What Is High Intensity Interval Training?

High Intensity interval training is a dynamic way to get the most out of your workout.  It is effective if you are trying to build strength increase endurance and lose weight.  

It is like a cardio session but instead you go all out for 30, 60 or 90 second intervals.  You push yourself to the max of each set which creates short bursts of very hard work; functioning at around 80-95% of your estimated maximum heart rate which is then followed by a break.

A class generally combines cardio and strength training to create a well-rounded high intensity workout.  It is also an effective way to build and recruit fast twitch muscle, burn calories in a short amount of time and increase the metabolism.

Therefore high intensity interval training can be a powerful way to work out and see the body composition and fitness results you want within a short space of time.  The principle is very simple; increased effort = higher oxygen intake = larger calorie burn.  Which in turn burns more calories during and after your workout.

Classes are timed in an interval format, which typically lasts  20 – 45 minutes.

Is High Intensity Interval Training For You?

Just because this type of workout states that it is high intensity, you should not be put off by the name.  You may feel that it is not for you because you are not fit enough or have not done this type of training before, but this is not the case. 

Because you work towards your own all out effort, you are able to pace yourself accordingly.  Everybody’s fitness levels are different and each and every person in the class will be working at there own pace.  So this kind of training is suitable for anyone.

High intenstiy interval training can be performed using a variety of exercises such as strength exercises, bodyweight exercises, rowing, walking, cycling, swimming, or running or group fitness classes. 

Workouts can also be modified for people  people with various medical conditions including people with diabetes or being overweight.  Also, exercises within the session can be modified if you have previous injuries or need to work on increasing stength and or mobility.


Don’t be put off by what the class is called.  If you want to get fit and get shredded quick then this is a great way to do it.

Just remember to listen to your body and do what you can within your ability.  Do not try to push yourself too far because other people are lasting longer or performing at a higher intensity than you.  Increasing endurance and fitness levels take time and it is best to work out in a safe and controlled manner to reduce the risk of injury.
