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.
Hi, I’am 25 year old woman. I have a trainer who makes me do Lower body exercises…. mainly squats, lunges ….. leg rises …. leg presses, leg raise with ankle weights etc etc for 1 hr/ five days a week. I have been doing this for 45 days but I don’t seem to have lost any weight or inches. I am 5 feet 6 inches tall weigh about 141 lbs….. Please let me know if it is okay for me to do 20 Mins of HIIT on a treadmill after my workout with the trainer . My ultimate goal is to loose 15 Lbs and get well toned slim legs (with a thigh gap).
It’s not necessarily about your workout, it seems like your diet may be your problem.
Hey…… But I have been eating the same as when I did not do any workout all. In fact I have cut down on my diet a littel bit
How often should soccer players do HIIT ?
soccer is already a rough form of HIIT, no more than 2x per week.
Hi, great article. Huge fan of HIIT. Since Bulking I’ve almost completely stopped HIIT training. Recently, I’ve injured my shoulder and its going to keep out of the weight lifting for a month. I’m going to workout my legs every five days and I am going to go heavy on HIIT to start cutting. Why bulk when I can’t really lift anymore.
Having said all this, since I am only lifting 1-2 times a week (only legs), can I do HIIT more than 3 times a week? 4 or 5 times maybe? and can you do HIIT on two or even 3 consecutive days?
I wouldn’t. I would lift at least 3x per week.
I have just starting doing hiit on the treadmill . I weight 140 pounds and I wanna lost 15 pounds ..I usually do it for 30 mins and I try my best to eat healthy . Will I lose weight by doing hiit for 30 mins everyday ?
you lose weight via a calorie deficit in your diet. Use HIIT as a bonus.
What speed in the treadmill do you recommend for the work and rest periods? I usually do 30 seconds work at 6.5 speed and 1 minute and 30 seconds rest at 2.5 speed for a total period of 20 minutes. Is this enough? I do this after about a 40 minute lifting session. Thanks.
it varies for everyone.
For work – to the point that you’re sprinting
For rest – to the point you’re walking at a normal pace.
what should the speed and incline be for sprinting?
i just like a slight incline – typically no more than 2.0 on most machines which is like 10-15 degrees.
speed is dependent on the person and should be high enough so that you’re performing an all-out sprint.
how many days a week should I do HIIT on a treadmill
I’d start out with 1-2x
Keith,
I like to run every day and i am doing weights three times a week. You mentioned to do HIIT just 2 times a week, can I still do normal runs on other days?
Also, can I pick my own running time and walking time or it has to be 30 seconds / 90 seconds?
Yes if you enjoy it that’s fine. If you find the running cuts into your other workout’s intensity, then increase calories (specifically carbs)
i have started incorporating hiit treadmill into my workouts and i always feel it in my hips, …i find it hard to give it my best since i feel i like i can run faster but when i take my speed high my hips hurt. any advice?
try doing some leg swings to loosen up your hips beforehand and make sure to warmup properly.
are body weight hiit ok to do 5 days a week?
what’s bodyweight HIIT?
I want to add hiit training alongside weight training and also have time issue so is it good to do hiit right after your workout irrespective of whatever bodypart i train
you shouldn’t do it everyday, only 1-3x per week.
I love running (and weights not so much) and have recently switched up to HIIT training on the treadmill. I usually do 1 minute at 3.6 and 1 minute 8.0 or so for about 45 minutes to an hour about 3 days a week. I’m a female (5’6) and weight 123 lbs, but I am struggling to totally get rid of my excess belly fat (yes, I am on a healthy low calorie diet as well). Will my persistence pay off, or do I really need to include weight training? Thank you for your time! 🙂
you don’t build muscle with HIIT, so you make the call.
Great article! I’m currently restructuring my workout plan due to me wanting to lose weight. Traditionally I’ve completed the HIIT workouts on the Nike Fitness App And have ran about 3- 3 mile runs a week. I want to incorporate more HIIT But I’m unsure whether doing weight-lifting HIIT 3 days per week and cardio HIIT the other 3 days would be overdoing it. Should I limit to either weight or cardio HIIT? If so, any suggestions on which would be best? And traditionally, on non-HIIT days are you suggesting to just do regular weight lifting?
Many questions, guess I’m a bit confused on the weight lifting & cardio balance in how it plays out with the steady state & HIIT balance… Thanks!
yes i think that is overdoing it.
You can do weights 3x per week and HIIT 2-3x per week. I like HIIT on lifting days just to get it over with.
Sir i my weight is 125 kg and age is 20 and height 5 feet 10 inch plzz suggest me workout plan for a weak
I need to get over this bulk i have already reduced 20 kg but i 1 year
focus on your diet more than anything else and eating in a calorie deficit.
I have been doing HIIT for about 6 weeks and love the results. I need to do something on my off days….what types of exercises won’t work against me? Yoga, walking? I have a desk job and really just want to sustain my commitment to move daily, even if low intensity.
yoga and walking is fine.
