9. Alternate between Lower & Upper body interval workouts (Also Optional)

10. Always try to beat your last interval workout

5 ways to beat your last interval workout to lose weight even faster
(Or 5 ways to make your interval workouts tougher)

  1. Make your easy parts shorter or rest less after doing the hard parts of your interval workout.
  2. Make your hard parts longer than 40 seconds.
  3. Do your interval workout longer than 40 minutes if the full 40 minutes isn't already kicking your ass.
  4. You can workout harder during your hard parts. (ex. Run or walk faster, walk on an incline or wear a weight vest)
  5. Keep a fat loss workout log to track how fast you were going, how many calories you burned and/or how many miles you did to have something to look forward to beating in your next interval workout.

Quick summary of the 10 rules to lose 10 pounds every 3 weeks with intervals

Examples of High Intensity Interval Workouts

5 Reasons why high intensity interval training (or HIIT) burns fat faster

1. You'll Triple Your Fat Loss

In this study from Australia… A group of women Lost 3 Times more fat doing ONLY 20 minutes of HIIT 3 days a week than a group of women doing the normal 40-minute steady pace cardio workouts like walking at 3mph

They lost three times more weight as other women who exercised at a continuous, regular pace for 40 minutesUNSW Associate Professor Steve Boutcher     see article

2. HIIT Increases fat burning hormones

3. HIIT Suppress your appetite or you won't be that hungry afterwards

This study confirms that you'll eat less calories during the 38 hours after finishing a high intensity interval workout and The less calories you eat = the faster you'll lose weight &…

HIIT reduces your appetite by decreasing the amount of ghrelin in your body & Ghrelin is a 'fat gaining' hormone that increases appetite making you want to eat more.

4. You're losing weight while you sleep

HIIT creates a greater "after burn effect" than most other workouts which basically means you continue to burn calories (or lose weight) for hours after you've finished a HIIT workout (see more about the After burn effect) and You'll burn an extra 225 calories after doing a HIIT workout according to this study

5. You'll definitely lose more belly fat

Study after study clearly shows you'll lose more belly fat doing HIIT than any other weight loss exercises (this study confirms you'll lose 48% more belly fat) so HIIT is about the closest thing you'll get to spot reduction.

So What is high intensity interval training?

An interval workout is a high intensity workout where you keep switching back and forth between doing something hard for a short period of time and then something that is easy for a short period of time so if you did a high intensity interval workout on a treadmill for example…

If you still don't understand what high intensity interval workouts are please look at the examples on this page or watch this video

Hi Adrian,
I've been doing the interval training on ellliptical at the gym but when it's time to slow done / rest , the machine starts to beep/pause since i'm not moving or hardly moving at all and it seems to get peoples attention at the gym.
During rest period do I complety stop or is ok to keep going at slower pace to keep machine from shutting off?

you can go at a slower pace during breaks

Hi Adrian,

I want to start interval training I know you recommended to do 2 HIIT a day but I wanted to know what's the time amount you recommend for each interval training. For example the jumping jack 10 minute training and then the 20 minute running from chair to chair challenge. Or two 20 minute ones or two 10 minute ones just not sure the amount of time each should be.

Thanks in advance.

as long as its 10-to-40 minutes that kicks your ass

I am 5'2 and 120 lbs. I lost 10 lbs doing the metabolic balance diet which was awesome. But now am stuck at that weight. I am eating very healthy and all right things drinking water etc. will doing HIIt training for 20 minutes help me lose the weight. I am pretty active play tennis twice a week, do an hour of circuit training and hot yoga once a week and regular walking for 2-3 miles a day. But the 5 lbs is not coming off.

Hi, I stumbled on your website. I'm 56, 5'2" and 144lbs. All my life I never could get above 98lbs until age 35 then I eased up to 120 which was a nice weight for me. Last year menopause smacked me in the face and hello 24 more pounds that must go! I have a treadmill that I have started doing intervals on... I have never been a fast runner even though I was always athletic so I do 15 minutes alternating from 5mph to 2.5mph every other minute, no break. Then immediately go to a 15 minutes of 3mph High incline to a lower incline every other minute, no break. Then I do the 30 minute routine later in the day. Im wasted after these and sweating like crazy and feel like I've had a shot of adrenaline but don't really want to move much for awhile. Do you think this routine will help me get rid of the 24lbs? it just seems slow to me but I'm flat out running at 5mph! Plus everyone tells me I'm wasting my time because once menopause hits you're stuck with the extra pounds. Thanks

if the workout is kicking your ass then no... you are not wasting your time but what about your diet?

February 12, 2015


Ive cut out a lot of bread and sugar. I try to eat a scrambled egg for breakfast but thats usually around 11:00am... sweet potatoes and squash. I really don't do a calorie count. I try to go for proteins. I swear to god I could have killed for a peanut butter cookie last night but I jokingly just smelled of it (big whif). Then I didn't want it. Ive never had to watch what I eat until now so everything in moderation.

Btw: I tried "Insanity" last September but got very bored with it really fast. Some of it was ok and some of it seemed impossible to keep up with. So I did nothing until January (probably some depression). Started 1/5/2015 intervals on my treadmill when I got the flu and just didn't have the energy. So I started back this past week with a vengeance. My biggest problem is motivation but just posting here has given me the push I needed.
thank you.

more motivation here but do you know your total calorie intake?

Hi Adrian,
I am 77 year old male, been working out since 1968 (snow sport fanatic). I have prostate cancer , in menopause due to Zoladex implants. so I sympathise with Susan. I also have a mechanical knee so jumping, lunges & squats are out, I am building up legs on the 45%hack machine pushing 200kilo x 20 reps up & down pyramids from 80 kg. I need to loose the belly fat. I interval (fartlek) train on the bike 10minutes on & then flat out for 10 secs. hor 30 minutes x 2 days then workouts, upper body one day, 1 day rest then lower body, i day rest then 1 hour cardio. Weight is not going. Shouold I do exhaustion sets?

I don't keep a diary but I usually eat the same things all the time. The last time I wrote it all down it averages about 1200 calories a day in a week. Sometimes a little less. My low range is 800 a day to the high end of 1600 in a day. I ate too much junk back in the fall months but have given it up now. I know you would say I'm wrong here but I seem to get results from what I eat not how much but I've never had a large appetite. No pasta! No dairy, except eggs. Nothing that has flour in it.

February 13, 2015


All that typing and it looks like it didn't post so here's the short version. A weekly average of 1200 calories a day.

February 13, 2015


Thanks for the motivation page Adrian but I can "poo poo" those things away very easy. I'm the queen of "good intentions"! I'm a slightly plump kid that just realized my true age this past year. Sux, so I'm gonna really try this time.

Hey Adrian,

Will the ski step and jumping jack workouts increase calf size?

My calves are naturally bulky so I'm trying to avoid that.

I have fatty thighs, is there anything I can do to burn that fat in that particular area? I am not looking to have small thighs just smaller and more toned thighs

Adrian Bryant

just lose weight all over so use this workout and this diet

January 20, 2015


Loved this article...just discovered interval training...I'm doing 30-35 mins and can burn 500-600 calories by doing the following on a treadmill

Incline @ 2.5
1-3 mins - speed on 5 as warm up
3 - 20 mins - 30 secs on/30 off - speed on 12
20 - 25 mins - incline @ 15 - speed on 6.5
25 - 30 mins - 30 secs on/30 off - speed on 12
30 - 35 mins - cool down

How many times a week should I do this...

Thanks for great tips and facts ...I'm 46 and this is definitely working for me and fat burning, toning and fitness...I feel amazing after my 35 min work out.
