How Long Is A HIIT Workout
High-Intensity Interval Training (HIIT) has become a popular form of exercise due to its efficiency and effectiveness. HIIT workouts typically involve short bursts of intense exercise followed by periods of rest or low-intensity activity.
The benefits of HIIT include improved cardiovascular health, increased metabolism, and fat loss. However, many people may wonder how long a HIIT workout should be to maximize these benefits.
In this article, we will explore the ideal length of a HIIT workout, the benefits of short and long HIIT workouts, and considerations for determining the appropriate length of a HIIT workout based on personal fitness goals, time availability, and other factors.
The Ideal HIIT Workout Length
The ideal length of a HIIT workout varies depending on several factors, including fitness level, goals, and the type of exercise performed during the workout. However, a general recommendation for HIIT workout duration is around 20 to 30 minutes, including warm-up and cool-down periods.
During a HIIT workout, individuals perform short, intense bursts of exercise followed by periods of rest or low-intensity activity. The length of each interval can vary but typically lasts between 20 and 60 seconds. The rest periods are typically longer than the exercise intervals and can last between 10 seconds and 2 minutes. The number of intervals performed during a HIIT workout can also vary but typically ranges from 4 to 10.
Factors that can affect the length of a HIIT workout include individual fitness levels, specific fitness goals, and the type of exercise performed. For example, a beginner may need to start with shorter intervals and longer rest periods, while someone more experienced may be able to perform longer intervals with shorter rest periods.

Some examples of different HIIT workout lengths include:
- 20-minute workout: 30 seconds of high-intensity exercise followed by 30 seconds of rest, repeated for 8 rounds.
- 30-minute workout: 45 seconds of high-intensity exercise followed by 15 seconds of rest, repeated for 10 rounds.
- 45-minute workout: 60 seconds of high-intensity exercise followed by 30 seconds of rest, repeated for 10 rounds.
Ultimately, the ideal length of a HIIT workout depends on personal fitness goals, time availability, and other factors. It’s important to find a balance between challenging yourself and avoiding injury or burnout.
Benefits of Short HIIT Workouts
Short HIIT workouts can be effective for several reasons. One of the main benefits of short HIIT workouts is that they are time-efficient, making them an excellent option for individuals with busy schedules who may struggle to find time to exercise. Short HIIT workouts can be completed in as little as 10-15 minutes, making them a convenient option for those who want to fit exercise into their daily routine.
Additionally, short HIIT workouts can be effective for increasing cardiovascular fitness, improving endurance, and burning calories. Research has shown that even short HIIT workouts can increase cardiovascular fitness and improve metabolic health. In fact, a study published in the journal Medicine and Science in Sports and Exercise found that just 10 minutes of high-intensity exercise can have similar benefits to longer, moderate-intensity workouts.
Short HIIT workouts can also be less intimidating for beginners or individuals who are new to exercise. The shorter workout duration can make it easier to get started with HIIT, which can help build confidence and motivation for longer workouts in the future.

Examples of short HIIT workouts include:
- Tabata: 20 seconds of high-intensity exercise followed by 10 seconds of rest, repeated for 4 minutes (8 rounds).
- The 7-Minute Workout: 12 exercises performed for 30 seconds each with 10 seconds of rest between exercises.
- 10-15 minute treadmill workout: 30 seconds of sprinting followed by 30 seconds of rest, repeated for 5-10 rounds.
Short HIIT workouts can be a time-efficient and effective way to improve cardiovascular fitness, burn calories, and increase endurance.
Benefits of Long HIIT Workouts
Long HIIT workouts can also provide a variety of benefits. One of the main benefits of longer HIIT workouts is that they can improve endurance and build stamina. By extending the duration of the workout and increasing the number of intervals, individuals can challenge their aerobic capacity and improve their overall endurance.
Long HIIT workouts can also be effective for increasing muscle strength and endurance. This is because HIIT workouts often involve bodyweight exercises or resistance training, which can help build muscle and improve muscular endurance over time. This can lead to improved physical performance in daily activities and other forms of exercise.
In addition, longer HIIT workouts can help individuals burn more calories and promote weight loss. HIIT workouts are known for their ability to increase the metabolism, and longer workouts can lead to a greater calorie burn both during and after the workout.
Research has shown that longer HIIT workouts can also have a positive impact on mental health. Exercise has been linked to improved mood, reduced stress levels, and increased feelings of wellbeing. By extending the duration of the workout, individuals can reap these benefits for a longer period of time.

Examples of longer HIIT workouts include:
- 45-minute HIIT workout: 60 seconds of high-intensity exercise followed by 30 seconds of rest, repeated for 15-20 rounds.
- 60-minute HIIT workout: 45 seconds of high-intensity exercise followed by 15 seconds of rest, repeated for 20-25 rounds.
- 90-minute HIIT workout: 90 seconds of high-intensity exercise followed by 30 seconds of rest, repeated for 30-40 rounds.
Longer HIIT workouts can be effective for improving endurance, building muscle strength, burning calories, and promoting mental health. However, it’s important to ensure that longer workouts are performed safely and are appropriate for individual fitness levels and goals.

Considerations for Determining HIIT Workout Length
When determining the length of a HIIT workout, there are several considerations to take into account. These include individual fitness level, specific goals, type of exercise performed, and available time.
Individual Fitness Level
HIIT workouts can be challenging, so it’s important to consider individual fitness level when determining workout length. Beginners may need to start with shorter intervals and longer rest periods, while more experienced individuals may be able to perform longer intervals with shorter rest periods.
Specific Goals
The length of a HIIT workout should also align with specific fitness goals. For example, if the goal is to improve cardiovascular fitness and endurance, longer workouts with more intervals may be necessary. Alternatively, if the goal is to focus on building muscle strength, shorter workouts with higher intensity intervals may be more effective.
Type of Exercise Performed
The type of exercise performed during a HIIT workout can also impact workout length. For example, exercises that involve weights or resistance training may require longer rest periods between intervals to allow for muscle recovery. Cardiovascular exercises, such as running or cycling, may require shorter rest periods to maintain a higher heart rate and intensity.
Available Time
Another consideration when determining the length of a HIIT workout is available time. Shorter HIIT workouts can be completed in as little as 10-15 minutes, making them a convenient option for individuals with busy schedules. Longer HIIT workouts may require more time and may not be feasible for everyone.
Ultimately, the ideal length of a HIIT workout will vary depending on individual factors and goals. It’s important to find a balance between challenging yourself and avoiding injury or burnout. Starting with shorter workouts and gradually increasing the length and intensity over time can be an effective way to build endurance and achieve fitness goals.
