Interval Training
The so-called intermittent exercise refers to a "training mode" that achieves intense training by alternating between training and rest.
Here's an example.
Suppose I first do 30 to 60 seconds of intensive anaerobic exercise, followed by a short rest of 1 to 2 minutes. Through such repeated intermittent exercise, I can consume a large amount of oxygen and stimulate muscle activity in a short period of time, and then use a short rest period in the middle to allow my heart rate to recover.
Generally, the more common intermittent exercises include HIIT and TABATA, etc.
HIIT is the abbreviation of High Intensity Interval Training. It is a combination of high-intensity exercise performed within 15-20 minutes. The training intensity is set at more than 80% of the maximum heart rate. The purpose is to make the body and muscles feel tired, and the body begins to consume a large amount of oxygen. Simply put, HIIT can not only increase cardiopulmonary capacity and muscle mass, but also improve metabolic power and insulin sensitivity.
