The idea that high-intensity interval training (HIIT) — aka “burst training” — is one of the best ways to burn fat, tone muscle, and get fit fast is nothing new. Many of the world’s top fitness experts have been recommending it since at least the early 90’s. A significant amount of scientific research has proven its effectiveness in recent years, showing that it can help you achieve better fitness in less time than conventional cardio workouts.
Simply put, interval-based workouts involving short bursts of very intense exercise burn calories and body fat efficiently while dramatically improving cardiovascular health at the same time. Oh and it does all this without almost any of the negative consequences involved in typical “long, slow” aerobic exercise.
