There's recently been a strong increase in people who choose to practice HIIT, High-Intensity Interval Training, in hopes of keeping their body healthy and fit. However, there are many aspects in which this workout type isn't the best for your body.
Low impact cardio includes certain exercises focused on moving the body while raising your heart rate gradually to an optimal zone. While it's increased with every movement, with different ways to maintain blood flow and blood pressure, the heart rate is lowered with small breaks in between, even though they aren't enough to allow a significant drop. On the other hand, HIIT demands a higher and more sudden heart rate raise, which increases exhaustion levels.
People who choose HIIT often end up collapsed on the floor after a session, completely exerted. Although this is seen as the best way to achieve the results you were looking for, it often requires a good amount of motivation to begin exercising. Instead, low impact cardio workouts are easier to include in your everyday routine, as they don't stress your body excessively nor leave you gasping for breath after working out. Even though it may not seem as important, not having to psych yourself up for exercise can help your mind and body make the most of it.
Other reasons why low impact cardio can bring you more health benefits to your body are related to your body's cortisol production. This is also called the stress hormone and is triggered not only by everyday worries but also by certain types of exercise. As you may have guessed, HIIT boosts a higher cortisol response than low cardio workouts.
We are not saying HIIT training sessions are bad, however, you should always check your doctor before starting any high-intensity training.
Benefits of HIIT training you may not be aware of
It helps you burn fat
The intensity of the exercises HIIT provides lead to an increased rate of fat oxidation as well as excess post-exercise oxygen consumption, which occurs when the body recovers from its oxygen-deprived state during the HIIT exercise. During this stage, adipose tissue are broken down and converted into fuel.
It regulates your appetite
If you overindulge more than once, HIIT will help you manage your appetite as it causes a decrease in the amount of ghrelin (an appetite-regulating hormone) which reduces your appetite. At the same time, HIIT also increases your blood sugar and blood lactate level temporarily, which also brings your appetite down.
It increases the amount of oxygen your body can absorb in a minute
HIIT affects the physical capacity of your athletic performance and your body has better endurance in aerobic exercises. Besides improving athletic conditioning it also brings us better overall health.
It regulates blood glucose levels
People suffering from pre-diabetes or type II diabetes can benefit significantly from HIIT because the sport actually increases glucose metabolism and insulin sensitivity, thus helping to regulate blood glucose at healthy levels.
It is a more efficient form of cardio exercise
HIIT makes it easier to hit the desired number of cardio hours that you need to clock because it’s far more time-efficient. In fact, every hour of HIIT is roughly equivalent to 4 hours of conventional endurance training!
