What is Interval Training
Interval training is training using short bursts of high intensity exercise that are separated by recovery periods of low intensity exercise. It alternates short bursts of intense activity with lower intensity activity. Interval training is a scientific way to train your body to burn more calories. You will push yourself beyond your comfort level for short bursts of time.
For example walk 3 mins then run for 1 min and keep doing that until your 45 mins or up. Gradually you'll be able to run for longer periods of time.This will force your body to burn more calories because when you do the running your body burns more energy. Giving your body this jolt will increase your overall calorie burning both during and after exercise. Interval training shocks your body and causes a greater increase in post exercise metabolism than regular cardio.
