HIIT produces rapid results
Since most of us are incredibly busy and overwhelmed, the urge for rapid results in the smallest amount of time is quite attractive.
Within the last few years, a new exercise trend called High-Intensity Interval Training (HIIT) has gained much more attention and fame, and for a good reason. HIIT involves short but intense bursts of exercise followed by different sets of reduced-intensity sessions in small proportions.
These workouts are incredibly powerful in torching calories due to something known as Exercise Post-Exercise Oxygen Consumption. High-intensity workouts need an extreme amount of energy and oxygen throughout the exercise. The body needs more oxygen after the exercise is over to help return to its normal condition.
This means that the body is a calorie-burning machine for up to 48 hours after the exercise session is finished.
Fundamentally you’re forcing your body to perform at burning calories when you aren’t actively exercising!
There’s a direct connection to the number of calories used during your workout, along with the total amount used after.
But bear in mind, to accomplish the best “after-burn effect,” you need to go hard throughout your workouts.
Is performing more crunches or planks enough?
Most people I’ve worked with believe the perfect way to burn fat is by simply performing more ab exercises.
You can crunch or plank as much as you can until you exhaust yourself, but this doesn’t burn the belly fat!
While training as hard as you can, it is crucial to understand for total stability and harm avoidance, you can do all of the abs exercises in the world, but if you don’t drop your body fat, you’ll never obtain these six-pack abs.
Slimming body fat comes down to decreasing calories consumed and raising calories burned.
Since HIIT training turns your body into a fat-burning system, it’s a superb training solution to burn total body fat, such as belly fat.
One study showed that individuals performing HIIT three times each week for 20 minutes dropped a mean of 4.4 lbs in 12 months with no dietary adjustments.
What’s even more notable is that HIIT workouts revealed a 17 percent reduction in abdominal fat!
However, let’s not overlook that nutrition will account for 80 percent of results.
The best way HIIT workouts work for weight reduction based on science
As soon as you work out in high intensity, the human body can not sustain long intervals. The body depletes its oxygen stores, and the muscles develop lactic acid. Once exercised, our body then tries to create these oxygen shops up and clear the lactic acid. This practice is called EPOC, or excess post-exercise oxygen intake. A supporting study proves that the EPOC process can boost our metabolism for many hours following a workout.
Why is it more powerful than going for a longer time?
You probably still wonder how this is any different from going for an activity for an extended period? After a run, your heart rate is raised, and you are tired. It goes back into the EPOC process. If you opt for the long term, you are not performing at a sufficiently high strength level. HIIT workouts are intended to be all-out for specific periods to trigger this reaction.
How long HIIT workouts need to be?
Studies have revealed multiple health benefits of doing HIIT for no more than three 10 minute sessions each week. But we propose combo-ing HIIT with conventional strength training.
How Often Do I have to perform HIIT?
When you discover how good are the benefits of HIIT, you will probably be tempted to perform the HIIT workouts daily.
But as these workouts can be quite demanding in the human body, I suggest doing them 3-4 days per week.
These workouts can also be performed alone or following a strength training exercise session.
So, if you are short of time, you can do a quick HIIT session that combines cardio and weights.
It is essential not to neglect that your body needs rest to recuperate. Not allowing enough rest may delay your results.
High-intensity interval training is highly effective
Another study group made almost the same conclusions after evaluating the study. Both Steady-State Cardio and High-intensity interval training are effective. The state both obtain “small gains and of comparable size, in human body fat levels and waist in overweight and obese adults.” However, they notice that HIIT is a much better option for steady-state cardiovascular, providing similar fat-loss benefits with less time spent at the gym.
Additionally, it is worth pointing out this exercise will have some possible drawbacks, as fat reduction is concerned. For many, a workout that burns plenty of calories will stimulate your appetite, which means you find yourself replacing the calories you have worked so toughly to burn off. There is also a phenomenon called moral licensing, by which being “great” permits you to be “bad.” To put it differently, you might wind up eating more meals following a high-intensity interval training since you feel as if you “earned” it.
What is more, a few studies demonstrate that in the event you burn a lot of calories through exercise, you usually spend less energy elsewhere. To put it otherwise, your system tries to “cap” the amount of energy you use daily. Past a certain point, increasing the amount of calories you burn off in the gym will not automatically burn more fat.
To sum up, there are several distinct ways to perform cardio. All of these have their spot at different times and for numerous men and women. While HIIT is still a very long way from being a magic bullet so far as fat reduction is concerned, no exercise will do much to reduce weight at the lack of a great diet.
How to Figure your fat-burning heart-rate zone
To discover what type of zone you ought to be performing in for moderate-intensity exercise, then follow these steps:
1. Determine your resting heart rate (RHR).
You can do so by sitting calmly in a chair for 3-5 minutes. This will determine your RHR.
2. Find your maximum heart rate.
The easiest way to calculate that is by subtracting your age from 220.
3. Measure your heart rate reserve (HRR).
Subtract your maximum heart rate in the resting heart rate (in step 1).
4. Determine the max and low limits of your average intensity exercise zone.
Fill these numbers into these formulas:
(HRR X .50) + RHH = Start of your average intensity exercise zone
(HRR X .70) + RHH = Limit of your average intensity exercise zone
For example, a 30-year older’s maximum heart rate is 190 bpm, and he discovered his RHR to become 70 bpm. This implies that his HRR is 120 bpm. While exercising, the period that his heartbeat is between 130 and 154 bpm is deemed moderate intensity, and the time their heartbeat is over 154 bpm is considered vigorous intensity.
Maximizing Fat Burn with HIIT
High-Intensity Interval Training (HIIT) is a powerful tool for torching body fat swiftly and efficiently. Incorporating HIIT into your fitness routine can accelerate fat loss by elevating your metabolic rate, even hours post-workout. The dynamic bursts of high-intensity exercises, interspersed with short recovery periods, optimize calorie burn and enhance cardiovascular fitness.
Tailoring HIIT for Optimal Results
Customize your HIIT workouts to target body fat by incorporating a variety of exercises that focus on multiple muscle groups. Exercises such as burpees, high knees, and mountain climbers are not only potent for fat burning but also enhance overall body strength and endurance. Ensure that the workouts are challenging yet suitable for your fitness level to prevent injuries and promote consistent progress.
Strategic Planning for HIIT Sessions
Plan your HIIT sessions strategically to maximize fat-burning potential. Incorporate a mix of cardiovascular exercises and strength training to promote muscle retention while focusing on fat loss. Ensure that the workouts are varied and progressively challenging to prevent plateaus and maintain a consistent fat-burning momentum.
Latest Science-Based Data
Recent studies underscore the effectiveness of HIIT in promoting fat loss and improving metabolic health. A well-structured HIIT workout can elevate the metabolic rate, promoting calorie burn even post-exercise. It is also associated with improved insulin sensitivity and cardiovascular health, making it a comprehensive workout strategy for overall fitness.
