No Time for Exercise? Try High-Intensity Interval Training (HIT)

With high-intensity interval training, you reap the benefits of exercise without spending hours at the gym.HIT

We all know that exercise is good for us, and we’ve heard that we should be getting 30 to 60 minutes per day most days of the week. But in today’s fast-paced world, where the demands of work, child care, and home maintenance seem to endlessly steal from our ever-shrinking depot of availability, finding the time to meet these recommendations can be quite a challenge.HIT

What if there was a form of exercise that would allow you to reap the many health benefits of regular physical activity in just a quarter of the time? According to a recent review written by Australian researchers, high-intensity interval training (HIT) is a form of exercise that may do exactly that. Mounting evidence cited by the authors suggests that HIT is a time-efficient and effective alternative to traditional endurance exercise for boosting weight loss, aerobic stamina, and cardiovascular and metabolic health (1).HIT

What is HIT?

HIT involves alternating intense bouts of exercise, ranging from 30 seconds to several minutes, with recovery periods spanning one to five minutes. For example, a cyclist might incorporate HIT by pedaling as fast as possible for 30 seconds against a strong resistance, lowering the resistance and leisurely cycling for 4 minutes, and then repeating this alternating schedule 4 to 6 times per session.HIT

Such a training regimen adds up to about 20 to 25 minutes of exercise, which has shown substantial benefits when performed as few as three times per week. Just 2.5 hours of HIT completed over a total of 2 weeks has demonstrated benefits that are equivalent to 10.5 hours of continuous moderate exercise.

Improved Body Composition HIT

HIT has been shown to reduce body fat, particularly abdominal fat. In comparison with continuous moderate exercise, HIT increases energy expenditure and fat burning to a greater extent in the minutes and hours after a workout . This “after burn” is formally known as excess post-exercise oxygen consumption (EPOC) and reflects the body’s extra use of energy to replenish depleted fuel stores, repair cells, and restore hormonal and other body systems to their pre-exercise state. This is the prime time to Consume an Isagenix Shake. HIT

In addition to increasing EPOC to a greater extent than traditional endurance exercise, HIT also promotes greater releases of growth hormone. This transient increase in growth hormone may be important during the post-workout period when muscles are primed for growth. During exercise, muscle damage occurs and muscle synthesis stops. Spikes of growth hormone promoted by HIT may quickly mitigate protein breakdown after exercise and serve as a signal for muscle growth.HIT

HIT may also help preserve muscle mass in other ways. During long bouts of steady-state exercise, glycogen (the storage form of sugar) becomes depleted, and the body begins to break into its muscle reserves to get protein that can be used for energy. Because HIT relies on intervals of intense exercise broken up by intervals of more leisure, less intense exercise, muscle reserves are better preserved. Together, increases in growth hormone and the protection of muscle protein results in the preservation of muscle mass, which keeps metabolism running high and supports greater fat loss over the long term.HIT

HIT is for (Almost) Everyone

Most people can benefit from HIT. Studies have shown that it is safe and effective for those with health conditions such as diabetes and cardiovascular disease, and offers numerous advantages for healthy people simply looking to save time or switch up their workouts (1). Even professional endurance athletes are using HIT to improve performance by incorporating it alongside traditional endurance exercise in a comprehensive training program.HIT

HIT is a fun way to break up the monotony of conventional workouts, and according to the Australian researchers, may even be easier to stick to than traditional endurance training. HIT can yield substantial health and fitness benefits with minimal time commitments, making it the perfect prescription for those who don’t have 30 to 60 minutes every day to meet the current exercise recommendations. However, before starting HIT or any other exercise program, a consultation with a person’s physician is advised to determine if appropriate. HIT
