Understanding HIIT: What Is an HIIT Workout?
The Basics of High-Intensity Interval Training
HIIT stands for High-Intensity Interval Training. It is a type of exercise that mixes short bursts of hard work with short rest periods. For example, you might run fast for 30 seconds, rest for 30 seconds, and repeat. HIIT workouts are usually short—often 10 to 30 minutes—but they are very effective.
How HIIT Differs from Other Cardio Workouts
Regular cardio, like jogging, uses steady effort for a longer time. HIIT makes you work much harder during the “go” times but lets you rest in between. This can help you burn more calories in less time and improve your fitness faster than steady cardio alone.

Metabolic and Cardiovascular Advantages
HIIT raises your metabolism. You’ll keep burning calories even after your workout. It also makes your heart stronger and helps lower blood pressure.
HIIT for Mental Health and Longevity
HIIT boosts mood and reduces stress. People who do HIIT regularly may live longer and have a lower risk of illnesses like diabetes and heart disease.
