  • LISS workouts are more time-consuming.   

HIIT vs LISS for Fat Loss – Which Is More Effective? 

HIIT and LISS are equally good for achieving your fat loss goal. During HIIT workouts, you experience bursts of exercise that stimulate your metabolism and increase your heart rate. Its combination of high intensity followed by low-intensity workout leads to extensive calorie burn after and during the work session. Hence, it proves to be highly effective in fat loss.  

The LISS workout also leads to fat loss, just at a slower rate. Due to its low-intensity exercises, LISS exercises can be practiced longer, making it almost as effective in fat loss as in a HIIT workout.  

In conclusion, go with a HIIT workout to improve your overall fitness level and stimulate fat loss faster in a shorter span. Opt for a LISS workout to burn your excess fat in a less straining way but over a longer period.   

Combining the two could make your fitness routine more balanced and exciting. For example, you can go with two sessions of HIIT workout and two sessions of LISS workout every week to achieve your desired fitness goal.
