Not necessarily. I-Min Lee, a professor of medicine at Harvard Medical School and an expert on the role of physical activity in preventing disease. Increasingly, cardiac rehabilitation programs which help people recover from heart attacks and related conditions are using tailored versions of HIIT.
Outside of such settings, HIIT may be unsafe for people who have or are at risk for heart disease. One of the largest randomized controlled trials of HIIT, published last year in BMJ Open , suggests that healthy people in their 70s can do these workouts with little risk. But in terms of longevity, moderate-intensity exercise seems to be just as good.
The main advantage to HIIT is that you can boost your cardiovascular fitness faster by working harder instead of longer. Some small, short-term studies hint that HIIT workouts can produce equal or greater improvements in blood pressure and blood sugar compared with moderate-intensity exercise.
The BMJ Open study included 1, healthy, active Norwegians with an average age of About half the control group were assigned to do 30 minutes of exercise most days. The other half swapped in moderate-intensity continuous training twice weekly see "A tale of two workouts".
Researchers compared two workout strategies in healthy adults ages 70 to 77 during a five-year study in Norway see main text for more details and results.
The moderate-intensity continuous training workout involved exercising for 50 minutes. Note: To get a rough idea of your maximum heart rate, subtract your age from During the five-year follow-up, just three people in the study had adverse events injuries from slipping while exercising outdoors.
There were no survival differences among the three groups, although there were slightly fewer deaths in the HIIT group. One possible explanation for the similarity in outcomes: People in the control group exercised more than expected including doing some high-intensity exercise , and only about half of those in HIIT group actually did regular high-intensity workouts.
Also, the people who agreed to participate in the study were more active than the general population, and they had a death rate that was about half of that expected in the general population of the same age. But the most important thing is to find an activity you enjoy and to keep doing it," says Dr.

Safety People who are deconditioned, recovering from injury, elderly, have overweight, or have medical conditions should be followed and monitored closely by their physician and an exercise professional, because of the higher intensity achieved with HIIT.
Example of a beginner HIIT workout This workout can be performed at home using just an exercise mat and a timer or clock. A 5-minute warm-up of walking or marching in place should be performed before the workout, and a minute cool-down of slower movements allowing the heart rate to gradually decrease, along with stretches, should be included to end the workout.
Cardiovascular disease Most research on HIIT and chronic disease is available for cardiovascular disease CVD. Hypertension Regular physical exercise, particularly vigorous aerobic exercise, has been studied to control hypertension, or high blood pressure. Pulmonary disease HIIT has been found as equally effective as MICT in improving aerobic endurance and reducing shortness of breath in people with chronic obstructive pulmonary disease COPD.
Obesity The Centers for Disease Control and Prevention and the American College of Sports Medicine recommend minutes weekly of moderate-intensity aerobic exercise for modest weight loss, and even longer durations for additional weight loss. Type 2 diabetes HIIT should only be performed in people with diabetes who have well-controlled blood glucose levels, and should be avoided if one has diabetic retinopathy, which increases the risk of detachment of the retina.

But as Mulgrew points out, the trainijg of HIIT lies in exertion, not the modality, so pretty much any form of exercise fits—and that includes the simplest form of cardio there is: walking.

At the conclusion of the study, the individuals had noticeably improved endurance and strength. Studies have shown that regular HIIT exercise can boost your memory and make you sharper in everyday decision-making.
In fact, it's just as effective to do a shorter interval session than a long moderate workout. A study compared two groups of college men for two weeks: those who did stationary bicycling at a moderate pace for roughly an hour-and-a-half to two hours for three times a week, and those who did six second all-out sprints with four minutes of recovery.
Surprise, surprise: The HIIT-ers were just as fit in terms of exercise performance and muscle growth as those moderate-intensity exercisers by the end of the trial—with far less time invested.
While resistance training is the gold standard for building muscleHIIT workouts can spur muscle growth as well. Whatever areas of the body your HIIT exercises focus on is where you're likely to see the muscle definition most often the core and legs. There are multiple studies to support this boost in overall health.
One caveat: The benefit is limited to those above the "normal" BMI range. You can actually tap into those HIIT benefits with a wide range of workouts. HIIT can be just about anything—from swimming to running to mountain climbers in your apartment to even weight training.

Heart disease accounts for one-quarter of deaths in the US, and improving cardiovascular health can reduce your risk for heart disease, making HIIT workouts a great investment. A small study of men ages 56 to 67 who performed a HIIT workout five days a week for six weeks found that the group had an average reduction of about 5. In addition, a study found that a session of HIIT resulted in a more immediate reduction in blood pressure than a session of steady-state cardio. HIIT training can also help control blood sugar levels, particularly for people with diabetes. A study found that after 8 weeks of HIIT, people with type 2 diabetes had improved control of their insulin levels and better pancreatic function. In addition, a scientific review looked at studies where participants did HIIT regimens for less than two weeks. It found that HIIT helped people with and without diabetes better control their blood sugars than continuous-state workouts. HIIT helps people to burn fat and carbohydrates within a short period of activity. People who do HIIT may also benefit from a revved up metabolism post-workout. HIIT has been shown to increase resting energy expenditure, which means your body is continuing to burn calories at an elevated rate even after you exercise. Consistent HIIT workouts over a period of weeks could help improve your sleep quality and increase the time you spend sleeping. A review showed that HIIT sessions of any type performed for more than 16 minutes per session for at least eight weeks can "significantly improve sleep quality" in adults. Additionally, doing HIIT workouts at least three times a week was associated with less time spent awake while in bed. In general, exercise is associated with better sleep. Sleep quality has many effects on general health, playing an important role in functions like memory, mood, and weight loss.

Incorporating HIIT into your exercise routine could bring additional benefits:. Regular exercise not only bolsters general health, but it may also boost brain health. Scientists found that people who exercise have larger brain regions that are responsible for thinking and memory. Recent science shows that incorporating high-intensity intervals into workouts may be even more beneficial for brain health. A small study looked at older sedentary adults who either did HIIT, MCT, or stretching to see how it affected their cognition. HIIT had the greatest effect on participants' memory performance. Research published in found that interval exercise increased blood flow in the brain. Less cerebral blood flow is associated with cognitive decline and dementia.

Because they're so short, you'll be working hard the whole time. The trade-off is that this format offers seasoned exercisers a new challenge and new exercisers a quick way to feel stronger — one of many benefits of HIIT workouts that other exercises just don't offer. HIIT may have you sucking wind, but you definitely won't be bored. Most people aren't used to pushing into the anaerobic threshold when your body needs to recruit energy stores already available without the assistance of oxygen. But HIIT asks you to enter this anaerobic zone often since there is a very limited time for rest. The short bursts or sprints of work require your muscles to burn glucose energy anaerobically as there isn't enough time for oxygen to help produce additional ATP adenosine triphosphate , which is your body's main energy source. The U. Department of Health and Human Services recommends adults get at least minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity activity weekly. High-intensity interval training is considered vigorous intensity and helps your heart and body improve their anaerobic threshold or the highest exercise intensity that you can sustain for a prolonged period without running out of ATP. One study found that after eight weeks of doing HIIT workouts, people could ride their bikes twice as long while at the same pace as they could before they started doing HIIT workouts.
