 One of the greatest barriers to daily exercise is a perceived lack of time. For those who wish to participate in some kind of physical activity but find themselves time challenged, high intensity interval training or HIIT may be the perfect time efficient solution. HIIT is a combination of very brief, very high intensity activity, followed by equal or longer recovery periods. A few HIIT exercises include walk and sprint, infinite push-ups, infinite squats, sprinting up or down the stairs, or a combination of exercises put together. Regardless of the exercise, the method is the same. Short spurts a vigorous exercise followed by recovery. Do this 5 to 30 minutes, 2 to 3 times per week and you're on your way to better health. The benefits you can expect from HIIT include helps burn fat while retaining an increasing lean muscle mass, strengthens the cardiovascular system, helps develop sport-specific energy systems, and reduce heart rate and blood pressure and overweight and obese individuals. For those who have given up on exercise or who never started because of time restraints, try using high intensity interval training or HIIT. HIIT's good health is only 10 minutes away.
