The first one is High Intensity Interval Training, and the second one is HIIT. HIIT is a type of workout that involves short bursts of intense exercise followed by periods of rest. It is a popular type of exercise for people who want to lose weight and get fit. HIIT can be performed using stationary exercise equipment, such as treadmills, or by running, biking, or swimming. HIIT can also be performed by doing exercises that involve both strength and cardio training.
