. It’s just not the magic pill that everyone makes it out to be.

I mean, there are situations where running is better than HIIT (e.g. training for a marathon), but most people do endless amounts of running in hopes of losing weight and in that case, running isn’t the best solution.

Feel free to ask me any questions you have on HIIT in the comments below and if you guys found this article helpful please consider “liking” an sharing it with your friends.

P.S. Rusty Moore just came out with a new cardio workout program called Visual Impact Cardio. I normally don’t like to push products too much on my site, but this is honestly the best complete cardio workout to help you lose weight right now. It combines both HIIT and low intensity cardio in strategic ways to help you get in the best shape of your life.

  1. Hi Keith,

    I do push pull/pull/legs-core on a 5 to 7 day cycle and was doing 3 to 5 miles on the treadmill on one of my off days and one day on after lifting so I got at least 1 and usually 2 or 3 total rest days each cycle. On Jan 27 I switched from slow steady cardio to HIIT which has helped fat loss and improved my cardiovascular fitness. I do 6×1 min sprints with 1 min easy running in between. Now it has been 9 weeks and have increased from 9.1mph at 2 degree incline to 10.2mph at a 4 degree incline and continue to increase the sprint speed, slow speed or incline almost every workout.

    My question is, how many more weeks should I keep increasing speed/incline before stepping back in speed or taking a complete HIIT break to consolidate gains. On one hand I am still making great gains and showing no signs of overtraining. On the other hand, when I compare to weight lifting, 9 weeks is already a fairly long meso cycle so maybe its soon time to step back?

    Thanks in advance for any advice.

    1. I’d say 6-8 weeks. I’ve done the whole push/pull/legs routine where I’m training 6 days per week. Shit is really rough to do long term, I personally wouldn’t recommend HIIT in addition to that but if it works for you, great.

      1. Thanks for the advice. Just to be clear, I don’t do Push/Pull/Legs twice in a week plus Hiit, but rather once and my cycle is between 5 and 7 days. So typically I would do 6 days 1. Push+Hiit 2.Pull 3.Hiit 4. Off 5. Legs 6. off. Though I may skip an off day or add an extra off day depending how recovery is going.

  2. Thanks for the info Keith.

    I have been looking for more information on HIIT and what other exercise should accompany it for weight-loss. I hear you saying that HIIT should only be done for no more than 3 days per week but what about the rest of the days? What would be the best routine for weight-loss mixed with a HIIT routine? or is HIIT 3x a week all you need?

  3. Hi Keith,

    I’m doing HIIT on my stationary bike. 6 Seconds full speed, 9 seconds rest & repeat it as much I can. It is a real killer, so I only last for 5-7 minutes. I’m “dead”.once I’m done. My question is why it is only recommended to do it 3 times per week ? Need to give time for the body to recover ? 🙂

    1. i don’t do the 6/9 second method you described so it doesn’t seem to bad. If you think you can handle more and you feel fine, go for it.

  4. Hey, I’m a 20 year old girl, 5 ft 6 inches and 143 lbs. I’m looking to lose around 20 lbs. But the thing is I don’t want to gain muscle mass and look bulky, is HIIT a good workout for me?

  5. Hi Keith,

    Your post is very informative, thank you.

    Do you think doing HIIT outside of the gym (bodyweight exercises) 3 days a week + 2 days of weight and light cardio training at the gym + 2 days of yoga or other light exercise would be effective? Combined with a good diet ofc.

    Do you recommend any supplements for women? I’ve been going to the gym regulary for almost a year now, mostly doing cardio, and I have not seen any results except for the improvement of my overall fitness ability. I figured I am doing something wrong, came across a study which mentioned the genes responsible for our reaction to aerobic exercises and it also touched on HIIT training hence my interest.

    Although my BMI is said to be within the ‘ideal’ range, I don’t think so. I’d definiately like to loose some fat and gain muscle.

    1. bodyweight exercises isn’t really HIIT.

      Supplements? Depends on your goals. You don’t really need any supplements unless something is lacking in your normal diet.

  6. Awesome article! Can I effectively do a HIIT with no running. Say my treadmill set at 3.0 speed for rest and for my “hard part” increase my incline to 10-15 then back down for my rest and so forth……please help!

    1. And to give you some extra info; I strength train 6 days a week and was doing cardio 4 days a week for 30-45 mins usually at a 3.0 with a 5°/• incline….

    1. No I wouldn’t, risk of injury especially on a treadmill is too high.

      I would start by losing a lot of weight via dieting first. You can do some low impact cardio like walking on an incline.

  7. I’ve actually been doing it on a stepmill and its been great but if u advise against it I will reassess.Kind of a bummer cuz I hate doing long cardio.Anyway great article

  8. Your logic is inconsistent and completely wrong.
    First, you said HIIT is not necessary to lose fat, but later, you said it boosts HGH levels, which help to burn fat.
    I’ve lost 20kg just by doing HIIT and not restricting my calories.
    Next time, do a thorough research and provide links to distinguished papers.

    1. how does that make my logic wrong?

      I said it’s not necessary to lose fat since you can lose fat via only diet. I said it helps you lose fat which doesn’t imply it’s necessary.

  9. Hi Keith

    I have a significant and permanent leg injury which prevents me from running or fast walking. I can do short bursts of burpees and squats.

    Could I do a HIIT workout geared around these exercises and some upper body exercises?

    Thanks.

  10. Hey Keith,
    I’m looking at losing some weight. I been going to the gym for a long time and just looking to lose a bit more weight. I’m 195, but I’m slim, big arms.

    I’m doing 3 sets of suicides in the AM. A set being 6 sprints back and forth.
    Then I’m doing a little bit of weight lifting after work then going on diff cardio machines and doing 30 seconds of intense difficulty as fast and as hard as I can, followed by 90 seconds of low intensity. I do this for 18 minutes. Does that sound okay? If I did that 3 days a week would it help?

    1. Your workout itself seems very intense and that’s fine. But in the end, it’s your diet which is going to dictate your fat loss.

  11. Good article. However very opiniated and quite foolish. Very overweight people start slow in the gym because the excess weight they carry makes it tough for them to run fast. Since they are very overweight they are most likely medically advised to take it slow too. HIIT would be very off putting and dangerous for an obese person. So stop being so vulgar and potty mouthed especially about things that don’t concern you.

    1. you’re right Sam. I didn’t write this with very overweight people in mind so I see your point. I will update the article. Thank you.

      But I will not stop being potty mouthed.

  12. Hey! Ok I’m 9 weeks from hitting the national stage in figure. I usually start around 8 weeks out doing 60 mins fasted incline walking on my treadmill and I’m wanting to switch it up bc I don’t find its really THAT helpful. I thinking of doing a few days a week sprinting on a track at night and doing 30 mins stepmill at the gym after lifting which will be 6 days a week. Do you think this will help to bring me in leaner and help cut my legs up better? I always thought sprints would keep my legs bulky?

    1. I don’t want to give you advice that could jeopardize your prep without knowing all other aspects of your training/diet…

      But I would probably do 2-3 HIIT sessions and do incline walking for 15-20 min afterwards. Of course this will help you lean out more since it burns more calories, assuming you don’t compensate with extra calories in your diet.

      I find direct leg movements like squats make legs much more “bulky” than sprints. Of course this depends of your definition of bulky as well.
