High intensity interval training, or HIIT, is a type of training that involves short bursts of high-intensity intervals of exercise combined with lower-intensity intervals. One example is all-out sprinting for 30 seconds between 60-second jogging sessions. One workout would involve five to 10 of those high-intensity cycles. This type of workout is designed to burn large amounts of fat in a short period of time.
Belly fat is, in fact, the colloquial term for abdominal fat. According to medical experts, belly fat can be potentially dangerous. Excess of it can lead to a number of health problems including heart diseases, high blood pressure, type 2 diabetes, a decrease in the level of HDL or good cholesterol, and can even lead to strokes or sleep apnea. You need to combat this problem before it gets too late.

A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.


Eric recommends lifting weights three times a week, especially if you're starting out. It's also best to focus on compound exercises, which are exercises that target groups of large muscles, such as barbell squats, deadlifts, and leg presses. "Compound movements concentrating on larger muscle groups will burn the most calories," Rachel Gerson, an NASM-certified personal trainer, told POPSUGAR. "If you think about it, you'll feel a lot more tired after doing a barbell squat than doing a bicep curl."

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.
