High-intensity interval training, commonly known as HIIT, is a type of exercise that involves short bursts of intense activity followed by brief periods of rest. HIIT has become increasingly popular due to its numerous benefits, including improved cardiovascular health, increased fat burning, and improved athletic performance.
In this article, we will explore the benefits of HIIT and provide some tips on how to get started with high-intensity interval training.
Benefits of High-Intensity Interval Training (HIIT)
If you want to get fit and improve your body composition, then high-intensity interval training, or HIIT, is a great option. Not only is HIIT a time-efficient way to work out, but it also provides numerous health benefits.
During a HIIT workout, you push your body to work at a high intensity for short periods, followed by periods of rest or low-intensity activity. This training method can help you burn more calories and build muscle, improving body composition.
In addition, HIIT has been shown to improve cardiovascular fitness, increase endurance, and reduce the risk of chronic diseases. Here are more details about the benefits of HIIT workouts.
HIIT and Cardiovascular Health
One of the key benefits of HIIT is that it can improve cardiovascular health.
Research shows that high-intensity exercise has been shown to increase heart rate quicker than lower-intensity exercise, which can help to strengthen the heart and improve its ability to function effectively.
The strenuous effects of HIIT appear safe when HIIT workouts are conducted properly, and HIIT can reduce the risk of heart disease, stroke, and other health conditions associated with poor cardiovascular health.
HIIT for Body Composition
Research also indicates that HIIT can be an effective way to burn fat and lose weight. During high-intensity exercise, the body uses more oxygen, which can increase the production of hormones that help break down fat.
This can lead to increased fat-burning and weight loss, even after the workout.
In addition, HIIT is more effective at burning fat than other types of exercise, such as steady-state cardio.
HIIT workouts are more effective than steady-state cardio for improving body composition because they burn more calories and can help increase muscle mass.
HIIT workouts raise your heart rate higher than steady-state cardio workouts. This increased effort can help you burn more calories during and after your workout, as your body continues to burn calories at an elevated rate for several hours after you finish exercising.
In addition to burning more calories, HIIT can also help you build muscle. When you engage in intense exercise like HIIT workouts, your body breaks down muscle fibers, which require repair, leading to increased muscle mass.
In contrast, steady-state cardio does not provide the same stimulus to your muscles, making it less effective at increasing muscle mass.
HIIT is a more effective way to improve body composition because it burns more calories and can help build muscle.
HIIT Workouts for Athletic Performance
Another benefit of HIIT is that it can improve athletic performance.
High-intensity interval training can increase the body’s ability to use oxygen, which is essential for endurance activities such as running, cycling, and swimming.
HIIT workouts can also improve the body’s ability to produce energy quickly, which is important for activities that require short bursts of intense efforts, such as sprinting or jumping.
As a result, HIIT can help athletes perform better in their chosen sports, which is why many professional athletes frequently do HIIT workouts.
HIIT Workouts Save Time
HIIT workouts are time-efficient because it allows you to get a challenging workout in a short amount of time.
Unlike steady-state cardio, which involves exercising consistently for an extended period, HIIT involves alternating between intense bursts of activity and periods of rest.
Properly designed HIIT workouts can be completed in as little as 15-20 minutes, making them a great option for busy individuals who want a quick and effective workout.
Metabolic Conditioning vs. HIIT
Metabolic Conditioning (MetCon) workouts and High-Intensity Interval Training (HIIT) are both high-intensity workout styles that aim to improve the body’s energy pathways, burn calories, and enhance overall fitness.
However, there are some differences between the two.
Metabolic Conditioning is a broad term that can encompass a variety of workouts that use exercises to improve the body’s immediate, intermediate, and long-term energy pathways.
Metabolic Conditioning workouts can take different forms, such as circuits, spin classes, and Tabata workouts, and are typically done at a high intensity for longer periods, usually 10 minutes or more.
The goal is to condition the body to become more efficient in using energy.
In contrast, HIIT workouts are more narrowly defined and are done at the highest energy level possible with predetermined rest intervals throughout.
HIIT workouts can be circuits or MetCons, but they typically involve short bursts of intense exercise followed by brief rest or recovery periods.
HIIT workouts are designed to maximize the body’s calorie burn, even after the workout is over, and to improve aerobic capacity.
Both Metabolic Conditioning and HIIT workouts offer significant health benefits.
MetCon improves the body’s efficiency in using energy, burns calories, increases aerobic capacity, and can help build lean muscle mass and reduce body fat.
HIIT workouts also burn calories, increase aerobic capacity, and can help build lean muscle mass, but they are more specifically focused on calorie burn and improving the body’s ability to recover from intense exercise.
MetCon and HIIT are both effective high-intensity workout styles that offer significant health benefits.
While there are some differences, both can be useful for improving overall fitness, burning calories, and building lean muscle mass.
How to Get Started with HIIT Workouts
So, how do you get started with HIIT?
The first step is to consult your doctor, especially if you have any pre-existing health conditions or are new to exercise.
Once you have the go-ahead from your doctor, you can begin by incorporating short bursts of intense exercise into your workout routine.
Start by warming up with light cardiovascular exercises, such as jogging or cycling, for 5-10 minutes. This will help prepare your body for the intense workout to come.
Choose a type of exercise you enjoy that is appropriate for your fitness level. Some common options for HIIT include running, cycling, jumping jacks, burpees, and mountain climbers.
Begin with a brief period of intense exercise, such as 30 seconds of sprinting or 30 seconds of jumping jacks. Push yourself to work as hard as you can during this period.
Follow the intense exercise with a rest period, such as 30-60 seconds of walking or jogging. This rest period will allow your body to recover before the next intense interval.
Repeat the intense exercise and rest intervals several times, depending on your fitness level and the available time.
A typical HIIT workout might include 8-10 intervals of intense exercise, with equal periods of rest in between.
Finish your workout with a cool-down period of light cardiovascular exercise and stretching to help your body recover and prevent injury.
The Best HIIT Workout Program (2023)
In my opinion, the best HIIT workout program is the Tabata interval protocol.
The Tabata interval protocol is a high-intensity interval training workout that involves working at maximum intensity for 20 seconds, followed by 10 seconds of rest, which was developed by Dr. Izumi Tabata and his colleagues at the National Institute of Fitness and Sports in Japan.
You can do the Tabata interval protocol with a variety of different exercises. Here are some good options:
- Jumping jacks
- Mountain climbers
- Squat jumps
- Plank jacks
- Jumping lunges
- Box jumps
- Kettlebell swings
Additionally, you can use cardio machines, like the stationary bike or ERG rowing machine.
You do one exercise for the entirety of the workout, or you can include multiple different exercises.
Concluding Thoughts – HIIT Workouts Benefits
It’s important to listen to your body and not push yourself too hard when starting with HIIT.
If you are new to this type of training, you may want to start with shorter intervals of intense exercise and longer periods of rest while gradually increasing the intensity and duration of the intervals as you become fitter.
It’s also a good idea to consult a doctor or personal trainer before starting any new workout routine.
