Whether you are fed up of doing long boring cardios week after week, want to accelerate the weight loss process by a big margin, or simply wish to spend less time on exercises, you got to do interval training. Basically, with interval training, you alternate between workouts of low and high intensity. Now, what is so interesting about interval training? Interval training has so many pros that I don't know where to start. Following are the main advantages of interval training: a) Since you alternate between different types of workouts, you would hardly become bored of your exercise routine, ever. b) When you do the same workout day after day, your body soon adjusts your metabolic rate accordingly, so that you stop burning fat after a point of time. However, in case of interval training, since you are alternating between high intensity and low intensity workouts, your body would always keep your metabolism high, which in turn would help you burn fat fast. c) Interval training is a huge time saver since you don't need to spend more than 15-30 minutes per day on your workouts. No wonder almost all busy professionals and celebrities are addicted to it. d) Unlike cardios, interval training not only helps you burn fat during the workout session itself but even when you are resting. This means that whether you are watching a movie, playing chess, or enjoying video games, you would continue to burn fat effortlessly. Now isn't that really sweet - being able to burn fat the "lazy" way? e) It doesn't exhaust you: If you have ever tried to walk along a steep mountain or even a small hill, you would know how exhaustive it can be. Similarly, if you run along a steep surface, you would become fatigued very soon. In contrast, if you walk up and down a hill, you wouldn't feel tired. Why? While your body is fatigued at the time you are walking along the steep surface, it starts recovering from the exhaustion as you climb downwards. That is interval training for you. Quite similarly, running along a flat surface would be less tiring for you than running across a steep surface, even though you would burn almost the same amount of calories either way. Therefore, be sure to add interval training to your current workout routine. If you are a fan of aerobics, you could make your case better by adding sprints and jumps to your aerobic exercises. If treadmill workout is what you like to do, you can do it by upping the incline of the treadmill a notch higher at regular intervals. On the other hand, if you prefer walking, you should alternate between slow and fast walking.
