We have all used the excuse that we have no time to train, but with High Intensity Interval Training yes you do! Allowing you to burn more calories and have a high cardiovascular workout in a short amount of time.HIIT training is so effective as a fat burner as it produces excess post-oxygen consumption, meaning that even when you stop training you continue to burn calories!If you are new to interval training then start off with one or two sessions a week letting your body recover fully in between, avoiding over training.The most well-known form of interval training is Tabata. This includes 8 rounds of 20 seconds as hard as you can with 10 seconds rest in between each set. This is said to have the same benefits to the aerobic system as a 60 minute steady run or cycle, but this alone doesn’t make for a well-rounded fitness routine, so use intervals alongside the routines you already know and love. Circuit training is also a fantastic form of interval training with the boom of boot camps and indoor classes everywhere there’s no excuses not to put yourself through your paces.If you train with intervals already, try wearing a weighted vest while running or lifting to boost the effectiveness of your intervals or sprint UP that hill you would normally run down!
