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:
- Get on a treadmill and perform a light warm-up by doing a fast walk/light walk for 3-5 minutes.
- Slightly increase the incline to about 1.5.
- Amp up the intensity on the treadmill so that you performing an ALL OUT sprint for 30 seconds.
- Decrease the intensity so that you’re back to a walking pace. Walk for 90 seconds.
- 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.
- Get on a treadmill and perform a light warm-up by doing a fast walk/light jog for 3-5 minutes.
- Slightly increase the incline to about 1.5.
- 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.
- 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.
- Jump back to the sides and make sure you hold the railings. Rest for 10 seconds
- 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.
Thanks for the article. If I’m lifting 6 days a week, would it be detrimental to add 3 HIIT sessions post work out, every other lifting session? So monday, lifting + HIIT post workout, Tuesday strictly lifting, Wednesday lifting + HIIT, Thursday strictly lifting, so on and so forth..
Thanks
depends on the workout and your training level, but for a beginner, yes. If you’re super advanced, it heavily depends…if you do it, and you feel fine then that’s fine.
hi .. that was so helpful ..
but i have questions … i really need to know if what I’m doing is right .. BTW english is not my first language 🙂
im a girl .. 24 years old .. 83 kilos and 157 cm my cals on active day is around 1700 to 2000 calories .. and the days off around 1400 cals
currently i workout 3 days a week .. i complete month and half of these now
i work every sunday .. tuesday and thursday .. my schedule is
doing treadmill HIIT which is ( starting with 3,5 mph for 5 mins then 2 min on 4.5 mph and 1 min on 6.5 mph and ending as well with the 3.5 mph … with total of 36 mins )
after that i take a short rest then doing full body weight lifts .. using dumbbells between ( 2 – 3 kilos for upper body exercises / 4-5 kilos for lower )
and on machines i lift between ( 10 to 35 kilos ) lower numbers for upper body and higher for the lower
i lost about 2 kilos … but I’m still afraid 🙁 i don’t want to lose any muscles i really care about it and in the same time i need to lose a lot of fat !
Maintaining your muscle boils down to a few core things:
– Maintaining your strength
– Getting enough protein
– Not eating too few calories
As long as that’s happening, you’ll lose fat only.
Hi,
great article by the way!
I’m planning to shred down a little fat for the summer. I’m lifting 4x a week using Jim Wendler’s 5/3/1 as a template. It has 2 upper body days and 2 lower body days, like so, ABxABxx. If I wish to use a stationary bike and a rowing machine for my HIIT workouts, on which days do you recommend to use the bike and on which days the rowing machine, so that I would get optimal recovery time, to be able to still lift heavy? I was thinking of starting with 2 HIIT sessions per week for starters.
Thank you for all your effort,
Silver
i would stick my HIIT workouts after my lower body day. As for bike vs row, i really don’t think it matters unless the rowing interferes with your upper body day performance.
if i do HIIT training 3x times a week on monday wednesday and friday can i still walk on the treadmill in the days in between
if you really want.
Hi!
What is the best time of day to do HIIT? Is it true that the earlier you do HIIT in the day, the more you benefit from the fat-and-calorie-burning after effects? If I can only do my workout at 5pm, am I not reaping the full benefits?
Thanks!
H
doesn’t matter.
Thanks for the advice! So… I am a bit torn on what exactly I should be doing to lose weight and get shredded. I am a 22 years old female, weight about ~135lbs and measure 5’0ft tall. I would like to reach my ideal weight (i.e. 110lbs) in a short amount of time. I used to be very fit as I ran track and played various high intensity sports such as volleyball and tennis a few years ago. Today I consider myself to be mostly intermediate level, yet I can perform at an advanced level if I push myself. I am wondering if it’s possible to lose those 25lbs in 2 months by doing the following or if you rather recommend something different:
-Daily caloric intake: 1200
-HIIT Workout: 5x/wk
-Lift Workout: 3x/wk
(Thus, HIIT and Lift will overlap 3 times per week)
-2 days of full rest
My main goal is to shed fat and build lean muscle. I know you don’t recommend HIIT this many times per week, but I have been doing this for the past week and feel great.
It’s hard to follow anything online nowadays, with the booming of the fitness industry there is a lot of misleading information being thrown out there, making things complicated for people that are not 100% experts like myself. I just want to make sure that this workout is okay. Any help would be highly appreciated it!
You’re looking for a short cut by working out substantially more and eating way too few cals and that’s where everyone fails.
I would get at least 1350 calories. Cut back the HIIT to 3-4x per week.
Let your diet do 90% of the fat loss.
Great article! Just a question: I lift 3-4 times/week for about 1 hour and I’m planning to start HIIT to lose some bodyfat.
a. Should I eat something (protein or aminoacids) between lifting and HIIT?
b. Is the method of 3 minutes walking – 1 minute sprinting considered good?
c. If you run on a treadmill, there are some seconds that the treadmill tries to catch the desired speed (for example, going from 6km/h to 14km/h). Are those seconds considered sprinting? When does the true sprint starts?
Thanks!
a. no not needed.
b. I’d keep it at no more than 2 min.
c. doesn’t start till you’re at 14, but what you can do is step to the sides of the treadmill and increase the speed. Just be very careful when you step back on.
Thanks for the info! Just a couple of questions more and I’ll stop!
a. I usually have a shake of whey and dextrose post workout, should that sabotage HIIT if I have it after I finish, because of the insuline spike? The after 30-45′ meal of protein and slow burn carbs remains like it was or not?
b. My top heart rate is 188 beats/minute. Is 12-14k/hour OK for sprinting?
Hi, I see the information was very useful. I’ve a question. I like doing sprint after work out. But I’ve a doubt of losing muscles gain If I do sprint after work out. I want to get more muscles and size of my arms and chest.. Please make me clear that If I do sprint after my lifting weights will I lose the pump of my muscles? what should I eat after doing sprint in order not to loose the size of my chest and arms.
Please suggest. I will really appreciate the feedback from you.
With best regards,
JayR Pradhan
no you won’t lose muscle.
Do you recommend doing regular workouts except HIIT on the rest days? Or should it be a complete rest day with no workouts?
Yes, HIIT should never be your primary workout.
My wife is new to strength training and have her finally lifting heavier weights after some time convincinge her that it would improve strength and not make her look like he-man. Anyway, we are struggling with our metabolism and carry a large amount of body fat around 25-26percent for me and 23-24 percent for my wife, we both enjoy working out, but not sure if sprinting would be beneficial or right workout for us at this time. I like to get out and just run as fast I can and lift as heavy. I would love some assistance.
it depends on your current fitness level? If you are complete beginner to anything exercise related and find yourself out of breath even after walking a bit, then HIIT is too much for you.
Hi!
I’m a 20 year old female who’s always been a bit overweight. Right now, I’m 5’6″ and 154 lbs trying to lose some stubborn belly fat. Right now my schedule is every day alternating at home workouts like squats, crunches, etc and HIIT walking for 1 minute and sprinting for 15 seconds 10 times. I’m completely new to working out, and my metabolism is pretty slow. I eat clean and natural, and I’ve already lost about 5 lbs. I’m just wondering if this schedule is effective, or if you have any advice. Thanks!
it sounds fine, i would throw in some heavier resistance training but if you can’t, then that’s fine too.
Hello,
I have a question.
For the moment I run (No HIIT) about 3 times a week for 60 min.
What do you suggest is do? My biggest goal for the moment is losing fat.
Should I add HIIT? Or should I replace the normal Running? In stead of 3h Running, I only do Like 60min HITT a week???
Thanks
Lift weights and no HIIT 2-3x per week.
No one ever does HIIT for 60 min, it typically doesn’t last any more than 30 min.
I mean for the moment I run slowly for 60min. It’s better to change this to hiit for 20 mins? I will lose faster fat with less minutes?
yes, it will also result in a better body comp.
Dear Keith,
Thank you for all the right advice. Too much information out there, not quite sure what to follow. I am 5ft 2″ and weigh 153lbs. I am definitely over weight for my height and would like to lose 20lbs.
I aim to reach my goal weight and get shape by November which gives me roughly 5 months to train. Other than losing weight I would like to tone up as much as possible, focusing on my arms.
The problem is that I am travelling a lot in the next few months and thus do not have access to a gym or any sort of equipment for weight training.
I have started HIIT and have been doing it for the last 3 weeks. Could you please help me add more to my work out session to make it more effective considering I have no equipment handy.
I would really appreciate any help I could get and I am willing to give it all I’ve got to reach my goal weight.
you could do bodyweight movements like push ups, lunges, squats, pull ups, leg raises.
But in the end, it’s your diet that’s going to help you lose the most weight, not your workouts.
So over the past year I have lost 90 pounds just doing basic cardio on the treadmill. I fairly thin now but I have this obnoxious left over fat in my upper chest and around my waiste/back. So I pretty much have these fairly small man boobs if you will. My diet is also shit. I’m just wondering if I’m thinking too hard by considering hiit. I’m just trying to flatten these areas so they won’t hang out anymore, it’s not like I want a six pack or anything. Would you have any suggestions about the proper calorie intake and exercise. This is especially in regards to that small pocket of man boob fat I am trying desperately to eliminate, Thank you.
Are you lifting weights? I recommend actually training your chest and back and not just rely on different forms of cardio.
Hi, I started working out/going to gym and dieting this January. Recently I got more serious in it, so my plan for one week is currently Heavy lift, heavy lift, rest, rest, light lift, light lift, rest, etc. My calories for workout days is 1700 calories and for resting 1400 calories, is this considered fine? My height is 170 cm and weight 90 kg and my body fat % is around 30.
I’ve also considered adding HIIT to my training and would like to get some comments and suggestions on my plan, which would be: Heavy lift, heavy lift+HIIT, rest, rest, light lift+HIIT, light lift+HIIT, rest, and so on.
My main goal currently is to lose body fat and be somewhat lean, not bulky.
calories seem too low. I would be getting at least 1900 per day.
