What to Know Before Starting a Cardio Routine for High Blood Pressure

If you have high blood pressure, your doctor may have already told you to move more, and for good reason. “Exercise is probably the most effective lifestyle intervention for lowering blood pressure,” says Fred Watson, MD, FACC. Studies suggest that regular aerobic activity can lower systolic blood pressure, which can significantly reduce your risk of heart disease and stroke over time. “Aerobic exercise helps blood vessels relax and function more efficiently,” says Adedapo Iluyomade, MD, MBA, FACC.

Walking and running are accessible ways to get more aerobic exercise. But before you start, you need to know how much activity to aim for, how to start safely, and when to talk with your doctor. Here’s what to keep in mind.

1. Some people should get medical clearance first

Before donning, it’s helpful to know if you need a doctor’s approval first. “Be cleared first if you have known heart disease, chest symptoms, or are very deconditioned,” says Tisa Saha, MD, FACC. Starting an exercise routine when your high blood pressure is already putting strain on your heart and arteries can carry real risks. Pushing too hard and too fast without knowing where your baseline is can trigger a cardiac event in people with underlying conditions.

You should also consult your doctor if your blood pressure is very high or poorly controlled. Your doctor can help you decide on a safe starting point. They can also suggest ways to adapt your plan for other conditions, such as diabetes or joint problems.

2. Walking counts

Intensity isn’t everything. “Don’t underestimate walking, just because it seems less intense than running. For controlling blood pressure, the best exercise is usually one that you can do safely and regularly week after week,” says Iluyomade.

Running can be a good choice if your body tolerates it and you enjoy it. But brisk walking also counts as moderate aerobic activity. For many people, it’s easier on the joints and easier to integrate into daily life.

3. Start Slow and Build Up Gradually

The goal for the first few weeks is progress, not performance. “Start slowly and gradually increase speed and distance. Aim for a moderate level of effort; you should be able to complete a sentence or hold a conversation while you walk. Start with 10 minutes a day and add a few minutes each week,” says Watson. This “conversation test” is a useful tool. If you’re too out of breath to speak in full sentences, slow down.

4. Aim for 150 minutes per week plus strength training

“Aim for 150 minutes per week of moderate aerobic/cardio zone 2 activity (e.g., brisk walking) plus strength work/resistance training over two or more days for optimal results,” says Watson.

This works out to about 30 minutes a day, five days a week, but you can break it up into shorter sessions. When adding strength training, breathe regularly throughout each movement.

5. Exercise Works Alongside Medication

If your doctor has prescribed medication, continue taking it. “Exercise complements, rather than replaces, medications when they are needed,” says Iluyomade.

Continue to take your medications as prescribed unless your doctor tells you otherwise. Certain medications can also change the way your body responds to exercise. Beta blockers, for example, can keep your heart rate lower than usual. This makes heart rate zones less reliable, so the talk test may be a better guide.

6. Know when to stop

Pay attention to how you feel during each workout. Stop and seek medical attention if you experience chest pain or pressure, dizziness, fainting, unusual shortness of breath, or irregular heartbeat. Warming up for five to ten minutes and then cooling down can also help. This gives your heart rate and blood pressure time to gradually increase and decrease.

Tips for sticking to your routine

• Plan your workouts. Mark walks on your calendar like any other appointment. A set time, like after breakfast or during your lunch break, makes it easier to maintain this habit.
• Track your progress. Log your minutes, distance or steps in an app or laptop. If your doctor recommends it, you can also check your blood pressure at home and share the results during your next visit.
• Find a walking partner. A friend, family member, or walking group can make workouts more fun. Having someone counting on you also makes it harder to take the plunge.
• Change your route. Try a new park, trail, or neighborhood when your usual path gets boring. Variety can help you stay motivated.
• Set small, realistic goals. Focus on adding a few minutes each week instead of chasing big leaps. Small victories add up and help you build confidence.
• Plan for bad weather. Have a backup, such as a treadmill, indoor track, or mall. This way, rain or heat won’t derail your week.

Our expert opinion

Walking and running can be powerful tools for managing high blood pressure, but they work best when you treat them as a long-term habit. Start with short, moderate sessions and gradually increase. Try to do 150 minutes of aerobic activity per week and add strength training for at least two days. If you have heart disease, worrying symptoms, or very high blood pressure, talk to your doctor before starting. Continue to take all prescribed medications and remember that exercise works best as part of a larger plan. You don’t need to run fast or far to progress. The routine that helps the most is the one you can follow, week after week.
