HIIT vs. LISS: Which Cardio Workout Is Best for You?

When it comes to burning calories and improving cardiovascular health, there are two popular workout options to consider: HIIT (High-Intensity Interval Training) and LISS (Low-Intensity Steady State) cardio workouts. Both HIIT and LISS have their own unique benefits and can be effective for different fitness goals. In this article, we will explore the differences between these two workouts and help you determine which one is best suited for you.

HIIT: Break a Sweat in Less Time

HIIT involves short bursts of intense, high-energy exercises followed by periods of rest or low-intensity recovery. This workout is known for its ability to torch calories in a short amount of time. One of the main advantages of HIIT is that it elevates your heart rate and increases your metabolism during the workout and even long after the session ends.

Incorporating various bodyweight exercises, such as burpees, squats, and mountain climbers, HIIT workouts are designed to push your limits and maximize your effort. The intervals of intense exercise push your cardiovascular system to work harder, leading to improved endurance and increased cardiovascular capacity over time.

HIIT is particularly beneficial for those with busy schedules who want to maximize their workout efficiency without spending hours at the gym. A typical HIIT session can last anywhere from 15 to 30 minutes, making it ideal for individuals with limited time but still seeking significant results.

LISS: Steady and Sustainable

Unlike HIIT, LISS involves maintaining a steady, moderate-intensity level of exercise for an extended period. Walking, jogging, and cycling are excellent options for LISS workouts, as they are low-impact and can be sustained for longer durations.

LISS workouts aim to keep your heart rate within a specific target zone, typically around 40-60% of your maximum heart rate. This intensity allows your body to tap into its fat stores, making LISS an effective option for individuals looking to improve their overall endurance and promote fat loss.

LISS workouts are great for beginners who are just starting to incorporate regular exercise into their lifestyle. Additionally, LISS can also serve as a rest day option for individuals who are already following a more intense workout routine. It provides an opportunity to engage in physical activity without placing excessive stress on the body, promoting recovery and active rest days.

Which One Should You Choose?

Deciding between HIIT and LISS ultimately depends on your fitness goals, preferences, and current fitness level. Here are some factors to consider:

1. Time:

If you have limited time and want to maximize calorie burn and cardiovascular benefits within a short duration, HIIT may be the better choice. On the other hand, if you enjoy longer workouts or have time for steady-state cardio, LISS can be a great option.

2. Fitness Level:

HIIT is generally more challenging and intense, making it suitable for individuals who are already active or have a higher fitness level. While LISS is accessible to individuals at any fitness level, it may be a more reasonable starting point for beginners or those with limited mobility.

3. Variety:

If you prefer a great variety of exercises and enjoy mixing things up during your workout sessions, HIIT’s constantly changing routines may be more appealing. However, if you find comfort in a consistent pace and enjoy activities like long walks or leisurely cycling, LISS might be the perfect fit.

4. Joint Impact:

Consider the impact on your joints. HIIT exercises involve high-intensity movements that can put pressure on joints, ligaments, and tendons. In contrast, LISS workouts are low-impact and place less stress on your body, allowing for joint-friendly exercise.


Both HIIT and LISS offer numerous benefits and can be effective ways to improve cardiovascular health and burn calories. The choice between HIIT and LISS depends on your specific fitness goals, preferences, and overall health. If you’re looking for a time-efficient workout that can challenge you and elevate your fitness, HIIT might be your best bet. However, if you prefer a steady and sustainable routine that is gentle on your joints or if you’re just starting out, LISS could be the perfect fit. Ultimately, it is important to listen to your body and choose the workout style that aligns with your needs and allows you to maintain consistency in your fitness journey.
