The whole workout can be done in just 4 minutes for Tabata more on this to come and up to 30 minutes for longer rounds. The key to a productive HIIT workout is to do it as quickly as possible with little rest in between all while making sure to have good form. Types of HIIT. Since HIIT workouts are generally characterized by intense bouts of fitness, followed by quick rest periods, a variety of workouts can apply. The type of HIIT can include anything including biking, jumping, sprinting.
Say you chose biking, in order to make it HIIT appropriate, you could sprint as fast as possible for about 30 seconds, then do a slow pace for a minute. This would count as one round which would then be completed 4 to 6 times in order to make one workout. In comparison, HIIT workouts can include a variety of exercise movements. This goes for eight rounds or a total of four minutes. Tabata is similar to metabolic resistance training. It differs from HIIT in terms of intensity and duration.
Most cardio is slow and steady whereas HIIT is quick and intense. Cardio exercise includes running, quick walking, biking, aerobic classes, dancing, or swimming. Cardio and aerobic exercise are the same, they just refer to slightly different mechanisms. Learn more here: Cardio vs. Aerobic vs. Anaerobic: Are they the same? HIIT Benefits. Since the intervals of HIIT are performed at max intensity, studies have shown that they can provide health benefits close to twice as much as moderate level exercise.
For this study, they tested a HIIT ratio of 20 seconds of full effort, followed by 40 seconds of rest. Yes, There Are 4 Rules. In one study , women participants completed six exercise sessions including aerobic exercise, HIIT, and resistance training. The participants were given carbohydrates and protein in order to measure how effectively their bodies burned the energy. After exercise, resting energy expenditure REE and resting energy rates RER were analyzed right after the exercise, 30 minutes after exercise, and 60 minutes after exercise.
On average, HIIT produced the greatest calorie burn post-exercise. Research shows that adults who are pre-hypertensive at greater risk of developing high blood pressure have improved resting blood pressure levels and C-reactive protein and inflammation, both of which have been linked to heart disease. The study found that patients who did eight weeks of HIIT on a stationary bike had blood pressure decrease as much as traditional endurance training. Since the main barrier of exercise is time, HIIT can be a promising alternative.
A review also found that HIIT both reduces blood sugar and also improves insulin resistance more than continuous standard exercise. Regulated blood sugar will give you better energy levels, less cravings, and help prevent diseases such as diabetes. The results come from going as hard as you can for a short period of time, resting, and then repeating.
There are a ton of benefits to high intensity interval training, or HIIT as it is commonly referred to. But they warn you can have too much of a good thing.
But your body is only able to handle a certain amount of stress at once. In a high intensity interval workout, your body release stress hormones like cortisol. Cortisol can enhance strength, improve immunity and reduce inflammation. With that said, too much has a negative effect on your body, and therefore, too much HIIT can also have negative effects. The key is recovery. There is a lot of research into this type of exercise and its effects on the body.
That translates on average to two 30 to minute HIIT workouts a week. So, two a week would be just fine. Start first with a mix of cardio and weight training times per week. Once your body is conditioned and your physical fitness is strong, begin by adding one HIIT workout to your routine a week in place of your usual cardio workout. Meaning for some, doing HIIT three to five times a week feels like a walk in the park while others may need a little less like two to three times a week," Nicholas explains.
Taking time off think: 48 to 72 hours gives fatigued muscles adequate time to recover. That said, if you're mixing up muscle groups, say, arms on Monday and legs on Tuesday, doing HIIT training on back-to-back days could be fine. Just listen to your body and take a recovery day if you're not feeling up to it. There's no doubt that HIIT is a calorie crusher. Known as excess post-exercise oxygen consumption EPOC , your body goes through an afterburn effect when you do a HIIT workout because it creates an oxygen deficit.
After an intense workout, your body needs additional oxygen to return to its normal metabolic state, and in this process, burns more calories 24 to 48 hours after your workout is over. While you're in the afterburn zone, you're also torching tons of fat.
The goal of the high-intensity portion of your workout is to go from the aerobic to the anaerobic zone, which helps burn fat, explains Rachel Henderson, MD , a non-surgical sports medicine and orthopedic physician at the Andrews Sports Medicine and Orthopedic Center in Birmingham, Alabama. Still, you want to avoid doing HIIT every day to avoid overtraining and injury. According to the ACE , doing too much high-intensity exercise, or any form of exercise, too often without proper recovery can also lead to metabolic issues, including overtraining syndrome and lactic acid buildup — all of which can put major distance between you and your goals.
There is plenty of research that shows that working out can help support your immune system, but doing too much of it, especially HIIT every day, can backfire. If you continue to train with low immunity, you open the opportunity for more infection. Because HIIT forces you to work to max exertion with minimal rest, you need to take some recovery days in between your sessions to allow your muscles to re-charge.
Doing HIIT two to three times a week is enough to reap its benefits without going overboard. Henderson says. Because HIIT is often full of plyometric movements , it can put some added pressure on your joints.
According to Dr. Henderson, the most common injuries associated with HIIT workouts "occur in the lower extremities, such as knee or ankle sprains and muscle or tendon strains, which can also occur with other high-impact activities, like running and jumping. To help keep injuries at bay, "it's important to maintain good form or neuromuscular control, particularly if fatigued," Dr.
Cornick says that proper recovery and stretching are essential, too. Because HIIT puts your body under an intense amount of physical demand, injuries are more likely. A simple solution is to not do HIIT every single day. Instead, weave in other types of workouts, like running , yoga and strength training. Be sure to change up the intensity, too, by varying the load, speed and tempo. LISS , anyone?
