Simple isometric exercises, including wall sits, offer a natural strategy to lower blood pressure

Out of multiple forms of physical activity, isometric exercise came out on top as “the most effective mode in reducing both systolic and diastolic blood pressure”

Broken down to individual exercises, wall squats (isometric) were the most effective for reducing systolic blood pressure while running (aerobic) was most effective for reducing diastolic blood pressure

About eight minutes of isometric training three times a week may be enough to significantly lower blood pressure

Wall squats, planks, glute bridge and the overhead hold are examples of simple isometric exercises you can do virtually anywhere

For the 48.1% of U.S. adults with high blood pressure,¹ learning how to do simple isometric exercises, including wall sits, may offer a natural strategy for relief. In fact, a systematic review and meta-analysis of 270 randomized controlled trials looked at the effects of multiple types of exercise, including aerobics, high-intensity interval training (HIIT), resistance training and combined training, on blood pressure.

While all were beneficial, isometric exercise came out on top as “the most effective mode in reducing both systolic and diastolic blood pressure.”² It turns out that static contraction of muscle as you hold your body in one position, i.e., isometric exercise, may offer blood pressure benefits that some other types of more dynamic movement don’t.

Isometric Exercises Improve Resting Blood Pressure

When it comes to exercise recommendations to lower blood pressure, cardio aerobic-type exercises typically come to mind. But, according to researchers from Canterbury Christ Church University, this is outdated advice based on older study data that excludes HIIT and isometric exercise.³

The meta-analysis, which included clinical trials that analyzed the effects of exercise for two weeks or more on resting blood pressure, found all types of exercise led to significant reductions in resting systolic and diastolic blood pressure. However, the greatest reductions occurred after isometric training.⁴

The top number of your blood pressure measurement, the systolic, is a measurement of the maximum pressure inside your arteries as your heart contracts. The bottom number, the diastolic, is a measurement of the pressure in your blood vessels when your heart is not contracting. Both numbers are important in determining how much damage may occur over time to your blood vessels and other organ systems.

Effectiveness based on the “surface under the cumulative ranking curve” (SUCRA) values for systolic — which refers to the mean probability of being the best for lowering your systolic blood pressure — placed isometric exercise in the No. 1 slot with an effectiveness rating of 98.3%, followed by combined training (75.7%), dynamic resistance training (46.1%), aerobic exercise training (40.5%) and high-intensity interval training (39.4%).⁵

In rank order, the analysis found significant reductions in resting systolic blood pressure and diastolic blood pressure:

• Isometric exercise (–8.24/–4.00 mmHg)
• Combined training (–6.04/–2.54 mmHg)
• Dynamic resistance training (–4.55/–3.04 mmHg)
• Aerobic exercise (−4.49/–2.53 mmHg)
• High-intensity interval training (–4.08/–2.50 mmHg)

Broken down to individual exercises, wall squats (isometric) were the most effective for reducing systolic blood pressure while running (aerobic) was most effective for reducing diastolic blood pressure. Overall, however, isometric exercise worked best for lowering both systolic and diastolic blood pressure. Study author Jamie O’Driscoll told The Washington Post:⁶

“Our main message is that actually engaging in exercise is fantastic and any exercise might reduce your blood pressure. But if you’re an individual who is currently exercising to the guidelines and you’re still having a bit of difficulty reducing that blood pressure and you want to avoid going on medication, perhaps isometrics is an additional mode to complement the exercise you’re already doing.”

What Are Isometric Exercises?

Isometric exercises are low-impact movements that involve holding a position so the same muscle length is maintained, tiring out your muscles to fatigue.⁷ “Any kind of an exercise that is holding tension in any position which doesn’t involve dynamic movement is generally isometric exercise,” study author Jamie Edwards told The Washington Post.⁸ In other words, static contraction defines isometric exercise, examples of which include:⁹

In addition to blood pressure benefits, isometric strength exercises may help strengthen joints better than dynamic strength training,¹⁰ and it’s useful for reducing pain while increasing range of motion and functional ability in people with knee osteoarthritis.¹¹ Isometric training is also beneficial for relieving neck pain, improving joint mobility and improving neck dysfunction.¹²

Past research similarly revealed that isometric resistance training reduces systolic blood pressure by nearly 7 mmHg and diastolic blood pressure by close to 4 mmHg. Performing isometric handgrip exercise also significantly reduces systolic blood pressure and mean arterial pressure, offering another accessible tool for blood pressure health.

As the scientists explained in the journal Medicine, “Low- to moderate-intensity isometric handgrip exercise can be performed anywhere, requires relatively inexpensive equipment, and does not elicit the same level of cardiovascular stress as aerobic exercise.”¹³ As for how isometric exercise lowers blood pressure so effectively, The Washington Post reported:¹⁴

“Isometric exercises effectively lower blood pressure because contracting a muscle and holding the position temporarily reduces blood flow to that muscle, O’Driscoll said. When you release that contraction, blood flow through the muscle tissue increases. This produces important signals that prompt blood vessels to relax more and creates less resistance to blood flow, which ultimately reduces blood pressure, O’Driscoll said.”

Eight Minutes of Isometric Exercise, Three Times a Week

How much isometric exercise is necessary to lower blood pressure? Isometric exercise training programs often use protocols involving four, two-minute contractions separated by one to four-minute rest intervals. The sessions are done three times a week.¹⁵ In other words, about eight minutes of isometric training three times a week may significantly lower blood pressure.

A wall sit is one straightforward option that can be easily done in two-minute increments, followed by two minutes of rest and repeated four times. The entire workout is then repeated three times each week. “On average, a regular isometric routine of wall sits lowered systolic blood pressure (the top number) by 10 mmHg and diastolic pressure by 5 mmHg, according to the research,” The Washington Post reported.¹⁶

Meditation Exercises Also Lower Blood Pressure

On the topic of low-impact forms of exercise that are useful for maintaining healthy blood pressure, meditation exercises, particularly qigong, are useful for lowering diastolic blood pressure in people with elevated levels,¹⁷ while research shows meditation may also help lower blood pressure with just three months of practice, while at the same time decreasing psychological distress and increasing coping ability among young adults.¹⁸

Another group of researchers conducted a meta-analysis involving 13 studies on meditation and yoga for blood pressure health. Blood pressure decreased in response to both meditation and yoga, and meditation appeared to be particularly useful in decreasing the blood pressure of subjects older than 60 years.¹⁹

The calming effect of meditation has also been shown in numerous studies to benefit blood pressure. In a 2019 study published in the Journal of Human Hypertension, mindfulness meditation was evaluated for its effects on not only blood pressure but also anxiety, stress and depression.

For an eight-week period, participants engaged in mindfulness training for two hours a week, or participated in a control group involving health education talks. The meditation group had lower blood pressure monitoring values after the intervention, and were also less judgmental, more accepting and less depressed than the control group.²⁰

Practicing “mindfulness” means you’re actively paying attention to the moment you’re in right now. Rather than letting your mind wander, when you’re mindful, you’re living in the moment and letting distracting thoughts pass through your mind without getting caught up in their emotional implications.

What Else Works to Lower Blood Pressure?

If your blood pressure is running high, you need to restore your insulin and leptin sensitivity, and the following strategies are among the most effective for doing so:

• Replace processed foods with whole, unprocessed organic foods.
• Avoiding seed oils — It would be helpful to also eliminate seeds and nuts unless you have been on a low-LA (linoleic acid) diet for at least three years.
• Optimize your vitamin D level.
• Only use healthy fats — Sources of healthy fats to add to your diet include grass fed butter, raw organic dairy, organic pastured egg yolks, coconuts, coconut oil and macadamia nuts and grass fed meats. The best carbs to add would be ripe fruit that you tolerate well. But the key is to make sure your fat intake is below 30%, which you can determine with Cronometer. If you fail to do this, the carbs can convert to fat and change your cholesterol profile unfavorably.
• Exercise regularly.

Optimizing your sodium to potassium ratio is also important. It’s generally recommended that you consume five times more potassium than sodium, but most Americans get the opposite ratio, eating two times more sodium than potassium. If you eat a lot of processed foods, which contain processed table salt, your sodium to potassium ratio is likely out of balance.

While conventional health care practitioners may suggest you remedy this by limiting salt intake, especially when it comes to lowering the risk of high blood pressure, focusing on increasing potassium is key. Research shows an association between higher potassium intake and lower blood pressure, regardless of sodium intake.²¹

To improve your ratio, eliminate processed foods, which are very high in processed salt and low in potassium and other essential nutrients. When using added salt, use a natural salt such as Himalayan salt. Further, eat a diet of whole, unprocessed foods, ideally organically and locally-grown to ensure optimal nutrient content.

This type of diet will naturally provide much larger amounts of potassium in relation to sodium. In my view the absolute best way to increase your potassium is by eating ripe fruit. Taking potassium supplements is not a good strategy and will simply not provide you with the benefits you are seeking. Other examples of potassium-rich foods include:²²

Latest Obesity Drugs to Do Wonders for Blood Pressure — How Perfect

Eli Lilly’s obesity drug tirzepatide — brand name Zepbound — is being positioned as the latest breakthrough to lower blood pressure. The U.S. Food and Drug Administration approved tirzepatide to manage Type 2 diabetes in 2021, under the brand name Mounjaro, a direct competitor to semaglutide (Ozempic). It was then approved to treat obesity in 2023,²³ competing with the popular weight loss drug Wegovy.²⁴

Now, however, tirzepatide is being said to “do wonders” for blood pressure,²⁵ after research published in the journal Hypertension²⁶ found it led to an average 7.4 mmHg drop in systolic blood pressure among those taking the lowest dose. Those taking the highest dose had an average drop of 8 mmHg.²⁷ In a statement from the American Heart Association, study author Dr. James A. de Lemos said:²⁸

“Although tirzepatide has been studied as a weight loss medication, the blood pressure reduction in our patients in this study was impressive. While it is not known if the impact on blood pressure was due to the medication or the participants’ weight loss, the lower blood pressure measures seen with tirzepatide rivaled what is seen for many hypertension medications.”

The news came just days before an announcement by former director of the U.S. Centers for Disease Control and Prevention Tom Frieden called for high blood pressure to be the “focus of the next breakthrough”:²⁹

“In 2023, the weight-loss drug Wegovy and similar medications were a scientific and cultural — and profit-making — breakthrough … But what if we had medications that cost 5,000 times less and are better at preventing heart attacks and strokes? And what if only 1 in 5 people who need these medications get them? That’s the situation with drugs to treat high blood pressure — and it needs to change.”

It seems to be the perfect setup to roll out the next “blockbuster” blood pressure medication, but tirzepatide can cause side effects ranging from nausea and diarrhea to hair loss and gastroesophageal reflux disease.³⁰

It also causes thyroid C-cell tumors in rats and, according to the FDA, “contains warnings for inflammation of the pancreas (pancreatitis), gallbladder problems, hypoglycemia (blood sugar that is too low), acute kidney injury, diabetic retinopathy (damage to the eye’s retina) in patients with Type 2 diabetes mellitus and suicidal behavior or thinking.”³¹

Given these significant risks, it’s important to remember that blood pressure can often be effectively lowered via lifestyle changes, including simple isometric exercises.
