A Simple Way to Reduce Blood Pressure

A Simple Way to Reduce Blood Pressure

If you’ve been told you have high blood pressure, you’ve probably been told to do the classics like, walk more, eat better, reduce stress, maybe lose a bit of weight.

Sure this is all solid advice, but Isometric training, exercises like wall sits and planks, is one of the most effective ways of lowering resting blood pressure. It's actually three times more effective than walking.

What are isometric exercises?

Isometric simply means your muscles are working, but you’re not moving. Think exercises like wall sits, planks, holding the bottom of a lunge, or squeezing a handgrip.

No repetitions. Just controlled tension and breathing. They’re simple, low impact, and you can do them pretty much anywhere.

What does the science say?

A large meta-analysis published in the British Journal of Sports Medicine in 2023 compared aerobic training, resistance training, HIIT and isometric exercise. The result showed that Isometric exercise produced the largest average reductions in resting blood pressure [1].

The average reductions were around 8–9 mmHg systolic and 4–5 mmHg diastolic. That’s clinically meaningful. Even a 5 mmHg drop in systolic blood pressure is associated with a substantially lower long-term risk of stroke and heart disease.

Earlier systematic reviews and meta-analyses have shown similar results, particularly with isometric handgrip and wall squat training [2, 3].

Why does it help?

When you hold a strong contraction, blood flow to the working muscle is temporarily reduced. When you relax, blood rushes back through. Over time, repeatedly compressing and releasing the tension improves how well your blood vessels dilate.

Better vessel function means lower resistance in the system, and lower resting blood pressure. Although your blood pressure rises during the hold itself, that’s normal.

What does a typical routine look like?

Many studies use something very simple: 2 minute wall sits, 4 sets with 2 minutes rest between, done three times per week.

That’s 12 minutes of work.

If 2 minutes feels impossible at first, start shorter and build up. Make sure you're breathing throughout the exercise. Don't hold your breath.

Is it better than cardio?

The 2023 analysis suggests isometrics are better than other exercise types for lowering resting blood pressure on average, but that doesn’t make cardio or strength training irrelevant. The NHS still recommends at least 150 minutes per week of moderate physical activity for overall cardiovascular health [4].

In reality, the best approach is usually a combination of moving regularly, getting stronger, managing body weight, and sleeping well. Consider adding isometrics.

Bottom line

Based on current evidence, isometric exercises are among the most effective methods for lowering resting blood pressure.

They’re simple, time-efficient, and for many people, they’re pretty doable.

If you’ve been diagnosed with high blood pressure and you’re unsure what’s safe for you, speak to your GP first. If you’re cleared to train, a few wall sits each week might genuinely make a difference.
