What kind of exercise lowers high blood pressure the most?
The answer is clear. Combined aerobic plus resistance training produced the biggest drop in 24-hour systolic blood pressure, lowering it by 6.18 mm Hg in adults with hypertension. High-intensity interval training came in close behind at 5.71 mm Hg, and steady aerobic training alone dropped pressure by 4.73 mm Hg.
These numbers come from a network meta-analysis published in the British Journal of Sports Medicine. The researchers pulled together 31 randomized controlled trials covering more than 1,345 adults with high blood pressure. Across those trials, people tried 67 different exercise protocols, and each was tracked using 24-hour blood pressure monitoring. That kind of monitoring matters because it captures what your blood pressure actually does as you go about your day, not just the single reading a doctor catches in the office.
What the data show
The findings line up in a clear order. Combined training, which pairs cardio with strength work, gave the largest 24-hour systolic reduction at 6.18 mm Hg. HIIT, which alternates hard bursts with short rests, came next at 5.71 mm Hg. Steady aerobic training such as brisk walking, cycling, or jogging produced a 4.73 mm Hg drop. Those three approaches were the standouts.
The other options were weaker or less consistent. Resistance training on its own, isometric exercises, yoga, and pilates produced smaller or more variable effects on 24-hour blood pressure. That does not mean they are useless, but the evidence for lowering daily blood pressure is not as strong as it is for aerobic-based work.
Dr. Kumar’s Take
I find this analysis useful because it asks the right question. Most blood pressure studies use office readings, which only capture one moment in time. Twenty-four hour monitoring tells you what is happening while you sleep, while you commute, and while you are under stress at work, which is what actually drives heart and brain risk over the years. A 6 mm Hg drop in 24-hour systolic pressure is not a small number, it is in the same range as adding a blood pressure medication.
What I take from this is that you should not think of cardio and strength training as competing choices. The combined approach won. That fits with what I tell my patients, which is that a balanced program with both aerobic work and resistance training tends to outperform either one alone for overall health, not just blood pressure.
How the studies were done
A network meta-analysis is a statistical method that lets researchers compare many treatments at once, even when individual trials only tested two or three of them. By pooling data across 31 trials and 67 protocols, the authors could rank exercise modalities against each other rather than just asking whether exercise beats no exercise.
The trials all enrolled adults with hypertension and measured outcomes using ambulatory blood pressure monitoring, which uses a cuff that takes readings throughout the day and night. That is the strongest signal we have for cardiovascular risk, so the consistency of the design across studies adds confidence to the rankings.
Who benefits most
Adults already diagnosed with hypertension are the group these results apply to most directly. The trials enrolled people with elevated blood pressure, not healthy young athletes, so the findings translate well to a typical patient looking to lower readings without adding another pill or pushing an existing dose higher.
That said, the principle of using aerobic work as the backbone of an exercise plan is reasonable for anyone trying to protect their long-term heart health. The data simply happen to be strongest in the hypertensive population.
Practical Takeaways
- If you have high blood pressure and can only choose one approach, prioritize aerobic exercise such as brisk walking, cycling, or swimming, since it consistently lowers 24-hour blood pressure across trials.
- For the biggest drop in 24-hour systolic pressure, combine aerobic work with resistance training two or more days per week, since that pairing outperformed every other modality in this analysis.
- Consider HIIT if you are short on time and cleared by your doctor, since shorter sessions of high-intensity intervals produced nearly the same blood pressure benefit as longer combined workouts.
- Do not rely on yoga, pilates, or resistance training alone if lowering 24-hour blood pressure is your main goal, since those produced smaller and less consistent effects in the pooled data.

FAQs
How does a 6 mm Hg drop in blood pressure compare to taking medication?
A 6 mm Hg drop in systolic blood pressure is meaningful. In observational data, every 5 mm Hg reduction in systolic pressure is linked to roughly a 10 percent lower risk of major heart events over time. Most first-line blood pressure medications produce drops in the same general range when taken as a single agent. That does not mean exercise replaces medication for everyone, but it does mean the effect size from combined training is clinically real, not just statistical.
How often and how long should I exercise to get these blood pressure benefits?
The trials in this analysis used a wide range of protocols, but most active intervention groups exercised three to five days per week for sessions lasting 30 to 60 minutes, over periods of 8 to 16 weeks or longer. That lines up well with general public health guidance of about 150 minutes of moderate aerobic activity per week, with two or more days of resistance training added on. Consistency over months matters more than any single perfect session, and benefits tend to fade if you stop training.
Why is 24-hour blood pressure a better measure than a single doctor’s office reading?
Office readings only capture a snapshot, and they are often higher than your real average because of stress, recent caffeine, or what doctors call the white coat effect. A 24-hour monitor records dozens of readings as you work, eat, walk, and sleep, which gives a much better picture of your true blood pressure load. Cardiovascular risk tracks more closely with this 24-hour average than with office readings, so therapies that lower it, including exercise, are more likely to translate into fewer strokes and heart attacks down the road.
Bottom Line
If you have high blood pressure, the strongest evidence-based exercise prescription is aerobic work, either as steady cardio, HIIT, or combined with resistance training. Across 31 trials and more than 1,345 patients, combined aerobic and resistance training produced the biggest 24-hour systolic drop at 6.18 mm Hg, with HIIT and aerobic exercise close behind. Resistance, isometric, yoga, and pilates routines have their place in fitness, but they should not be your main strategy for lowering daily blood pressure.
