The Ultimate Guide to High-Intensity Interval Training In fitness education, high-intensity interval training, commonly referred to as HIIT, has emerged as a versatile form of the HIIT workout is characterized by brief bursts of alternating intensity exercise with minimal recovery periods.
This method not only optimizes calorie burn, but also improves overall cardiovascular health and fitness. Let’s delve into the technicalities, benefits and best practices of HIIT. HIIT HIIT logic involves repeated intense effort followed by periods of recovery. For example, a typical HIIT workout might consist of 30 seconds of jogging followed by 30 seconds of walking or rest.
This cycle is repeated for 15-30 minutes, making HIIT a time-saving workout. During periods of high intensity, the intensity level should be at 80-95% of your maximum heart rate, pushing your body close to its limits.
The Science Behind HIIT The effectiveness of HIIT lies in its effects on metabolism. Intensive intervals push the body into an anaerobic state, where it burns glycogen stored in the muscles for energy.
During the recovery phase, the body switches back to aerobic metabolism.
This constant shifting of energy systems increases metabolism, increasing calorie burn even post-exercise, known as the Afterburn Effect or Excess Post-Exercise Oxygen Consumption ( EPOC) HIIT Benefits of Efficient Calorie Burning:
HIIT compared to traditional steady state cardio Enables you to burn more calories. Studies have shown that 15 minutes of HIIT can burn as many calories as an hour of jogging. Improved cardiovascular health:
HIIT significantly increases cardiovascular endurance and heart
