What is Micro HIIT and How You Can Benefit From It

Micro HIIT is essentially a HIIT (high intensity interval training) workout where you push yourself harder than you normally would over the course of less repetitions.

It’s all about exercising in even shorter, sharper bursts which push your body into the higher heart rate zones quicker than you would do in a normal HIIT workout.

The benefits of Micro HIIT workouts have recently been promoted in a study by The American College of Sports Medicine Journal which found that seven minutes of intense HIIT exercise is enough to get the fitness benefits.

These shorter, more intense workouts are appealing to many, as it’s much easier to work at max-effort for a shorter time and the benefits remain largely the same, helping to boost your metabolism not just while you are working through the intervals, but for a period of time post workout. In addition, a recent study published in the journal Cell Metabolism, found that bouts of Micro HIIT can slow down cellular aging.

Who can benefit? 

Micro HIIT or mini bursts of intensive exercise can be beneficial for a large number of people, especially for those who do not have a lot of time to spend exercising.

One of the beauties of Micro HIIT is that you can switch up your training methods by partaking in shorter burst of exercise which can be done throughout the day I.e. first thing in the morning, on your lunch break, or even when you’re waiting for the kettle to boil, or lunch/dinner to cook.

Micro HIIT is also incredibly beneficial for those looking to reduce body fat, or who are worried about the fat stored around their middle, which could indicate higher insulin levels. Insulin is the hormone that regulates the levels of glucose in the blood, which could result in weight gain when the cells absorb too much glucose, converting it into fat. According to research in the journal Frontiers, Micro HIIT training programmes can have positive effects on those at risk of type 2 diabetes.

The healthy stress your body undergoes during HIIT or Micro HIIT sessions triggers autophagy, which put simply is the process your body goes through to clean out damaged cells and regenerate newer, healthier cells to help the body achieve optimum health, as well as being anti-ageing. The autophagy process has also been linked to the reduction of neurodegenerative diseases and the treatment of cancer.

The Micro HIIT workout below is a small example taken from the newly launched Freeletics 15-minute Training Journey which offers six weeks of 15-minute bodyweight only workouts which can be done anytime, anywhere and with no equipment.
