Exercise is the key to healthy body. Everybody knows it but still they compromise on this fact. The result is – 60 percent people in America are overweight. Millions of people are suffering from Hypertension/high blood pressure, diabetes, cholesterol. Hospitals are full. Everybody is trying to find the solution in medicines but it has its own limitations.

Exercise is the cheapest way to improve upon various ailments, without any side effects. General excuse is non-availability of time.

Are you aware that INTERVAL TRAINING – newest exercise research is showing that you can cut your workout time significantly and reap even better benefits?

You break your exercise session into short segments that alternate high intensity with a rest period in-between. It can dramatically improve your cardiovascular fitness and fat-burning capabilities in a fraction of the time.

Take this latest study, in which men pedalled on a stationary bike for 20 minutes using interval training (they pedalled at the highest intensity they could for a minute, then pedalled slowly to rest for a minute, and so on for the 20-minute period). These men received the same benefits as they would have had they exercised at a lower intensity for one hour or more, leading researchers to say interval training “may represent an alternative to endurance training to improve metabolic health and reduce the risk for chronic diseases.”

Several studies have confirmed that exercising in shorter bursts with rest periods in between burns more fat than exercising continuously for an entire session. This has been shown to hold true even when the session is not done at an extremely high intensity.

In one such study, those who cycled for 40 minutes, alternating four-minute bursts at 90 percent effort with two minutes of rest, improved their cardiovascular fitness by 13 percent, and were able to burn 36 percent more fat during a later hour-long moderate cycling session.

Another study took it even further, showing you can burn more fat exercising for 20 minutes than for 40 minutes!

In their trial, women either exercised for 20 minutes, alternating 8 seconds of sprinting on a bike with 12 seconds of exercising lightly, or exercised at a regular pace for 40 minutes. After exercising three times a week for 15 weeks, those who did the 20-minute, alternating routine lost three times as much fat as the other women.

The researchers believe this type of exercise works because it produces a unique metabolic response. Intermittent sprinting produces high levels of chemical compounds called catecholamine, which allow more fat to be burned from under your skin and within your muscles. The resulting increase in fat oxidation is thought to drive the increased weight loss.

Again, one of the best parts of interval training is that it cuts down on the amount of time you need to exercise, which is great if you don’t have time for hour-long cardio workouts.
