Swimming and running as full-body workouts continues to be a popular topic. Both activities offer a plethora of health benefits, but they differ significantly in terms of impact, muscle engagement, and overall effectiveness. We’ll delve into the effects of swimming and running on these three factors, exploring the advantages and disadvantages of each activity to help you make an informed decision based on your fitness goals and preferences.

1. Cardiovascular Benefits

Running and swimming are both excellent cardiovascular exercises that can enhance heart health and stamina. Running is a weight-bearing exercise that helps strengthen bones and muscles, improving overall cardiovascular fitness.

On the other hand, swimming is a non-weight-bearing exercise, making it gentler on the joints and ideal for individuals with joint issues. The buoyancy of water reduces impact stress, making swimming an excellent choice for those looking for a low-impact cardiovascular workout.

2. Muscle Engagement

While both activities engage various muscle groups, they differ in terms of which muscles are primarily targeted. Running is renowned for working the lower body muscles, including the quadriceps, hamstrings, calves, and glutes. It also engages the core muscles to a certain extent. On the contrary, swimming involves a more comprehensive muscle engagement, working the upper body, lower body, and core simultaneously. The resistance provided by water requires the use of multiple muscle groups, resulting in a well-rounded full-body workout.

3. Impact on Joints

Joint impact is a crucial consideration, especially for individuals with pre-existing joint conditions or those prone to injuries. Running, being a weight-bearing exercise, can exert significant stress on the joints, particularly the knees and ankles. In contrast, swimming is a low-impact activity that minimizes stress on the joints, making it an excellent choice for individuals with arthritis or joint pain. The buoyancy of water reduces the risk of injury and provides a gentle workout environment.

4. Caloric Burn

The caloric burn associated with running and swimming vary depending on factors such as intensity, duration, and individual fitness levels. Running is often considered a high-intensity exercise that will lead to a rapid calorie burn, making it effective for weight management and fat loss.

Swimming, while also providing an efficient calorie burn, may not be as intense as running. However, the longer duration of swimming sessions often compensates for this, resulting in a comparable overall caloric expenditure. The longer you swim the more calories you will burn which is how swimming can help you lose fat.

5. Mental Health Benefits

Beyond the physical aspects, both swimming and running offer mental health benefits. Running is often praised for its stress-relieving and mood-enhancing effects, thanks to the release of endorphins – the body’s natural feel-good hormones. Similarly, swimming can have a calming effect, providing a sense of relaxation and tranquility. The rhythmic nature of swimming, combined with the soothing properties of water, contribute to reduced stress levels and improved mental well-being.

Is Swimming or Running Better For a Full-Body Workout?

Swimming is generally considered to be a more comprehensive full-body workout compared to running. While running primarily engages the lower body muscles, such as the quadriceps, hamstrings, calves, and glutes, it doesn’t involve the upper body to the same extent. Swimming recruits muscles from both the upper and lower body simultaneously, making it a more holistic exercise.

Here’s how swimming targets various muscle groups across the body:

  1. Upper Body: Freestyle, backstroke, breaststroke, and butterfly strokes in swimming involve significant arm and shoulder movements. These strokes engage the muscles in the chest, back, shoulders, and arms, providing a thorough workout for the upper body.
  2. Core: Swimming requires a strong and engaged core to maintain proper body position and balance in the water. The constant stabilization works the muscles in the abdomen and lower back.
  3. Lower Body: The kicking motion in swimming, especially in strokes like freestyle and breaststroke, targets the muscles in the legs, including the quadriceps, hamstrings, and calves.
  4. Cardiovascular System: Swimming also provides an excellent cardiovascular workout as it elevates the heart rate and promotes efficient circulation, benefiting the entire cardiovascular system.

In contrast, running primarily emphasizes the muscles in the legs and to a lesser extent, the core. It is a great workout for lower body strength and cardiovascular health, but it doesn’t engage the upper body to the same degree as swimming.

If your goal is to work multiple muscle groups simultaneously and achieve a well-rounded, full-body workout, swimming is an excellent choice. The resistance provided by water adds an extra challenge, promoting muscle endurance and toning throughout the body.



The choice ultimately depends on your individual preferences, fitness goals and any existing health considerations. Running offers a high-impact, intense workout that targets specific muscle groups. This makes it a great option for those seeking weight-bearing exercise. On the other hand, swimming provides a low-impact, full-body workout with the added benefit of joint-friendly movements.

The key to a successful fitness routine lies in finding an activity that you enjoy and can sustain over the long term. Whether you choose to lace up your running shoes or dive into the pool, both swimming and running will contribute to improved cardiovascular health, enhanced muscle strength, and overall well-being. Consider incorporating a mix of both activities into your routine for a well-rounded and enjoyable approach to fitness.
