Any type of exercise is good for your health. But in a recent study, researchers found that a specific type called high-intensity interval training (HIIT) may improve age-related changes in a person’s cells.
In the study, published in the journal Cell Metabolism, researchers measured the body mass index and insulin sensitivity of two groups of older and younger people (between ages 18 to 30, and those from 65 to 80). The people were then split into three groups to try different types of exercise.
