HIIT or High Intensity Interval Training has been linked to improved metabolism, cardiovascular fitness, muscle growth and increased fat burning. Many studies that have been conducted in recent times support the theory that High Intensity Interval Training in short training sessions (approximately 15 mins) burns more calories than jogging on a treadmill for an hour. Aztec Fitness recommend enjoying 2-3 HIIT sessions per week. I’m a big believer in working smarter, not harder but, you must use good exercise techniques to ensure quality muscle development and injury prevention. So, would you rather jog on a treadmill for 60 mins or do short High Intensity Interval Workouts with Aztec Fitness?
