My Health & Fitness column in the Aiken Standard this week is about the benefits and potential drawbacks of high-intensity interval training (HIIT). With this type of training, even a few minutes of very intense exercise can lead to improvements in fitness that are greater than can be achieved through longer training sessions at a lower intensity. But the level of effort needed to see these improvements may be too much for many people.
You can learn more about the benefits of high-intensity training from this recent article: Physiological adaptations to low-volume, high-intensity interval training in health and disease.
That article might be a dense for non-scientists, so a more user-friendly alternative is here: How 1 minute intervals can improve our health.
