Is Interval Training Right for You?

Updated: May 19

Interval training, also known as high-intensity interval training (HIIT), is a type of workout that involves alternating short bursts of intense exercise with periods of rest or lower-intensity activity. It has become increasingly popular in recent years due to its numerous benefits and time-efficient nature.

One of the main benefits of interval training is that it can help you burn more calories in a shorter amount of time. During high-intensity intervals, your body has to work harder to maintain the intensity, which can increase your heart rate and metabolism. As a result, you can burn more calories in a shorter time than steady-state cardio, such as jogging or cycling at a consistent pace. In fact, research has shown that interval training can lead to more significant fat loss compared to steady-state cardio, even when the total duration of the workout is the same. For example, a meta-analysis published in the Journal of Obesity in 2012 found that interval training was more effective at reducing body fat and improving insulin sensitivity compared to steady-state cardio.

Interval training can also improve your cardiovascular fitness and endurance. By challenging your body with short bursts of intense exercise, you can train your heart and lungs to work more efficiently, which can help you perform better during endurance activities like running or cycling. In addition, interval training can increase your VO2 max, which is a measure of how much oxygen your body can use during exercise. A higher VO2 max is associated with better cardiovascular fitness and endurance. A study published in the Journal of Applied Physiology in 2006 found that interval training was more effective at increasing VO2 max compared to steady-state cardio.

In addition to improving your physical fitness, interval training can also have numerous mental and emotional benefits. It can help reduce stress, improve mood, and boost confidence, as the sense of accomplishment that comes from pushing yourself to your limits can be incredibly rewarding. Exercise in general has been shown to have a positive effect on mental health, and the high-intensity nature of interval training may lead to even greater benefits. A study published in the Journal of Aging and Physical Activity in 2010 found that interval training can improve cognitive function in older adults.

Another advantage of interval training is that it can be done with any type of exercise, including running, cycling, swimming, and even bodyweight exercises like push-ups and squats. This makes it a highly versatile and convenient way to incorporate intense exercise into your routine. You can do interval training in a gym, at home, or outdoors, and you can adapt it to suit your fitness level and goals. A review published in the Journal of Sports Sciences in 2016 found that interval training can improve cardiovascular fitness, muscle endurance, and muscle strength.

Finally, interval training can be a great way to break up the monotony of traditional workouts and keep things interesting. By constantly changing the intensity and type of exercise, you can avoid boredom and keep your body guessing, which can lead to better results. You can also mix up your intervals by using different exercises and changing the duration and intensity of each interval. This can help keep you motivated and prevent burnout. A study published in the Journal of the American Medical Association in 2005 found that interval training was as effective at improving cardiovascular health as steady-state cardio, but required significantly less time to complete.

Overall, interval training is a highly effective and time-efficient way to improve your physical and mental fitness. Whether you're a seasoned athlete or just starting out, incorporating interval training into your routine can help you achieve your fitness goals and lead a healthier, more active lifestyle. So why not give it a try and see what benefits it can bring to your fitness journey?
