High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. [1] HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts.
Research has shown that interval training like HIIT may be better for fat loss than continuous endurance training since it seems to promote fat-burning by using fat as fuel during exercise. HIIT ...

Aerobic exercise, also known as cardio, is physical exercise [1] of low to high intensity that depends primarily on the aerobic energy-generating process. [2] " Aerobic" is defined as "relating to, involving, or requiring oxygen", [ 3 ] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [ 4 ]
Cardiovascular fitness is a component of physical fitness, which refers to a person's ability to deliver oxygen to the working muscles, including the heart.Cardiovascular fitness is improved by sustained physical activity (see also Endurance Training) and is affected by many physiological parameters, including cardiac output (determined by heart rate multiplied by stroke volume), vascular ...
One 2015 study (of healthy men) that compared calorie burn after 30 minutes of HIIT to other forms of steady-state exercise noted that HIIT burned 25 to 30 percent more calories.
"Most HIIT sessions have a 2:1 ratio in terms of time. For example, for running, a HIIT session may be something as 60 seconds jog, 30 seconds sprint." First of all, that second sentence contains questionable English. More importantly, I think it's backwards. As I understand it, it is 2:1::high-intensity:low-intensity.
