What is HIIT?

HIIT, or ‘high intensity interval training’ is a form of training based around short periods of intense exercise, followed by a brief rest time before repeating the process.

On a treadmill, your HIIT workouts will most likely take the form of interval sprints. This means maxing out at top speed for any time between 20-60 seconds. You’ll then slow to a walk or stop completely to recover for 30-90 seconds. This is usually repeated around 10 times and takes about 20 minutes to complete.

This type of training allows you to exert maximum effort, which creates a powerful fat burning reaction within your body.

By pushing yourself as hard as you can, your body moves into an anaerobic zone for a short period of time. When your body is working this hard, it releases certain hormones that triggers higher fat oxidization levels [1].

This basically means your body can recruit fat as fuel more easily, which results in targeting the cells you really want to get rid of.

On top of that you’ll also continue to burn fat for around 24 hours after you finish the workout. This is called excess post-exercise oxygen consumption or EPOC [2]. Achieving this state keeps your body burning extra calories, way after you’re done working out.

Research has also shown that exercising in this way three times a week for 12 weeks resulted in a weight loss of 1.5kg and a total fat loss of 2kg [3], which shows HIIT can help to support muscle development, whilst cutting down on fat.

To round it all up, HIIT is one of the most effective ways to turn the heat up on your fat loss. It targets fat specifically, keeps you burning calories for hours after you finish your session and even helps to maintain muscle, which is key to creating a higher metabolism.
