Exercise for Heart Health: Cardio, Strength and Blood Pressure

World Heart Day falls on 29 September. This week is a useful opportunity to think about exercise for heart health beyond step counts and calorie totals.

A manageable movement routine can support health, while blood pressure checks help you understand something a workout tracker cannot tell you.

You do not need to begin with an exhausting session. The more useful starting question is: which activity can you repeat comfortably, and what support would make it easier to keep going?

What does exercise research tell us about blood pressure?

A 2023 review combined 270 randomised trials involving 15,827 participants. Eligible programmes lasted at least two weeks and included a non-exercise control group. Its pooled differences in resting blood pressure were:

Source: Edwards et al., British Journal of Sports Medicine, 2023. Negative values indicate lower resting pressure relative to controls. Systolic is the upper number; diastolic is the lower number.

These are group averages across different trials, not individual predictions or a single head-to-head test. They do not show what one workout will do, or establish a corresponding percentage reduction in heart attacks. The study is established evidence, not a new 2026 discovery.

Choose a routine you can actually repeat

It is tempting to turn a table into a shopping list: pick the biggest number, then copy that exercise. A more useful approach is to build a routine around your current ability, preferences and any medical advice you have received.

Give aerobic activity a place in the week

Walking, cycling and other aerobic activities offer different ways to get moving. The Heart Foundation describes moderate effort as breathing more heavily while still being able to hold a conversation. If you have been inactive, start gently and build gradually.

Make the plan concrete. Choose a route, a convenient time and a backup for wet weather. A walk with a friend, an indoor session or a trip to the gym may each fit a different day. These are planning suggestions, not a tested treatment programme.

Include strength work with appropriate support

Resistance exercise can use weights, bands or body weight. Ask for help choosing suitable movements and learning technique if you are new to it. Breathe normally rather than holding your breath during lifts, as the Heart Foundation advises.

Look beyond the gym session

Australia's current guidance for adults aged 18–64 recommends 30 minutes or more of moderate-to-vigorous activity on most days, strengthening on at least two days per week, and mobility, balance and coordination activities on at least three days. It also encourages daily light activity, regular breaks from prolonged sitting, and seven to nine hours of sleep with consistent timing.

These are general population recommendations, not a personal prescription for someone with heart disease. Different guidance and adaptations apply to some groups, including older adults and people with chronic conditions.

Choose an accessible way to get moving

Walking is one option; cycling, swimming or a suitable exercise class may fit you better. Start with an activity you know how to access and a time you can protect.

For example, you might try a brief walk after lunch rather than waiting for a completely free evening. Treat that as a starting point you can build on, not a prescribed dose for preventing dementia.

Three decisions to make this week

1. Pick your repeatable activity. Choose an accessible option you are willing to return to, rather than the workout that looks most impressive online.

2. Make space for support. Write down a question about equipment, technique or exercise suitability before your next appointment or gym visit.

3. Review what worked. At the end of the week, consider the timing, setting and difficulty. Adjust the next week's plan instead of treating one missed session as failure.

Know your blood pressure, not just your fitness score

High blood pressure can have no obvious symptoms. Feeling fit or completing a hard workout does not confirm that your pressure is healthy. The Heart Foundation recommends regular checks with a health professional; some people also need medication.

Ask your GP whether a blood pressure check or broader heart-health assessment is appropriate for you. If you have been asked to measure at home, follow the recommended method and discuss the results with your clinician. Do not stop or change prescribed medication because you have started exercising.

When exercise needs medical advice

If you have an existing health condition, ask your doctor about a suitable starting point. Stop activity and seek medical advice for chest discomfort, feeling faint, difficulty breathing or an unusually fast or irregular heartbeat. If you suspect a heart attack, call Triple Zero (000) immediately.

Find a practical starting point locally

If you would like general fitness support, explore Wellness Department's Hurstville and Liverpool gymsand enquire about getting started. Bring any exercise advice from your healthcare team so you can discuss what is appropriate. A gym session does not replace blood pressure assessment or clinical care.

Frequently Asked Questions

Is cardio the only exercise that can help blood pressure?

No. The review above reported reductions with several exercise types, including resistance training. It does not identify the right programme for every reader.

Should everyone start wall sits because isometric exercise had the largest number?

No. A pooled average is not a universal prescription. Suitability and an appropriate exercise dose require more than choosing the highest-ranked result.

Do I have to join a gym?

No. Everyday movement and walking can be part of an active routine. A gym is one setting that may provide equipment and support you find useful.

Can exercise replace blood pressure medicine?

Do not make that change yourself. Your clinician should review your readings and treatment needs; lifestyle changes and medication may both be needed.

Evidence Summary

• Randomised-trial synthesis: supports reductions in resting blood pressure with training; individual responses and trial protocols vary.

• Australian movement guidance: provides population targets, not a hypertension treatment protocol.

• Heart Foundation guidance: supports gradual activity, blood pressure checks and appropriate clinical advice.

• World Heart Day: supplies the timely context, not evidence for an exercise effect.
