A new analysis suggests that the best exercise for lowering blood pressure is not one single magic move. For adults with hypertension, aerobic exercise, combined aerobic and strength training, and high-intensity interval training, known as HIIT, were linked to meaningful drops across a full day and night.
That is the part that stands out. The researchers did not look only at a quick reading in a doctor’s office. They focused on blood pressure measured during real life, while people moved, worked, rested, and slept.
Why 24 hours matters
Hypertension means blood pressure stays too high over time. In the United States, high blood pressure is generally defined as readings that stay at or above 130 over 80, and the CDC says nearly half of U.S. adults meet that definition.
Those two numbers are not just medical trivia. The top number, called systolic pressure, shows the force when the heart pushes blood out. The lower number, called diastolic pressure, shows the pressure between beats.
The Brazilian team used evidence based on ambulatory blood pressure monitoring. That is a portable device that checks pressure again and again over 24 hours, usually every 15 to 30 minutes.
It gives a fuller picture than one nervous moment in a clinic chair, and ambulatory systolic readings have been reported to track mortality risk more closely than office readings.
What the researchers compared
The study was carried out by Vinícius Mallmann Schneider, Patrícia Klarmann Ziegelmann, Dalva Muniz Pereira, and Rodrigo Ferrari, from the Federal University of Rio Grande do Sul in Porto Alegre, Brazil.
Their goal was simple, even if the statistics were not. Which kind of structured exercise does the most for blood pressure across a normal day?
To answer that, the team reviewed 31 randomized clinical trials involving 1,345 adults with hypertension. Randomized trials are studies where people are assigned to groups by chance, which helps make the comparison fairer.
The researchers compared eight exercise types. They included continuous aerobic exercise, combined aerobic and resistance training, HIIT, weight training, isometric exercise, Pilates, yoga, and recreational sports.
The exercises that stood out
For systolic pressure, combined training produced the largest average drop, a little more than 6 millimeters of mercury over 24 hours. HIIT followed closely, with a drop of almost 6 points, while aerobic exercise lowered it by nearly 5 points.
For diastolic pressure, HIIT had the strongest signal, lowering the lower number by nearly 5 points. Pilates, combined training, and aerobic exercise also showed meaningful decreases.
So what counts as aerobic exercise? Think brisk walking, cycling, swimming, jogging, or other steady movement that gets the heart working. It is the kind of activity many people can picture fitting into a week, even if it starts with a short walk around the block.
What this means in real life
In practical terms, the results point toward movement that keeps the heart and blood vessels working for more than a few seconds. A brisk walk, a bike ride, or a swim may not look dramatic, but the effect can linger after the workout is over.
Combined training means pairing that kind of cardio with strength work, such as weights, resistance bands, or body-weight exercises. HIIT is different. It alternates short, hard bursts of effort with easier recovery periods, which can feel intense quickly.
Does that mean everyone with high blood pressure should jump into sprints tomorrow morning? Not quite.
The American Heart Association says healthy adults usually do not need medical clearance before becoming active, but adults with chronic or other conditions should talk with a health professional about any limits.
The fine print matters
The study also found limits. Weight training alone and isometric exercise, such as holding a wall sit or squeezing a handgrip, did not show statistically significant 24-hour ambulatory blood pressure reductions in this analysis.
That may sound surprising because previous research in the same journal found strong results for isometric exercise when blood pressure was measured at rest or in office-style settings. The difference is important. One snapshot is not the same as a full day.
The researchers also urged caution with yoga, Pilates, and recreational sports. Some results looked promising, but the available studies were small, and the overall certainty of the evidence was low or very low for many comparisons.
Exercise is not a side note
Margarita Morales, a cardiologist with the Argentine Society of Hypertension and the Hospital Italiano de Buenos Aires, told Infobae that “physical activity is one of the essential components in preventing and treating cardiovascular disease.
It has also been shown to reduce systolic and diastolic blood pressure levels in patients with hypertension.”
That message fits the new findings, for the most part. Exercise is not a replacement for medical care, and it is not the only lever that matters. Diet, sleep, stress, medication, and follow-up visits still count.
But the study gives doctors and patients a more useful map. At the end of the day, the best starting point may be the kind of exercise that moves the heart consistently and can be repeated week after week.
The main study has been published in the British Journal of Sports Medicine.
