In short:
- Regular aerobic training lowers systolic blood pressure by an average of 5–8 mmHg (Cornelissen & Smart, 2013).
- The effect appears even at a moderate training load and lasts as long as you keep exercising.
- The strongest evidence is for endurance training, but strength training and isometric training help too.
- People whose blood pressure is elevated to begin with benefit the most.
How are training and blood pressure related?
The link between training and blood pressure is one of the best-studied in all of public health: regular physical activity lowers both systolic (upper) and diastolic (lower) blood pressure by a measurable amount. This overview explains why exercise lowers blood pressure, how big the effect is and which kind of training is worth prioritizing.
Blood pressure arises when the heart pumps blood into the blood vessels, and it depends on two factors: the amount of blood the heart pumps out and the resistance of the blood vessels. Training affects both. Regular exercise improves the function of the inner lining of the blood vessels (the endothelium), increases nitric oxide production and reduces excessive activity of the sympathetic nervous system — all of these changes lower vascular resistance and therefore blood pressure (Cornelissen & Fagard, 2005).
How much does training lower blood pressure?
The largest body of evidence comes from meta-analyses that pool hundreds of randomized trials. Aerobic endurance training lowers systolic blood pressure by an average of about 5–8 mmHg and diastolic blood pressure by 2–4 mmHg (Cornelissen & Smart, 2013). An earlier large review found a similar magnitude — a systolic drop of roughly 3.8 mmHg and a diastolic drop of 2.6 mmHg (Whelton et al., 2002).
These figures may seem modest, but at the public health level they matter: a drop in systolic blood pressure of just 5 mmHg noticeably reduces the risk of stroke and heart disease. The greatest benefit goes to people whose blood pressure is elevated to begin with — in people with hypertension, the drop often exceeds 8 mmHg (Cornelissen & Smart, 2013).
The World Health Organization recommends that adults do at least 150–300 minutes of moderate aerobic activity per week; for more detailed guidance, see the WHO physical activity recommendations. This amount is enough to have a measurable effect on blood pressure.
Which training lowers blood pressure best?
The strongest evidence base belongs to aerobic endurance training — walking, running, cycling, swimming. In addition, dynamic strength training also supports lower blood pressure: a meta-analysis found that as a stand-alone intervention it lowers systolic blood pressure by roughly 3 mmHg (MacDonald et al., 2016). Isometric training (e.g. static handgrip squeezing) is also surprisingly effective, and some reviews have found an even larger drop (Carlson et al., 2014).
In practice, you don’t have to pick just one form. A varied approach that combines endurance and strength elements supports both blood pressure and overall health. If you’re curious how different types of training affect the body, take a closer look at what functional training is and how plyometric training works. The broader metabolic benefits of exercise — for example fat burning and training — go hand in hand with improved blood pressure, because improvements in body weight and body composition also reduce the workload on the heart. Training also affects the hormonal background, which you can read about in the article testosterone and training.
How quickly does the effect appear, and how long does it last?
The blood-pressure-lowering effect of training has two parts. First, a temporary drop appears after a single workout and can last several hours — this is called post-exercise hypotension. Second, over a period of weeks a more lasting adaptation develops, which shows up in resting blood pressure (Pescatello et al., 2004). Measurable changes usually appear within 4–12 weeks of consistent training.
It’s important to understand that the effect lasts only as long as you keep exercising. If you stop training, blood pressure returns to its previous level within a few weeks. That is why consistency matters more than the intensity of individual workouts.

Frequently asked questions
How much does training lower blood pressure?
Regular aerobic training lowers systolic blood pressure by an average of 5–8 mmHg and diastolic blood pressure by 2–4 mmHg, often more in people with elevated blood pressure (Cornelissen & Smart, 2013).
Which type of training is best for blood pressure?
The strongest evidence is for aerobic endurance training (walking, running, cycling, swimming), but dynamic strength training and isometric training also help lower blood pressure.
How long does it take for training to affect blood pressure?
A single workout produces a temporary drop lasting a few hours; a more lasting effect usually develops over 4–12 weeks of consistent training.
Will the drop in blood pressure last if I stop training?
No. The effect lasts only as long as you keep exercising; if you stop training, blood pressure returns to its previous level within a few weeks.
How much should I exercise per week?
The WHO recommends that adults do at least 150–300 minutes of moderate aerobic activity per week, which is enough to have a measurable effect on blood pressure.
