What is HIIT and how is it different from Interval Training
Interval training is very similar to HIIT training - only the intensity is different. High intensity interval training lasting 20 minutes or less where as interval training can last longer. Both interval and HIIT training focuses on exercises that use major muscle groups, compound movement and high intensity training . Interval and HIIT tap the energy sources inside the muscle .
The reason that High Intensity Interval Training works better for fat loss is this: When you do a cardio session at the same pace the whole time, your body goes into what is called steady state. This means that your body has adjusted itself to the speed you are going and tries hard to conserve energy (calories). You will be able to avoid this and burn more calories and FAT by doing the interval training.
