If you don’t want to spend a large portion of your time exercising, a high-intensity interval training program may be for you. You will get to feel and see great physical and health benefits but while only working out for 20 to 30 minutes 2 to 3 times a week. HIIT will improve your endurance and increase your metabolism helping with caloric expenditure, fat burn and weight loss. HIIT also helps improve or prevent high blood pressure, blood sugar, insulin resistance and heart health. This program can be done with or without equipment, anywhere and at any time, making it a very effective workout.
