When people think about exercise for heart health, they usually think about walking, running, cycling or spending time on a cardio machine.

Strength training often gets treated as something separate. Something you do for bigger muscles, better performance or looking stronger.

I think that misses a large part of the picture.

Strength training is not a replacement for cardiovascular exercise. But it can be an important part of a well-rounded approach to cardiovascular health, including for people managing high blood pressure.

Recent systematic reviews continue to find reductions in resting and ambulatory blood pressure following resistance training, although the size of the benefit varies between studies and populations.

Your Heart Does Not Only Benefit From Cardio

Aerobic exercise deserves its reputation.

Walking, cycling, swimming and running can improve cardiovascular fitness and should form part of an active lifestyle.

But that does not mean resistance training has nothing to offer.

When you strength train regularly, you are challenging a large amount of muscle tissue. Your cardiovascular system has to support that work.

Over time, resistance training can contribute to improvements in several cardiovascular risk factors. One of the more interesting areas is blood pressure.

A 2025 meta-analysis of 14 randomised controlled trials involving people with hypertension found that resistance training reduced both systolic and diastolic blood pressure compared with control interventions. The exact size of the effect varied substantially between studies, so I would not promise someone a specific drop in their blood pressure from lifting weights.

A newer 2026 review reached a similar overall conclusion: resistance training reduced systolic and diastolic blood pressure in adults with hypertension or elevated blood pressure, while emphasising that it should complement rather than replace appropriate medical treatment.

That distinction matters.

Exercise is powerful, but it is not a reason to stop medication or ignore medical advice.

You Do Not Have to Choose Between Weights and Cardio

This is where I think people make exercise unnecessarily complicated.

They ask whether cardio or strength training is better.

In most cases, I would rather combine them.

Research in adults with hypertension has found that programmes combining aerobic and resistance training can reduce both systolic and diastolic blood pressure.

That makes practical sense too.

Aerobic training develops cardiovascular fitness.

Strength training develops muscle strength, physical capacity and your ability to produce force.

Those qualities overlap, but they are not identical.

Someone can have reasonable cardiovascular fitness and still struggle to carry groceries, get off the floor or maintain muscle as they age.

Likewise, somebody can be very strong while having poor aerobic fitness.

A good programme does not need to pick one side.

What Should Strength Training Actually Look Like?

For most people, I would keep it relatively simple.

You do not need a complicated bodybuilding split or six gym sessions every week.

A programme could include a squat or sit-to-stand variation, a hinge such as a deadlift variation, pushing, pulling, some single-leg work and loaded carries.

The exercises themselves are less important than having a programme you can perform consistently and progress appropriately.

The American College of Sports Medicine recommends resistance exercise around two to three days per week as part of exercise programming for people with hypertension.

That is a very manageable starting point for most people.

If you are new to training, you also do not need to begin with extremely heavy weights. Building good movement, confidence and tolerance to resistance comes first.

Then the load can increase as you become stronger.

But Doesn’t Lifting Weights Increase Blood Pressure?

During resistance exercise, blood pressure temporarily increases.

That is a normal physiological response to exercise.

The fact that blood pressure rises during a set does not mean regular resistance training automatically causes chronically higher resting blood pressure.

The longer-term evidence points in the opposite direction. A 2025 systematic review examining 24-hour ambulatory blood pressure found reductions following chronic resistance training, particularly in people with chronic health conditions.

There is still an important safety consideration here.

If you have uncontrolled hypertension, cardiovascular disease, unexplained chest symptoms or another significant medical condition, I would not recommend simply starting a demanding strength programme without appropriate medical guidance.

Your starting point matters.

So does how you breathe, how hard you train, what exercises you choose and how quickly you progress.

Strength Also Matters as You Get Older

Heart health is not the only reason I want people to maintain strength.

We also lose muscle and strength as we age if we do nothing to challenge them.

That affects everyday life.

Carrying bags becomes harder. Stairs become more demanding. Getting up from low positions requires more effort. Your reserve for illness, injury and periods of inactivity becomes smaller.

This is why I do not view strength training as something reserved for athletes or younger people.

It is part of maintaining physical capacity.

There is also evidence in older adults that resistance-based programmes can improve blood pressure alongside body composition and other measures of cardiovascular health.

The goal is not simply to lift heavier weights.

It is to remain capable.

Build a Programme You Can Keep Doing

You do not need to turn every session into a cardiovascular test.

You also do not need to train until exhaustion for strength training to count.

Start with a level that matches your current ability.

Train consistently.

Progress gradually.

Keep some aerobic activity in your week as well.

And if you have diagnosed hypertension or cardiovascular disease, make sure your training fits alongside the management plan from your doctor or healthcare team.

For most people, the question should not be whether they should do cardio or strength training.

The better question is how to include enough of both.

That gives you a far more complete approach to staying fit, strong and physically capable over the long term.
