The Connection Between Mental Health, Personal Care, and Weight Loss

The Science of HIIT

HIIT involves alternating between short periods of intense exercise and periods of lower intensity or rest. This approach works by pushing your body to its limits during the high-intensity intervals, followed by recovery periods that allow you to partially recover. Here’s a closer look at how HIIT affects your body:

Increased Oxygen Consumption

During high-intensity intervals, your body consumes more oxygen to meet the increased energy demands. This heightened oxygen consumption leads to a greater calorie burn both during and after the workout. This phenomenon is known as excess post-exercise oxygen consumption (EPOC), which contributes to continued calorie burning even after the workout ends.

Additionally, the combination of aerobic and anaerobic exercise during HIIT enhances your body’s ability to utilize stored fat as a source of energy.

Improved Cardiovascular Health

Research has shown that HIIT can significantly improve cardiovascular health by increasing heart rate and improving blood circulation. HIIT workouts enhance the efficiency of the heart and lungs, leading to improved cardiovascular fitness and reduced risk of heart disease.
