Find out the secret interval training workouts used by Men's Health magazine experts to help their clients burn fat and lose their love handles.

Interval recommendations have ranged from 15 seconds to 5 minutes (these are known as aerobic intervals). So let's take a look at each interval recommendation and all those in between.

1) 15 Second Intervals

The great thing about 15 second intervals is that you'll be able to work at a very high rate (almost near your maximum power output), as long as you get adequate recovery between work intervals. The downside is that it is very difficult to do 15 second intervals on machines, because it takes a long time to "build up" and "bring down" the machine settings to the correct speed.

Intervals are for advanced fitness levels. Your rest interval should be at least 15 seconds long, and can be as long as 60 seconds. The longer you rest, the harder you will be able to exercise in each interval.

2) 20 seconds on, 10 seconds off

This method is known as the Tabata protocol, after the Japanese scientist that published a study on this routine. This is hardcore. Not for the faint of heart. If you are a beginner, try easy interval trainig.

Alwyn Cosgrove and Craig Ballantyne use interval training because it works. Again, it would be very difficult to perform this type of interval training on a machine, due to the time lag as you increase or decrease the settings. And finally, these too should only be performed by above average fitness levels.

3) 30 Second Intervals

The Turbulence Training workouts tend to use a lot of 30 second intervals. Beginners will rest up to 90 seconds between intervals, while advanced fitness levels will rest 30-60 seconds. The longer (relative) rest allows you to work harder in each successive interval (i.e. you'll almost be able to match your performance in the first interval with each following interval). Short rest intervals (as in the Tabata protocol) will lead to a dramatic drop-off in performance with each interval. You can easily do the 3-second intervals on any machine.

4) 45 Second Intervals

These intervals are proven for fat loss, in addition to being effective for many team sports (such as hockey, soccer, basketball, and rugby). I have used 45 second intervals extensively in both areas of training. Short workouts, but tough workouts. Your rest intervals will feel like they go by so fast. Use 45-90 seconds of recovery between intervals. Do 3-6 intervals per workout. Get ready to be fitter and leaner than ever.

5) 60 second intervals

Similar to the 45 second intervals in benefits and toughness. Rest 1-2 minutes before starting your next interval.

6) 120 second intervals

These are now officially aerobic intervals, and can be used for both fat loss and improving aerobic capacity for sports and running. A great way to achieve two fitness goals at once. Exercise for 2 minutes and then recover for 2 minutes. Repeat 6 times. These workouts take longer (obviously), but can have a role in changing your body and improving your performance.

7) 5 minute intervals

Same strategy as with the two minute intervals. This really increases your workout time, so these are only used with serious endurance athletes.

Beginner vs. Advanced

If you are thinking that these intervals all sound "too intense" for you, please don't worry. Interval training is all relative. You don't have to sprint for your life in each type of interval. Instead, just work at a slightly harder than normal pace. By the end of the interval, you should be getting tired, but you shouldn't be gasping for air. Start conservatively and you will get the hang of it.

For example, if you regularly use level 5 on the stationary bike for 30 minutes continuously, you might try doing a 1 minute interval at level 7. Try that for an interval workout and let me know how it goes.

I really like to use short bursts of exercise lasting no longer than a minute. These have been the staple intervals in my Turbulence Training workouts since the first workout was designed back in 2001. But again, I think you will get your best fat loss results if you vary your interval training workouts - just like you must vary your strength training workouts.

Without fat burning intervals, you might never burn belly fat.

Best Ways to Burn Belly Fat

I often get asked, "What's the best way to burn fat and lose my belly?" People want to know if aerobics is better than strength training, or if traditional cardio exercise is better than intervals.

Well, to say I've done them all would be an understatement.

With over 15 years experience helping others, training myself, training for sports, spending countless hours in the gym, AND actually conducting laboratory research studies on different exercise methods, I'm pretty confident in knowing what works and what does not.

But first of all, I want to frame my responses. I'm going to talk about what works for people that have a limited amount of time to exercise, mostly because I expect your readers don't have 90 minutes per day to devote to a workout, unlike the typical audience of a fitness magazine.

That's why there is a huge disconnect between some of the information found in magazines and the ability of the reader to apply it to their lives.

We just don't have 6-8 hours per week for exercise, nor do we need it. If you're a triathlete, you might need that, but not someone that just wants to lose fat and gain muscle.

Having said all that, the bottom line for getting a better body is...

Use bodyweight exercises to warm-up, strength training supersets to build muscle, and then finish your workout with interval training to burn fat in a short amount of time. I've structured my system so that you are in and out of the gym in 45 minutes, three times per week.

You'll do 5 minutes of bodyweight exercises to warm-up. This is a much more efficient approach than spending 5 minutes walking on a treadmill, which really doesn't prepare you for anything except more walking on a treadmill.

Then we move into the strength training supersets, where we use two exercises performed back to back with minimum rest between each. This cuts our workout time, while still giving us maximum results. We only need 20 minutes for this, and we'll use basic exercises, and sometimes even more bodyweight exercises, depending on the client's goal for muscle building.

And finally, we'll do 18 minutes of interval training. A warm-up, followed by six short intervals at the appropriate fitness level for the client, interspersed with short periods of low-intensity recovery. Finish with a cool-down. And that's the workout. Again, about 45 minutes total.

Compare that to what most people do, which is run, jog, cycle or use the cardio machines for 45 minutes straight. Sure, that will burn calories, but it doesn't build a better body.

In fact, there are a few "dark sides" to long slow cardio, including less-than-optimal results, the potential for overuse injuries, and it is an inefficient form of exercise. If you only have 30-45 minutes for your workout and you spend it all on a cardio machine, when are you going to train the rest of your muscles and sculpt a better body?

So the best way to burn belly fat is with a combination of strength training and interval training. It's fast, it works, and it's fun!
