Calorie Burn: HIIT burns more calories in a shorter amount of time compared to walking, leading to faster fat loss, including belly fat.
Afterburn Effect: HIIT triggers the afterburn effect (EPOC), meaning your body continues to burn calories at an elevated rate even after the workout, aiding in faster fat loss.
Fat Loss Efficiency: While walking is lower intensity, it’s still effective for fat burning, especially when done consistently over time, though not as quickly as HIIT.
Sustainability: Walking is easier on the joints and can be done daily for longer durations, making it a more sustainable long-term fat-burning exercise compared to the intense nature of HIIT.
Muscle Building: HIIT often incorporates bodyweight exercises or strength training, which helps build muscle while burning fat, potentially leading to more noticeable belly fat reduction.
Intensity and Duration: HIIT is short but intense, often lasting 20-30 minutes, while walking requires longer durations (30-60 minutes) to achieve similar fat-burning results.
Hormonal Impact: HIIT boosts growth hormone production and increases fat oxidation, promoting quicker belly fat loss compared to walking.
Accessibility: Walking is easier to start, requires no special equipment, and can be done anywhere, making it an accessible option for many, while HIIT may require some fitness experience.
