Cardiovascular Fitness and Endurance

One of the biggest benefits of swimming is that it strengthens your cardiovascular system. Swimming involves using most of your major muscle groups all at once. This requires your heart to pump harder to deliver oxygenated blood throughout your body during your swim session leading to enhanced cardiovascular endurance.

Some of the cardiovascular benefits of regular swimming include:

Lower Blood Pressure

Studies show swimming just 30-60 minutes 2-3 times per week can help reduce blood pressure in people with hypertension. One study followed 35 people with high blood pressure who started a program swimming for 60 minutes 3 times a week.

After 12 weeks, they showed significant reductions in both systolic and diastolic blood pressure readings. The researchers attributed the improvements to a combination of the aerobic nature of swimming as an exercise and the cooling effects of being immersed in water.

Strengthens Heart

The increased workload on your heart during swimming causes it to expand and contract more efficiently. Over time this leads to increased stroke volume, which is the amount of blood pumped out of the heart with each beat.

One study had participants swim 45-60 minutes continuously at 60% intensity 3 times a week for 12 weeks. They measured significant increases in stroke volume and ejection fraction, which is the percentage of blood ejected from the heart during each contraction. These adaptations allow the heart to pump more blood with less effort.

Reduces Heart Disease Risk

One study found regular swimmers had a 41 percent lower risk of dying of heart disease and a 28 percent lower risk of death from any cause compared to inactive people.

Data collected from over 80,000 adults aged 20 and up in the course of 20 years concluded that swimming just 30 minutes per day provided substantial protection against coronary heart disease and stroke. The benefits were comparable to other types of aerobic exercise like walking and cycling.

The cardiovascular benefits apply to recreational and competitive swimmers of all ages and abilities. Swimming with proper pacing and intervals provides you with an excellent aerobic workout to strengthen your heart and cardiovascular system.

Improves Muscle Strength and Tone

The resistance provided by water makes swimming an ideal exercise for building muscle strength and tone throughout your entire body. The buoyancy also means your body is cushioned from strain or injuries.

Strengthening effects of swimming

When you swim, all your major muscle groups must work against the water’s drag with every stroke. This includes:

  • Arms and shoulders
  • Chest and back
  • Core muscles
  • Legs and glutes

Certain strokes/styles also focus on specific muscle groups:

  • Breaststroke works the arms, chest, and thigh muscles
  • Butterfly works the back, chest, shoulder, arm, and core muscles
  • Backstroke focuses on arm, shoulder, and core muscles
  • Freestyle works upper back, chest, shoulder, and arm muscles

Swimming laps and doing other pool exercises is an effective way to build lean muscle mass throughout your body. The consistent resistance pattern in swimming leads to defined arm, chest, shoulder, and leg muscles.

Having more muscle boosts your metabolism, supports joint health, and simply makes everyday activities easier.

Weight Loss

Vigorous swimming is an excellent calorie-burning exercise that helps with your weight management.

The amount of calories burned depends on your weight swimming pace and intensity.

  • A 160 lb person can burn over 400 calories per hour swimming moderate laps.
  • Faster, more vigorous swimming can burn upwards of 700 calories per hour for a 160 lb person.
  • Heavier swimmers burn more calories than lighter swimmers at the same swimming intensity.

Because swimming is a full-body aerobic activity, it stimulates your metabolism. It helps you build lean muscle mass that raises your resting metabolic rate so you burn more calories throughout the day.

The water provides a gentle resistance so heavier individuals and those new to exercise can still get in an effective workout to aid weight loss goals.

Research supports swimming for weight loss:

  • Studies show that regular lap swimming leads to reductions in body fat percentage and BMI measurements.
  • One study found that 16 weeks of swimming significantly decreased body fat and weight in overweight adults.


Combine swimming with a healthy diet, and you’ll be on your way to reaching your weight loss goals.
