Best heart rate to burn fat

Best heart rate to burn fat - Fitness Health
What's the best heart to burn fat?

Since the early seventies, heart rate monitors have been used to monitor our exercise levels and give us an accurate measurement of our body workout intensity. Over this time many people have used heart rate exercise charts for guidance on fat calorie burning. These are simple graphs that show the output of our heart rate levels. The graph gives you an easy guide to show what you increase when conducting cardio exercises as you can see the different heart rates for aerobic vs fat burning heart rate intensity levels.

On a brief view. The chart quickly shows us the best heart rate we need to exercise in order to burn more fat. Since using the exercise zone chart for guidance, we've learned that our best heart rate for burning fat is the fat burning zone  65 - 70% of your maximum heart rate (MHR). In the heart rate chart,it states that we need to exercise for 30 minutes continuously at the heart rate zone of 60%-70% in order to burn fat more efficiently.

This zone is the guideline for all exercisers of all ages but isn't 100% accurate. If you wish to have a more personalised approach here's the formula for working out your own personal fat-burning zone.

In order to burn more fat, you first need to identify your correct heart rate fat burning level. Working out the best heart rate to lose weight, Please follow these steps below to work out the calculation. You will need a calculator to complete these steps.

Step 1 

First minus your age from 220

  • 220 - your age = MHR

Example, Matt is 33 years old, he needs to work out his personal MHR (maximum heart rate)

Matt's Example

220 - 33 = 187 MHR =  100% maximum heart rate is 187

Step 2

Once we have the personal MHR (maximum heart rate), we then have to make calculations for heart rate exercise percentage. This way; 

  • 90% = Your MHR x 0.9 = 90% your personal exercise heart rate
  • 60% = Your MHR x 0.6 = 60% your personal exercise heart rate

Matt's Example 

  • 90% MHR= 187 x 0.9 = 168 - 90% Matt's personal exercise heart rate
  • 65% MHR= 187 x 0.65 = 122 - 65% Matt's personal exercise heart rate

Now you have your personalised percentages.

Most trainers advise that in order to burn fat you should complete cardio training exercise (i.e running, cycling)  for minutes between 65% and 75% of your MHR. Why? will this improve the calories burned ?

Recent research on effective fat burning shows that people who exercise with high-intensity intervals (HIIT) for a shorter period of time are three times more successful at burning fat than normal cardio exercisers that use a fat burning zone chart as a guideline.

On average thirty percent more calories are burnt with high-intensity interval training (HIIT)

 These studies found that a group of men that completed twenty weeks of interval training, lost nine times more fat than that from men who exercise regularly between the fat-burning zone 65-70%. 

Between 60-70% maximum heart rate, is not enough! A fitness professional would tell you if you want to burn fat then you need to get wet, often training between the 60%-70% workout zones puts you into a world of ease, making it easier for you to fall short of your target distance and finish early.

Interval training 

If you train in the gym then most of the cardio machines will have a pre-set button for interval training.

If your training outside then the best way is by using a heart rate monitor, this is easier and more personal, you can be sure to reach the correct levels for your fat-burning workout. This will give you an more accurate best hr for fat burning.

Interval training, with a heart rate monitor

First, complete the workings your personal MHR  with the steps shown above. Make the following calculations and write these down.

  • 75 % MHR =
  • 80% MHR =
  • 85% MHR =

Once you have these calculations you can start. Make sure you warm-up and cool down before sessions. 

Example Sessions running 

  • 1st  Session - 75% 2 minutes - 80%  2minutes - 85% 2 minutes - 80% 2 minutes - 85%- 1 minute - 75% 5 minutes.
  • 2nd Session -  75% 3 minutes - 80%  3 minutes - 85% 2 minutes - 80% 3 minutes - 85%- 1 minute - 75% 5 minutes.
  • 3rd Session-  75% 2 minutes - 85%  2 minutes - 75% 2 minutes - 85% 2 minutes - 75%- 2 minute - 85% 2 minutes.

You need to adjust the training to your fitness. If it's too easy to complete the session then you will need to complete this routine twice or increase the time. The most important base for HIIT training is that you keep changing the levels constantly. Every session should be different.

Interval training without heart rate monitor 

When I train using interval training, I often use trees to measure my distance. I normally sprint from one tree to another, then walk back to my starting place. I would normally repeat this five times, 

The first sprint run at 80% intensity 

The second sprint run 85% intensity

The third and fourth 95% intensity

Then Fifth 80% intensity

 The distance is normally 50 to 100 meters from tree to tree.

Another way to do this is by using a watch, set an alarm to activate every 45 seconds then follow this method.

  • 45 seconds 65 % sprint
  • 45 seconds 85% sprint
  • rest 1 minute Walk
  • Repeat x 8
