You may have heard of HIIT training though didn’t really know what the health benefits of it are, what it involves or if you should even do it. We want to help you understand HIIT training exercise.
HIIT stands for High-Intensity Interval Training. It is a popular and effective exercise method that involves alternating between short bursts of intense physical activity and brief periods of rest or lower-intensity exercise. The primary goal of HIIT is to maximize the benefits of a workout in a shorter amount of time compared to traditional steady-state cardio workouts.
Here’s how HIIT typically works:
Warm-up: Begin with a short warm-up period to prepare your body for the upcoming intense intervals. This can include light jogging, jumping jacks, or dynamic stretches.
Intervals: Perform a high-intensity exercise or activity (e.g., sprinting, cycling at maximum effort, burpees, jumping rope) for a short duration, usually ranging from 20 seconds to 60 seconds. The intensity should be close to your maximum capacity, making it challenging.
Recovery: After the intense interval, take a short period of rest or engage in a lower-intensity exercise (e.g., walking, slow cycling) for a brief duration, typically ranging from 10 seconds to 60 seconds. This allows your heart rate to come down and provides a brief recovery before the next intense interval.
Repeat: Alternate between the high-intensity intervals and recovery periods for a set number of cycles or a predetermined amount of time. A typical HIIT workout might consist of 4 to 10 cycles, depending on your fitness level and goals.
Cool-down: After completing the HIIT intervals, cool down with some gentle stretching and deep breathing exercises to gradually lower your heart rate and prevent muscle soreness.
The key benefits of HIIT training include:
Efficiency: HIIT workouts are time-efficient, making them ideal for people with busy schedules.
Cardiovascular Health: HIIT can improve cardiovascular fitness, lower blood pressure, and enhance heart health.
Fat Burning: HIIT is effective for burning calories and promoting fat loss, both during and after the workout (due to the “afterburn” effect or excess post-exercise oxygen consumption, EPOC).
Muscle Endurance: It can help improve muscular endurance and stamina.
Metabolic Benefits: HIIT may enhance metabolic rate and insulin sensitivity.
Variety: There are numerous exercises and combinations that can be used in HIIT, allowing for variety and preventing workout boredom.
HIIT can be adapted to various fitness levels, from beginners to advanced athletes, by adjusting the intensity and duration of intervals and rest periods. However, it’s essential to start at an appropriate level for your fitness and gradually increase the intensity as your endurance improves. HIIT is known for its intensity, so it’s crucial to pay attention to proper form and safety to avoid injury. If you’re new to exercise or have underlying health conditions, it’s a good idea to consult with a fitness professional or healthcare provider before starting a HIIT program.
HIIT TRAINING ORIGINS
High-Intensity Interval Training (HIIT) as a structured fitness concept didn’t originate from a specific individual or location. Instead, it evolved over time as a result of various exercise and sports training methods. HIIT draws on principles from different training practices and has its roots in a variety of disciplines. Here’s a brief overview of the evolution and influences of HIIT:
Fartlek Training (1930s): The concept of varying running speeds to improve performance dates back to the 1930s when Swedish coach Gösta Holmér developed “fartlek” training, which means “speed play” in Swedish. This training method involved alternating between fast and slow running to build both aerobic and anaerobic endurance.
Tabata Protocol (1990s): One of the earliest formalized HIIT protocols is often attributed to Dr. Izumi Tabata, a Japanese researcher. In the 1990s, Tabata and his team conducted a study that involved 20 seconds of all-out effort followed by 10 seconds of rest, repeated for a total of four minutes. This specific protocol gained attention for its efficiency in improving both aerobic and anaerobic fitness.
Interval Training in Athletics: Interval training has long been used in sports like track and field, swimming, and cycling to enhance athletes’ speed, power, and endurance. Coaches and trainers in various sports have used interval training as a cornerstone of their athletes’ conditioning programs.
Military Training: Some aspects of HIIT have also been incorporated into military fitness training programs, where the emphasis is on improving physical readiness, strength, and stamina.
General Fitness and Commercialization: HIIT gained popularity in the fitness industry as trainers and fitness enthusiasts recognized its effectiveness for general fitness, fat loss, and cardiovascular health. Gyms and fitness studios began offering HIIT classes and programs.
While High-Intensity Interval Training (HIIT) is not directly rooted in bodybuilding, there is some overlap between the two in terms of training principles and goals. Bodybuilding and HIIT are distinct fitness disciplines, but certain aspects of HIIT may be incorporated into a bodybuilder’s training regimen for specific purposes. Here’s how they relate:
Fat Loss: Bodybuilders often use HIIT as a tool for fat loss during their cutting phases, leading up to competitions. HIIT can help shed excess body fat and improve muscle definition due to its calorie-burning effects and the afterburn (EPOC) that occurs after high-intensity workouts.
Cardiovascular Conditioning: HIIT can be used by bodybuilders to improve cardiovascular fitness, which is essential for overall health and can contribute to better workout performance and recovery.
Efficiency: Bodybuilders often have busy training schedules, with a need to target specific muscle groups with resistance training. HIIT provides an efficient way to incorporate cardiovascular training into their routines without spending extended periods on traditional steady-state cardio.
Muscle Preservation: When dieting for a competition, bodybuilders aim to retain as much muscle mass as possible while losing body fat. HIIT can help with muscle preservation because it places less stress on muscle tissue compared to prolonged, steady-state cardio.
Metabolic Benefits: HIIT’s ability to enhance metabolic rate and insulin sensitivity can be beneficial for bodybuilders seeking to optimize their nutrition and nutrient partitioning.
While bodybuilders may include HIIT in their training plans for these reasons, their primary focus is on resistance training to build muscle and sculpt their physiques. In contrast, HIIT primarily emphasizes cardiovascular fitness and can be used for general fitness, fat loss, and endurance.
It’s important to note that the relationship between bodybuilding and HIIT is more about using HIIT as a tool to complement the broader training and nutrition strategies employed by bodybuilders, rather than being an integral part of traditional bodybuilding training methods. Bodybuilders tend to customize their training regimens based on their specific goals and needs, which can include incorporating elements of HIIT when appropriate.
In summary, HIIT is not attributed to a single origin but rather evolved from a combination of training principles, research findings, and practical applications over the years. Its effectiveness and efficiency have contributed to its widespread adoption in the fitness world, making it a popular training method for people seeking to improve their overall health and fitness.
