A new study published in the journal Cell Reports Medicine suggests that even a few minutes of intense exercise can trigger meaningful changes in the body. Researchers comparing three-minute and 90-minute workouts found that the shorter burst rapidly increased circulating molecules associated with metabolism and better health. While brief exercise is not necessarily a replacement for longer workouts, the findings show how quickly the body can respond to vigorous activity.
