Best HIIT Workouts For Rapid Fat Loss

If you’re a regular reader of my blog I’m sure you’ve heard me on numerous occasions praise High Intensity Interval Training aka HIIT workouts, which have been proven to be the best for rapid fat loss.

Basically, HIIT workouts are a version of cardiovascular training using alternating periods of high intensity work with maximum effort followed by lower intense periods of lower intensity work.

In this study published in Applied Physiology, Nutrition and Metabolism the researchers found HIIT workouts increased fat burning by 60% in the participants over a 3 week period.

Another huge plus for HIIT workouts is the shorter amount of time you have to spend doing the actual workout.  While most people try to lose fat by jogging on the treadmill for half an hour you can be done in 20 minutes while burning a ton more fat than them too.

This is going to come with a hefty price tag as you’re going to have to work your butt off by sprinting during your HIIT workout.

But if you can hang for 20 minutes than you’ll reap the full benefits of this HIIT workout routine.

Best HIIT Workout For Fat Loss

hiit workouts

If you’ve ever seen the sprinters body type then you’ll know they have a very toned and athletic physique that’s also very attractive.

And they do all of their training by alternating between high-intensity sprinting and low intensity running or jogging. This is HIIT.

If you’ve also ever seen a marathon runner’s body they have no muscular development leaving their body looking unattractive even though it appears to be thin.

High-intensity interval training is going to be much more effective for fat loss when compared to low intensity aerobic training.

This 2015 study found HIIT training to be superior to endurance training for improving VO2max of healthy, young middle aged adults.

And in this new 2018 study participants shredded 4.3% bodyfat after 7 weeks of HIIT workouts.

HIIT workouts are superior to endurance training as the former puts your body into an oxygen deficit. This basically means your body needs more oxygen to return to its normal resting state therefore you’ll be burning more calories. Oh yeah!

When your body gets in this oxygen deficit state it has to work very hard to bring it back to its normal levels burning more calories to do so.

This is known as the Excess Post-exercise Oxygen Consumption (EPOC), but I like to refer to it as the Afterburn.

afterburn training

Afterburn Training = Massive Fat Loss

One of the biggest fat loss advantages of HIIT workouts is the Afterburn effect. This is where your body can keep burning fat way longer after you’ve finished your workout.

Just imagine yourself sitting on the couch the night after completing a HIIT workout having your fat burning engines going full force even though you’re not doing a thing.

Having your metabolism elevated throughout the next day and a half is like having a side business that automatically deposits money into your checking account while you’re sleeping. Wouldn’t that be nice!

For a while the EPOC was known as the oxygen deficit, and it’s the recovery process your metabolism goes through to go back to the pre-exercise levels.

With low intensity cardiovascular exercise it doesn’t take very long, but with the best HIIT workouts it can take up to a day and half.

afterburn training

Feel the burn!

As your body burns calories around the clock you can fully expect your fat to practically melt off your body.

This is the best exercise investment you can make for you body. You’ll be able to do the work for only 20 minutes earlier in the day then have your body burning fat while you lay on your bed watching TV and playing with your smartphone.

The good news is you can keep doing these HIIT workouts and still get the Afterburn effect.

As long as you’re keeping the intensity high and varying your workouts your body will continue to burn calories with the EPOC as it works to bring itself back to a pre-exercise level.

Just make sure you don’t end up burning yourself out as these workouts can be pretty intense on your body.

Every once in a while if I have the time I’ll go on a long run outside just to mix things up and give my body a break.

But you won’t get near the same benefits of an Afterburn workout if you’re just hopping on an elliptical of a while.

The intensity isn’t nearly the same as one of my best HIIT workouts below. They’re the fastest weight loss workout plans for men and women.

The Awesome Benefits Of HIIT

best hiit workout

Now you know the fat burning machine your body turns into with HIIT workouts there are some other awesome benefits.

The big one is you’ll increase your levels of Human Growth Hormone (HGH) up to 450% for 24 hours to help you burn more fat, build more lean muscle and it’ll even help you look younger.

Don’t worry about getting huge bulking muscles if you’re female. At most you can expect to be thinner, leaner and more physically attractive with your new toned body.

Unlike traditional steady state cardio the lean muscle you have won’t go away when you’re doing HIIT workouts.

Your hard earned muscle will help to burn more calories while toning and shaping your body.

One thing I really love about High Intensity Interval Training is you can do it literally anywhere. Whenever the weather is nice and want to mix things up I’ll go outside for my workout.

It’s a great way to get some sunshine and enjoy your workouts instead of being stuck in a gym all the time.

You’ll love how the workouts for HIIT are challenging and always different.

A lot of the time when you hop on a treadmill for a jog it can be super boring. You’ll find enjoyment out of pushing yourself with a new HIIT workout every time.

The one thing about these challenging workouts is they always keep things fresh!

The Perfect HIIT Mix

High Intensity Interval Training should be done around three days a week on its own or for about 10 minutes following Metabolic Resistance Training (MRT) workouts.

It will be better for fat loss if you do them afterward your weightlifting workouts. Always make sure you warm up properly for 5 to 10 min. at a jogging pace before going full HIIT and then cool down for another 5 minutes at a very low pace.

Ideally you would be doing High Intensity Interval Training out in the real world where you can fully sprint such as a high school track or hills at a park.

If you don’t have access to an open area such as jogging track you could easily use a treadmill or if you have bad knees you could use a bike.

The good thing about High Intensity Interval Training is you can do it using basically any kind of cardio including swimming, jumping, basketball, stair sprints, etc.

high intensity interval training workout

Heck you could even do a work set of sprints and then on the next work set throw in some rope slams. Or you can do burpees, kettlebell swings, box jumps or medicine ball slams.

All the different tools and exercises you can use in a HIIT workout making things fun and are literally endless.

Just be sure to keep alternating them for a fun way to mix things up so things don’t become stale. When it comes to working out keeping things fresh with variety will make your workouts more enjoyable otherwise it’s easy to get bored with doing the same old routine.

The more fun the workout is for you the more likely you are to do.

As long as you’re able to crank your heart rate sky high with alternating periods of intense exercise then you’re definitely doing a killer HIIT workout.

Make sure after your High Intensity Interval Training workouts you also use a post-workout recovery drink such as protein shake.

The last thing you want after all your hard work is to throw your results out the window because he didn’t give your body the nutrients it needs to properly recover.

6 Week HIIT Workout Plan

usain bolt hiit workout

Warm up by jogging on the treadmill for a few minutes, doing some jumping jacks or riding a bike to get loosen up your muscles and tendons while increasing your blood flow priming your body to crush the workout.

Do each weeks workout 2-3 times per week preferably on non-consecutive days. If you’re combining this workout with resistance training then make sure you do this HIIT workout after you’re done with the weights.

A good rule of thumb is to find a sprinting intensity that feels like a 9/10 on your difficulty scale. Then find one that feels like a 5/10 for the lower intensity part of the HIIT workout.

If you can still carry on a conversation on the sprinting part then you’re probably not going hard enough.

Here’s the HIIT workout breakdown…

Week 1:  20 minutes; 20 seconds ON / 40 seconds OFF

Week 2: 20 minutes; 30 seconds ON / 30 seconds OFF

Week 3: 20 minutes; 45 seconds ON / 30 seconds OFF

Week 4: 20 minutes; 60 seconds ON / 60 seconds OFF

Week 5: 20 minutes; 60 seconds ON / 45 seconds OFF

Week 6: 20 minutes; 60 seconds ON / 30 seconds OFF

Here I am demonstrating how to properly use the treadmill for HIIT workouts so you can burn massive amounts of fat without hurting yourself.

Wrapping Up My HIIT Workout Routine

Again, make sure you take a few minutes following the workout to cool down to gradually bring your heart rate back down.

I would definitely encourage doing these HIIT workouts in addition to resistance training. It’ll would probably be better if you did each HIIT workout on alternating days.

Based on my research and from personal experience with my clients HIIT workouts are going to outperform long steady aerobic training every single day of the week.

When it comes to losing belly fat aerobic training just isn’t as effective. I’m not saying traditional steady state cardio isn’t going to burn fat because it will.

It just turns out HIIT will work better while taking less time and being more fun.

But everybody is different so in the end if you really love going on long runs and bike rides for your workouts then in the long run you’ll be better off doing just that.

In the end, either training program isn’t going to burn all the fat you want off your body if you’re not following a proven nutrition system. I personally designed The Flat Belly Formula nutrition system to maximize fat loss along with HIIT workouts to give you the best of both worlds.

You can’t out train a bad diet so it’s absolutely vital you’re watching what you put into your body.

Then mix in some of the best HIIT workouts above and you’ll turn your body into a fat burning machine.

    May 14, 2011 at 7:15 pm

    what exactly is the “seconds on” and “seconds off” in the 20 minute hiit workout? is it the amount of time you stay in your heart rate zone once you reach it?


    • Josh Schlottman

      May 23, 2011 at 3:42 pm

      Hey Bill,

      It’s actually the amount of work to rest ratio you’re performing.

      So the “seconds ON” would be how long you would be sprinting and the “seconds OFF” would be how long you jog/walk.

    Is there other workouts besides using a treadmill?


    • Josh Schlottman

      May 23, 2011 at 3:43 pm

      Hey Jill,

      You could apply these same methods to other types of training as well. For example you could do burpees or jump squats for the ON time and then do jumping jacks for the OFF time. Also other cardio forms apply such as swimming, biking, etc.

    May 20, 2011 at 4:02 pm

    Josh, you are amazing! This is soooo awesome. It hurts like heck, but it’s so effective. I did it on the treadmill first, but the second time I was forced to use the eliptical as all the treadmills in the gym were taken (is summer coming?????). It works there too. I think you could use this with just about anything – stepper, etc. but I do prefer the treadmill. Thank you so much for posting such great tips!

    can you give an example for the OFF/ON periods?
    thanks a lot


    • Josh Schlottman

      June 29, 2011 at 1:58 pm

      Hi Rose, for the OFF periods you would be jogging and for the On periods you would be doing an all-out sprint.


  7. Sam

    June 28, 2011 at 5:21 pm

    Just wondering about the part you said that it’s more effective to do 20min HIIT than 45min jogging, is this actually true? I’m altering my workout routine to add the HIIT plan in, but I want to be sure it’s a good idea before I shorten my cardio to around 20min instead of my usual longer cardio routine.


    • Josh Schlottman

      June 29, 2011 at 1:59 pm

      Hey Sam, yes sir. Just make sure you’re doing the HIIT workouts right and making it very intense.


  8. Ivan

    August 6, 2011 at 8:20 am

    Hi Josh,

    The OFF part is supposed to get your heart rate back down from 90% to around 65%, right?
    If so, 30 or 45 second of jog/walk would not be enough. I always need at least 3 min to get below 70%.

    What should i stick to when doing HIIT? The suggested time or the heartrate?

    Thanks very much for help and great work!


    • Josh Schlottman

      August 9, 2011 at 1:07 pm

      Hi Ivan,

      Yes the times in this workout are more examples then anything. If you’re going by heart rate then you should wait until it gets lower, try walking on the treadmill on the OFF sets to quicken how fast it lowers.

    hello i need to ask 2 things… that..30 sec on and off i got it..could u just tell me the speed on treadmill.and it comes to 60 sec so i have to 20 times right???and second thing..i just dolighter toning at home…so shall i do my toning after the treadmill or before


    • Josh Schlottman

      August 23, 2011 at 9:21 pm

      Hey poonam,

      As for the treadmill speed just find one that is very difficult for you. An example would be for it to be a 9/10 on the difficulty scale. It’s going to be different for everyone.


  10. amber

    August 14, 2011 at 10:28 pm

    what type and how much food should be consumed to make this effective and safe?


    • Josh Schlottman

      August 23, 2011 at 9:24 pm

      Hi Amber,

      A good rule of thumb is to eat until you feel like you’re 80% full. When it comes to fat loss it’s not necessarily how many calories you consume but what kinds of calories you consume.


  11. rabi

    August 15, 2011 at 5:02 pm

    I just have one question does that on and off time you put up include the time it takes for the treadmill to get to that max speed or slow down to the jog speed because, i find it takes like 5-8 secs so should i start countin when i hit the speed or just as soon as i type in the speed i should hold it from there


    • Josh Schlottman

      August 23, 2011 at 9:25 pm

      Hi rabi,

      I don’t include the time it takes for the treadmill to speed up to the desired speed I want.

    • Josh Schlottman

      September 16, 2011 at 7:05 pm

      Hi Corrie,

      I would just stay away from processed carbohydrates such as pizza and pasta while also avoiding bleach flour products such as bread. Most of your carbs should come from green vegetables and well cooked beans.

    Day 1 last night. Decided at 41, 5’6”, 178 pounds that I am tired of carrying around the spare tire. Started HITT doing 1 min on (6.0 mph) and 1 min off (4.5 mph). My diet included three eggs and ½ cup beans (breakfast), 2 plums (snack) protein and veggie lunch, apple (afternoon snack), and a protein filled dinner. Any suggestions or adjustments? I also need a good weigh training routine to mix in 3 nights a week. My goal – 18 pounds before the end of November (or sooner).

    Hi Josh,

    I am in my week 3 of HITT – Love it. I want to know if it is okay if I do it 5 days a week. And do I have to do any weights to lose weight? I have not yet shed any kilos but I only have to lose 14.3 lbs so I am patient. Some say I will only start losing after week 3, fingers cross. I try and warm up for 10 mins and then 20 mins HITT.


    • Josh Schlottman

      June 1, 2017 at 4:39 pm

      Hi Nadine, yes it’s ok to do 5 days a week. I would just be sure to focus on your diet. With this workout you will be burning a lot of fat but you will also be building some lean muscle which will help to tone you up. The big key is to make sure you’re dieting as well, and for that I recommend my Flat Belly Formula nutrition system.

    • Josh Schlottman

      January 30, 2012 at 1:45 pm

      Hi Vicky,

      Yes HIIT will help burn the belly fat but just make sure you’re also doing metabolic resistance training along with eating a clean diet like the one in my Flat Belly Formula book.

    • Josh Schlottman

      February 20, 2012 at 8:35 am

      Hi Andrew, you could also just keep increasing the intensity by adding an incline and increasing the speed of the treadmill if you’re using one.

      The good part about doing HIIT after your workouts is you’ll already be warmed up. So just hop on the treadmill and you should be good to go.

    • Josh Schlottman

      June 1, 2017 at 4:24 pm

      It’s not bad as long as your body can handle it. I usually don’t recommend doing it consecutive days because it’s so easy to get burned out.

    • Josh Schlottman

      March 13, 2017 at 4:22 pm

      I would begin to do variations of this HIIT workouts after 6 weeks. Meaning do different forms of HIIT, play with your work/rest time periods and sets as well as your rest periods. This way you’ll keep getting results and won’t plateau.

    Hi Josh,

    Im doing a full body workout 3x a week with weights. However there is no cardio involved, except for the warmup. I was therefore considering implementing the HIIT Workout afterwards (outside – not on a treadmill). However i was wondering if this might be too much for the body at once? And if I should perform the HIIT workout on the days “off” from the gym?

    Looking forward to your response!


    • Josh Schlottman

      March 8, 2017 at 4:14 pm

      I’d definitely would recommend bringing in some HIIT conditioning into your workouts. Even adding 10 minutes of HIIT on the end of your workouts would help you drop some fat quickly.


  29. Adam

    April 26, 2012 at 4:03 am

    Hi Josh, I’m just wondering is it full on 20 minutes of HIIT or can it be a 5 minute warm up at the start, then do the intervals, then cool down for 5 minutes?


    • Josh Schlottman

      April 30, 2012 at 1:22 pm

      Hey Adam, yes I actually recommend doing a warmup along with a cool down in addition to the 20 minutes of this HIIT workout.

    May 29, 2012 at 4:24 pm

    hey josh,
    when you say pair exercises like sprinting and jump rope, do you mean, sprinting 20 sec and jumping 20 sec, or sprinting 20 sec and jogging 20 sec then jumping 20 sec and jog 20 sec? thank you


    • Josh Schlottman

      June 19, 2012 at 9:22 am

      Hi Andrew, I would recommend just picking one of those and doing it for the HIIT workout. For example, jump rope for 20 seconds, rest for 40 seconds, then jump rope for 20 seconds, etc.

    This was a very informative article, great job! I have a question I have been doing a workout that goes something like this; I’ll do six 5 minute bouts of cardio, treadmill, rowing elliptical etc. and in between I do anywhere from 4 to 5 different resistance exercises. When I am on the treadmill I start at 6mph for 1 min, then 10mph for 30 sec then back to 6.0 for 1min 15sec then 10mph for 30 sec then down to 4mph for 1min 15sec then to 10mph for 45 sec. Is this a good plan? Is this a proper way to do HIIT training? Any information you can offer would be greatly appreciated. Thanks a lot!

      Hey Scott, sound like you have the cardio part right for the HIIT workout. I would try separating out your resistance training from your cardio though.

      Hi Gregory, follow the plan laid out above. Also make sure you’re following a proven fat burning diet program as well.

      Tabata traditionally follows a 20 seconds of work followed by 10 seconds of rest formula while HIIT isn’t restricted to any particular time format.

    Can I do this routine as a stand alone workout or do indeed to incorporate it with another workout routine? I am trying to lose weight.

      You can definitely incorporate it into another workout plan. In fact, you’ll get better results!

    Are the Insanity workouts considered HIIT workouts? These are usually 3 minutes on and 30 seconds off for 30-45 minutes.

      You can count the Insanity workouts as HIIT, but there are way better HIIT workouts out there you can be doing than Insanity.

    I would love to see examples of some of these. For example, hill running. 3X6? what does that mean? Also, some of the exercises have the name but no picture or description

      Good idea Amy! I’ll have to film some videos for these HIIT workouts soon. Thank you for the feedback
