What is intensity workout

Develop and improve products. List of Partners vendors. High-intensity workouts are the latest trend in fitness. But what does that actually mean? Working to the point of complete muscle fatigue or until you throw up? Or something a little less intense, but hard enough that you can't talk. One of the most important elements is the intensity of your workout, so it is important to get it right.

While most guidelines recommend moderate-intensity exercise most days of the week, working at a high intensity can help you burn more calories, save time with shorter workouts , and increase your fitness level.

So, how do you know if you're working at a high or vigorous intensity level? There's no precise definition, but there are ways to monitor how hard you're working:. It's good to work at a variety of intensity levels to tap into different energy systems and work your body in different ways.

Too much high-intensity exercise could lead to burnout or overuse injuries, so you don't want to do this kind of exercise every day. If you're a beginner, starting with interval training is a great way to get your body used to higher intensity exercise, in short, manageable bites. When your body is going all-out during true HIIT, it relies on your anaerobic pathways breaking down glucose without oxygen to produce the energy it needs to fuel you.

This provides an immediate supply of energy, but the amount is very limited—which means the length of time you can sustain that max effort is quite short, says Tamir. Recovering before the next interval is essential: Forcing your body to repeatedly acclimate between two very different states provides excellent cardio conditioning, Franci Cohen, M.

There are other benefits too, including increases in VO2 max how much oxygen you can use during exercise and improvements in insulin sensitivity how responsive your cells are to insulin , blood pressure, and cardiovascular function, according to a review published in the journal Sports Medicine.

This also makes it a convenient form of exercise for those who are short on time. But you can use HIIT in strength-based workouts too.

So that means the afterburn effect is greater after the intervals — but it peters out after a while. I saw the same effect when I entered a metabolic chamber to measure my metabolism. In the periods after I hit the exercise bike, my metabolic rate ramped up — but only by a few more calories each minute, and the effect wore off within half an hour of exercising. Building more muscles, however, can be a little more helpful for the afterburn.

At any given weight, the more muscle on your body, and the less fat, the higher your metabolic rate. But that takes work — a lot more work than a short aerobic HIIT workout. And even a short HIIT workout may not be for everyone. Our mission has never been more vital than it is in this moment: to empower through understanding.

How to get the most out of your exercise time, according to science.

Reddit Pocket Flipboard Email. The most well-established benefit of interval training has to do with heart health.

Here's an example: You stop exercising and take your pulse for 15 seconds, getting 37 beats. Multiply 37 by 4, to get If you're 45 years old, this puts you in the target heart rate zone for vigorous exercise, since the target zone for that age is between If you're under or over your target heart rate zone, adjust your exercise intensity.

It's important to note that maximum heart rate is only a guide. You may have a higher or lower maximum heart rate, sometimes by as much as 15 to 20 beats per minute. If you want a more specific range, consider discussing your target heart rate zone with an exercise physiologist or a personal trainer.

Generally only elite athletes are concerned about this level of precision. They may also use slightly different calculations that take into account sex differences in target heart rate zones. These differences are so small that most casual athletes don't need separate calculations for men and women. Also note that several types of medications, including some medications to lower blood pressure, can lower your maximum heart rate, and then lower your target heart rate zone.

Ask your doctor if you need to use a lower target heart rate zone because of any of your medications or medical conditions. Interestingly, research shows that interval training, which includes short bouts around 15 to 60 seconds of higher intensity exercise alternated with longer, less strenuous exercise throughout your workout, is well tolerated. It's even safe for those with heart disease and type 2 diabetes.

This type of training is also very effective at increasing your cardiovascular fitness and promoting weight loss.

You'll get the most from your workouts if you're exercising at the proper exercise intensity for your health and fitness goals. If you're not feeling any exertion or your heart rate is too low, pick up the pace. If you're worried that you're pushing yourself too hard or your heart rate is too high, back off a bit.

Before starting a vigorous exercise program, you may want to talk with your doctor. He or she may suggest that you have certain tests first.

This may be the case for people who have diabetes or more than one risk factor for heart disease, and for men over age 45 and women over age There is a problem with information submitted for this request.
