Which Type Of Cardio Is Best For Fat Loss?

LISS (Low Intensity Steady State) vs HIIT (High Intensity Interval Training)

We all wonder what's the most effective way to lose weight, LISS (low intensity steady state cardio) or HIIT (high intensity interval training)? First off, remember that if you want to lose fat you will have to be in a caloric deficit.

Cardio trainings allow you to burn more calories, which will help you lose fat if you're in a caloric deficit. LISS and HIIT are both great for this purpose. They also improve your overall health: increase your endurance, lower your blood pressure, helps you burn calories, increase your metabolism and prevent heart diseases.

Now let's get into the core of this article: what kind of cardio exercises should you do to burn fat?

Losing fat and losing weight are two different things.

  • Losing fat: simply means you are trying to lose some body fat percentage for health purposes, feel better or look leaner.
  • Losing weight: weight loss can also occur when you've lost fat loss, muscle tissue, or simply water.

So think twice when you say "I lost 10 pounds in 1 week", it can be fat loss, muscle loss or simply water loss.

With LISS, you choose an aerobic exercise that you perform at 60%-70% of your maximal capacity for 20 minutes or more. The speed typically remains the same during the whole exercise.

Here are some activities you can do as a steady state cardio:

  • Walking
  • Jogging
  • Cycling
  • Elliptical
  • Swimming

Here's an example of LISS training:

With HIIT, you must execute a certain exercise at your maximal capacity for a short period of time (10-15 seconds for example). Then you rest for about the double of time you spent performing the exercises (20-30 seconds for example). You repeat this cycle 5-15 times depending on your fitness level.

Here are some exercises you can easily do HIIT with:

  • Sprints
  • Intervals on stationary bike
  • Battle rope
  • Burpees
  • Mountain climbers
  • Jumping jacks

Here's an example of HIIT training:

It's recommended to run between 30 minutes and 60 minutes in order to obtain good results. Research has shown that running for 45 minutes and more, seems to be the best duration in order to use fat as a source of energy. LISS is a simple way of burning more calories for beginners.

Research has shown that HIIT allows you to burn a lot of calories in a shorter time that steady state cardio. Since HIIT require general strength and activates more muscles, it can potentially help you build more muscle mass. You need to keep in mind that it will put a lot of stress on your muscles and joints. So if you're overweight or preparing for a fitness competition, you might want to stay away from HIIT so you can prevent getting injured.

At the end of the day, it's up to you to choose what kind of cardio training you want to do.

LISS and HIIT are effective for fat loss and they both have pros and cons:

LISS:

  • Pros:
    • Easy to do.
    • Doesn't put too much stress on your body.
    • Low risk of injury.
  • Cons:
    • It can be feel boring and repetitive

HIIT:

  • Pros:
    • Burns more calories.
    • Builds lean muscle mass.
    • It's shorter, so you don't get bored.
  • Cons
    • High risk of injury.
    • Puts a lot of stress on your body.

Let's summarize what we've just learned:

  • LISS: Low Intensity Steady State Cardio
  • HIIT: High Intensity Interval Training
  • Caloric deficit is key for fat loss.
  • Cardio trainings increases your endurance, lower your blood pressure, helps you burn calories, increase your metabolism and prevent heart diseases.
  • Weight loss and fat loss are two different things.
  • LISS are exercises that you perform at 60%-70% of your maximal capacity for 20 minutes or more.
  • HIIT are exercises that you perform at your maximal capacity for a short period of time in an interval fashion.
  • They are very efficient to help you burn more calories, you can add them both in your workout routine.

Frequently Asked Questions

The main difference between LISS (Low Intensity Steady State) and HIIT (High Intensity Interval Training) is the intensity and duration of the workout. LISS involves moderate, consistent effort over a longer period, while HIIT alternates between short bursts of intense activity and rest. Both can aid in fat loss, but HIIT may offer faster results due to the afterburn effect.

HIIT helps burn more calories in a shorter time by increasing your heart rate through intense bursts of exercise followed by rest. This method boosts your metabolism and leads to the afterburn effect, where your body continues to burn calories even after the workout. Learn more about this in our article on The after burn effect.

LISS is generally better for beginners because it is less intense and easier to maintain for longer periods, making it ideal for building endurance and establishing a fitness routine. HIIT can be more challenging but is effective for those who are already moderately fit and looking to maximize calorie burn in a shorter time.

Yes, combining LISS and HIIT in your workout routine can provide a balanced approach to fitness. This combination allows you to benefit from the endurance-building aspects of LISS and the calorie-burning efficiency of HIIT. Alternating between the two can prevent workout monotony and improve overall cardiovascular health.

For effective fat loss, a typical LISS session should last between 30 to 60 minutes. Research suggests that exercising at a steady pace for at least 45 minutes can effectively use fat as a source of energy, making it ideal for burning calories in a sustainable manner.

Examples of HIIT exercises include sprints, intervals on a stationary bike, battle ropes, burpees, mountain climbers, and jumping jacks. These exercises can be performed at maximum effort for short durations followed by rest periods, making them effective for high-intensity workouts.
