Have you been doing the same old slow cardio for weeks, or years (eek!) on end? Do you ever wonder how can it be that you can run six miles straight and still haven’t seen the scale budge more than a pound or two? That’s because you’re not working out at a high enough intensity! I am not suggesting that you start running those six miles faster, I am saying that it’s time you switched over to High Intensity Interval Training, called HIIT.
HIIT training has been proven to burn more fat in less time comparedto long, slower cardio sessions. In fact, if done correctly you HIIT session shouldn’t last longer than 20-30 minutes (trust me you will be spent!) So how do you do this you ask? Simple, you alternate between high intensity and low intensity. 
Begin with a 5 minute warm up. Perform an intensity blast for one minute and then recover for two minutes. Repeat cycle of high intensity and low intensity for 5-8 rounds. Cool down for 5 minutes and stretching of major muscle groups.
Intensity blasts can be performed by increasing the resistance on a machine, increasing the incline, or by sprinting. Replace your traditional cardio workouts with HIIT training 3 times a week and you will start to see results within the month! Please be aware that if you are severely deconditioned I do not recommend that you start with a program of this intensity.
If you have never tried HIIT training, give it a try and let me know how you feel afterwards!
