The major reason HIIT works so well for dropping body fat is due to the greater calorie burn (or EPOC—excess post-exercise oxygen consumption) that's maintained after the workout is over. In other words, you burn more calories and more body fat while you're sitting around doing nothing. In addition to this increase in resting metabolism, HIIT is effective at enhancing the mechanisms in muscle cells that promote fat burning and blunt fat storage.
You may have an apple-shaped or a pear-shaped body structure. Accumulation of fat occurs differently for different people, it actually depends on the body structure. For those whose bodies are pear-shaped, the fat tends to accumulate in the lower part of the body, like the buttocks. But for those whose bodies are apple-shaped, your body tends to store fat around the middle section, thus resulting in fat accumulation around the belly. You must know that there are two types of belly fat – visceral, which accumulates around the abdominal organs, and subcutaneous, which occurs between the skin and abdominal wall.
On HIIT 100s sets during Weeks 1-3, when rest periods are 30 seconds or more, perform the first three sets of 10 as fast and explosively as possible. This will help build more muscle power and strength, despite using such light weight. On Sets 4-6, keep the movement slow and controlled, focusing on the contraction and squeezing each rep at the top for one to two seconds. This helps establish a strong mind-muscle connection, which is critical for muscle size, shape, and separation.
Earlier, belly fat was considered healthy; it was perceived as a reservoir of adipose tissues that could be utilized when a person needed extra energy. With time, the views have changed. Researchers state that excess belly fat triggers chronic cardiovascular diseases. So, it is important to measure belly fat and check how much you need to reduce. Here are some parameters to measure your waistline.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
