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. great post..except i dont have accesss to a treadmill!!! do u mind giving a sample hiit work out on an elliptical machine for a beginner who is 220 pounds…will be much appreciated!

    1. Hey gopi,
      You could do Approach #1 on an elliptical. But instead of sprinting you would just push as hard as possible on the elliptical for 30 seconds then go back to a much lower intensity for 90 seconds.

      1. i actually find that using the elliptical is easier to control and also you can set the resistance to a high level and push as hard as you can without fear of falling off! and it burns like hell too! this has worked for me over the past year and i dont use the treadmill anymore
        i do 30 on 60 off or 30 on 30 off for 10 cycles

        1. Hey wolverine,
          The treadmill is a good alternative. I use it when there are no treadmills available. Thanks for stopping by.

  2. Hey Keith, you are right about how annoying it is seeing these overweight people slaving away on the cardio machines going so slow expecting to lose weight.

    People have to realise that to lose weight they just need to reverse engineer how they got their in the first place. You got there by moving too little and eating too much, so by simply moving more and eating less, the lbs will drop.

    HIIT will definitely speed up the process, but its best if overweight people build up to this level of fitness first as they could get injured.

    1. Agreed Michael. As long as people start moving more and eating less, they’ll lose weight, and they don’t even need to do HIIT to get results, it just speeds things up a bit.

  3. Hi Keith, very comprehensive post on interval training. I like your intro…lol. I love HIIT whenever I need that extra oommph after my strength training session. But, I definitely do not prioritize it. For people who still have a lot to lose or need to do something different to break a plateau, this method definitely works.

    Anna D.

    1. Thanks Anna. HIIT is never a #1 priority for me too, diet will always be more important than anything else but for that need that extra push, HIIT is a great tool.

  4. Hey I was wondering if you could advise me on what to eat before and after HIIT.
    I do my HIIT at 3pm right after I return from college.
    I usually have 170g of skimmed yogurt with 1 tablespoon of oat bran an hour before, 600 ml of water during the workout and 100g of chicken breast soon after the workout.
    Is this good or is there something better I should have?

    Also I am not doing any weight training as I know I won’t keep it up for long.
    Should I do more HIIT? Maybe 4 or 5 times a week?

    And would it be okay if I did HIIT on 3 consecutive days and took the other 4 days off or do I need to have the rest days btwn each HIIT sessions?

    Thank you 🙂

    1. Hey Ace,

      Before workout – Try to take some caffeine beforehand, but don’t eat anything heavy. In fact, you can do the workout fasted if you want. But if need to eat something, stick to something light like a piece of fruit. For post workout, what you said is fine.

      Also, you really should try to do some weight training. If you don’t like to lift weights, you can do bodyweight exercises, but don’t just do HIIT alone.

      When doing HIIT, I wouldn’t recommend 3 days in a row. That could really lead to overtraining. For now, just stick with 3-4 times per week with at least 1 day rest in between.

      Hope this helps
      -Keith

  5. Hi I wanna do hiit cardio but I’m afraid it will
    Make me get bulky , I’m trying to go for the long,
    Lean and slim look. Will this give me fast results without
    Building muscle? If anything I want to lose muscle in my legs
    To make them look smaller.

    1. HIIT won’t make make your legs bulky. If anything, it’s the perfect way to get that lean and slim look you want.

  6. Hi Keith,

    which option is better in terms of maximizing fat burn ?

    1) hiit using treadmills or
    2) hiit using bodyweight exercises such as mountain climber, burpees etc

    Thanks Keith

  7. Keith

    Thanks for the reply.

    currently, i am doing hiit on the treadmill but not sure if i do it the right way.

    step 1: walk 4 mins at speed of 6.5 (heart rate around 120)
    step 2: jog 4 mins at speed of 9 (heart rate around 150)
    step 3: sprint 2 mins at speed of 12 (heart rate around 170)
    i repeat this 4 times.

    the reason i do this so that i don’t have to keep pressing the button which is pretty troublesome.

    But then again, is this the right way ? sometimes i feel that i might be resting for too long which is 4 mins of walking in each cycle.

    or should i do as per below:

    step 1: walk 2 mins at speed of 7
    step 2: sprint 1 min at speed of 13
    repeat 4 times

    what is your advise ?

    thanks keith

    1. 2 minutes for sprinting is way too much.

      If you don’t like pushing the button, try Approach #2 which I highlighted in the article.

  8. Hi Keith,

    I have a couple of doubts I want to clear out . Here they are :

    1) Can I do HIIT on a exercise bike as follows : 15 seconds ride as fast as possible, then 10 seconds of rest. During the rest period, should I take my leg completely off the pedal or just slow down ?

    2) What should be diet I should follow ? I go out with friends to McD and KFC during weekends. I have like 1 burger , chips and a coke. or 2 pieces of chicken frm KFC or when I go to the movies I have a coke and popcorn.

    Otherwise I have a light breakfast, drink lots of water, lunch I take fruits and dinner would be very light too.. Shall I continue , or should I change anything ? My height is 5’6″ and I weigh 191 pounds. How much would be the ideal weight ??

    Thanks in Advance.

      1. I actually would be happy, if I can pull down at least 10 kilos, which should be in the range you said, i.e. 20pounds. and I would be happy! And you’re sure this technique would help right ?

        How long to achieve success, if I do it 3ce a week from the coming week ?

        1. well you can’t just do hiit, you need to do resistance training as well. As for how long, it varies…You can probably expect to lose 1-2 pounds per week realistically.

  9. Can you give feedback on how I would space HIIT with strength training workouts ensuring enough rest periods for both workouts. Also, would it be wise to do HIIT after a leg workout or is this going to. Break down the muscle I’m trying to build? Thank you.

  10. Hi from Romania:)

    Great article, being new to HIIT I just have a few questions:

    1. Is it really important to do my weight training before I do my HIIT? I tend to do it after so I still have enough energy for lifting.
    2. On my HIIT off days should I refrain from any cardio or can I hit the treadmill/bike for, let’s say, 25 minutes?
    3. I’m on the ketogenic diet, lost about 17kg (~37,5lbs) in about 2 months just by dieting and hitting the treadmill and bike for about 1 hour daily. Now I weigh 80kg (176lbs), I’m happy with my weight I just want to lose what’s left of my abdominal fat and maybe add some muscle. The question is, does keto and HIIT get along?

    Thanks!

    1. @Raul,

      1. After is fine as long as you’re lifting with the same amount of intensity.
      2. If you really want to do some cardio, just stick with something low-intensity…like walking.
      3. Keto is fine, but it is really low in carbs so if you feel like you’re running low in energy, then I would increase your carb intake significantly.

  11. Great post! My question to you is: is it okay to do tabata sprints right after a weight lifting workout? The schedule I have right now is Mon Wed Fri I hit the heavy bag and Tue Thurs Sat I do 3 compound workouts each workout 3 sets 5 reps and the 5 minute drive home I stop at a park and do sprints, so sprints Tue Thurs Sat after weight lifting. What are your thoughts? Am i over training with this workout Mon through Sat?

    1. Well I don’t know your exact M-F workout, but as long as you’re not killing yourself with the training, it shouldn’t be a problem.

  12. Hi!!

    I am trying to lose quite a bit of weight.. 60 lbs. Currently, I am doing 4-5 days of HIIT. Is the 2-3 days of HIIT only for those without large weight loss goals? Or everyone? lol

    Thanks! 🙂

  13. Hello. Thanks for the article. So since hiit should only really be done every other day, would you recommend switching it off with strength training to maximize fat loss? and if so, do you have certain type of strength training regimen you would recommend to go with it?
    thanks

    1. Honestly I would do it the after your strength training so you have the next day to recover. As for a specific routine, I outlined a few on my site…but in general stick with compound movements like bench press, chin ups, and rows and do them in the 3-5 rep range.
