HIIT exercise is a trend that has been sweeping the nation for a while now. But what exactly is it? HIIT stands for High-Intensity Interval Training. It is centered around short bursts of exercise that are split with a shorter period of rest allowing you to give 90-100% effort in short bursts.

You don't need to be super fit to do it as it can be tailored for all levels.

- For all levels – want to push yourself go for 40 seconds exercise with 20 seconds rest. New to HIIT? Go for 20 seconds exercise with 10 seconds rest and build up to 30 seconds exercise with 15 seconds rest.

- Fits around your schedule – if you only have 15 minutes to spare, just do 15 minutes

- You don’t need any equipment – of course, you can do HIIT on an exercise bike or rower, but if you haven’t got access to these, just you and a small area will do.

- Feel the burn - HIIT is said to burn fat for hours after you’ve completed the exercise due to an increase in metabolic rate
