HIIT or High-Intensity Interval Training is a workout style that alternates rests and intervals of intense workout. The purpose of this training to push yourself with a short burst of high intensity training and rest or relax with a little bit of low intensity exercise. HIIT can provide a lot of benefits for the users such as:

1. Benefits to your heart

HIIT helps with strengthening the heart muscle and make improvements to your cardiovascular system. The short burst of exercise often boosts your heart rate which helps with oxygen production and consumption.

2. Boost metabolic function

HIIT improves the function of the mitochondria, the energy powerhouse of the cell which is responsible for energy production and regulating cellular metabolism.

3. Build muscle

Studies have shown that HIIT can increase fat-free mass like muscles by 1% to 3%. This proves beneficial for elderly people who lose muscle at an increased rate due to aging.

4. Preserve muscle power

HIIT is able to help with fast-twitch muscle fibers which are responsible for making sudden movements. This becomes even more important as these fibers gradually degrade as you age and making these types of movement becomes more and more difficult as time goes on.

Getting started with HIIT is very easy and manageable, even for an elderly adult. The key is to make minor adjustments to what you’re already doing with your exercise. For instance, if you normally walk for 30mns, then try walking as fast as you can for 1-3mns and returns to your normal or slower pace for 1-3mns before doing it all over again.
