Isometric Exercise for Cardiovascular Health

Regular exercise is important for maintaining good cardiovascular health, but did you know that there are different types of exercises that can benefit your heart?  I want to  introduce you to isometric exercise, which is a lesser-known type of exercise that can have benefits for your cardiovascular health. Even if you haven’t had any issues with your heart in the past, incorporating isometric exercises into your fitness routine can be a great way to support your heart health and overall well-being.

Benefits of Exercise for Cardiovascular Health

Before we dive into isometric exercise, let’s talk about the benefits of exercise for cardiovascular health in general. 

Exercise is one of the most effective ways to improve and maintain heart health. Regular physical activity can lower blood pressure, improve cholesterol levels, reduce the risk of type 2 diabetes, and improve circulation. It can also reduce the risk of heart disease, stroke, and other cardiovascular conditions.

One of the main ways that exercise benefits cardiovascular health is by improving the function of the heart and blood vessels. When you exercise, your heart beats faster and harder, which helps to strengthen the heart muscle. 

Exercise also increases blood flow, which helps to improve circulation and deliver oxygen and nutrients to the body’s tissues.

Another way that exercise benefits cardiovascular health is by reducing the risk of other conditions that can contribute to heart disease, such as high blood pressure, high cholesterol, and type 2 diabetes. 

Regular exercise can also help with weight management, which is important for reducing the risk of heart disease and other conditions.

Overview of Isometric Exercise

Isometric exercise can be a great addition to your cardiovascular exercise routine.

It can help to improve muscular strength and endurance, which can in turn improve cardiovascular health. Isometric exercise can also be helpful for people who have joint pain or other limitations that prevent them from doing more traditional forms of exercise.

Definition of Isometric Exercise

Isometric exercise is a type of strength training where the muscle is contracted without any movement. The word isometric is derived from two Greek words: iso, which means same, and metric, which means length. During isometric exercises, the muscle contracts and produces tension, but the length of the muscle remains the same.

Types of Isometric Exercises

There are various types of isometric exercises, each targeting different muscle groups. Some of the most common types include:


Planks are a popular isometric exercise that targets the core muscles. This exercise involves holding a push-up position, with the arms extended and the body in a straight line. The core muscles are engaged to keep the body in a stable position.

Wall Sits

Wall sits are another common isometric exercise that targets the lower body. This exercise involves leaning against a wall with the feet shoulder-width apart and the knees bent at a 90-degree angle. The leg muscles are engaged to hold the body in a seated position.

Hand Grip Exercises

Hand grip exercises involve squeezing a hand gripper or a small ball in your hand for a certain period. This exercise targets the muscles in the forearm and can help improve grip strength.

Plie Squats

Plie squats are a variation of squats that target the inner thighs. This exercise involves standing with your feet wider than shoulder-width apart and toes pointing outwards. The knees are then bent to a 90-degree angle and held in that position for a certain period.

How Isometric Exercise Differs from Traditional Aerobic Exercise

While traditional aerobic exercise, such as running, cycling, or swimming, is focused on increasing heart rate and improving cardiovascular health by getting the heart and lungs working harder, isometric exercise targets individual muscles without increasing the heart rate. 

In contrast to aerobic exercise, isometric exercise is focused on developing strength, endurance, and improving flexibility. 

Unlike traditional exercise, isometric exercises are typically low impact and can be performed almost anywhere, with no need for specialized equipment.

Isometric exercises can be a great way to add variety to your workout routine and help you break through a plateau. 

Evidence Supporting the Benefits of Isometric Exercise for Cardiovascular Health

Several studies have demonstrated the benefits of isometric exercise for cardiovascular health. One study found that isometric exercise can significantly lower blood pressure in individuals with hypertension. 

Another study showed that isometrics helped develop the heart muscle in athletes and could possibly be used as part of a supervised exercise training program for those with impaired heart function.

In addition, a study found that isometric exercise can be an effective way to increase muscular strength, which is important for maintaining cardiovascular health. 

Comparison of the Benefits of Isometric Exercise versus Traditional Aerobic Exercise

While both isometric exercise and traditional aerobic exercise have been shown to have positive effects on cardiovascular health, they target different aspects of fitness. Aerobic exercise focuses on increasing endurance by improving the cardiovascular system’s ability to transport oxygen to the muscles being worked. Isometric exercise, on the other hand, focuses on increasing strength and endurance by holding a static muscle contraction.

Isometric exercise has been shown to be particularly effective for individuals who are unable to perform traditional aerobic exercise due to injury, illness, or mobility issues. For example, individuals with osteoarthritis may find it difficult to perform high-impact aerobic exercises like running or jumping, but they can still benefit from isometric exercises that do not place stress on the joints.

Isometric Exercise for Specific Populations

Isometric Exercise for Athletes

Isometric exercise has been shown to be beneficial for athletes looking to improve their strength and endurance. Isometric exercises can be used to target specific muscle groups, such as the quadriceps, biceps, and abdominals, which are important for many athletic activities.

Isometric Exercise for Older Adults

Isometric exercise can also be beneficial for older adults looking to maintain their strength and mobility. As we age, our muscles can weaken, which can lead to a loss of balance and an increased risk of falls. Isometric exercises can help to improve muscle strength and balance, which can reduce the risk of falls and improve overall mobility.

Isometric Exercise for Individuals with Cardiovascular Disease

Isometric exercise may be beneficial for individuals with cardiovascular disease. Isometric exercises can improve cardiovascular health by helping to develop the heart muscle.

Isometric Exercise for Individuals with Hypertension

As we have previously outline, isometric exercise can have a positive effect on those individual’s suffering from high blood pressure.

Precautions for Isometric Exercise

To reduce the risk of injury and ensure a safe and effective isometric exercise program, there are several precautions that should be taken:

  • Always warm up before beginning isometric exercises. This can include light aerobic exercise or dynamic stretching to help prepare the muscles for the static contractions of isometric exercises.
  • Use proper form when performing isometric exercises. This can include maintaining proper alignment, keeping the core engaged, and avoiding overexertion.
  • Gradually increase the intensity and duration of isometric exercises. It’s important to start with easier exercises and gradually increase the difficulty over time to avoid injury and overexertion.
  • Individuals with hypertension or other cardiovascular conditions should consult with a healthcare professional before beginning an isometric exercise program and monitor their blood pressure regularly during and after exercise.

Frequently Asked Questions

What are the best isometric exercises for cardiovascular health?

Isometric exercises can target many different muscle groups in the body. However, when it comes to cardiovascular health, the best isometric exercises are those that work the large muscle groups in the lower body, such as the thighs, glutes, and calves. These exercises include:

  • Wall sits: Stand with your back against a wall and lower your body down until your thighs are parallel to the floor.
  • Planks: Get into a push-up position, but instead of lowering yourself to the ground, hold yourself up on your forearms and toes.
  • Squats: Stand with your feet shoulder-width apart and lower your body down as if you were sitting in a chair, hold this position.
  • Lunges: Step forward with one foot and lower your body down until both knees are bent at a 90-degree angle, hold this position.  Swap legs and repeat.
  • Calf raises: Stand with your feet shoulder-width apart and raise up onto your toes, and hold this position.

How often should I perform isometric exercises?

The frequency of your isometric exercise routine will depend on your fitness goals and current fitness level. If you’re new to isometric exercise, it’s best to start with just a few exercises a day, a few times a week. As you become more comfortable with the exercises, you can gradually increase the frequency and duration of your workouts.

Can isometric exercise lower blood pressure?

Yes, studies have shown that isometric exercise can be an effective way to lower blood pressure, particularly in individuals with hypertension. However, it’s important to talk to your healthcare provider before starting an isometric exercise routine if you have high blood pressure or any other cardiovascular conditions.

Is isometric exercise safe for pregnant women?

Isometric exercise can be safe for pregnant women, but it’s important to talk to your healthcare provider before starting any exercise routine during pregnancy.

Can isometric exercise replace traditional aerobic exercise?

While isometric exercise can be an effective way to improve cardiovascular health, it’s not a replacement for traditional aerobic exercise. Aerobic exercise, such as walking, jogging, or cycling, provides a different set of benefits for the body, such as increased heart rate, improved lung function, and increased calorie burn.

Ideally, a well-rounded fitness routine should include both isometric and aerobic exercise. By combining these two types of exercise, you can improve your overall health and fitness, reduce your risk of chronic diseases, and enhance your quality of life
