Staying active becomes increasingly important with age, but traditional forms of exercise are not always comfortable or practical for older adults. Walking can sometimes aggravate painful joints, while running and high-impact workouts may place too much stress on the knees, hips, ankles, or back.
That is one reason pool-based exercise has become a popular option for older adults.
Two of the most common choices are swimming and water aerobics. Both can provide cardiovascular exercise, help improve endurance and muscle fitness, and allow you to exercise with less impact than many land-based activities. However, they are very different workouts.
So, which is better for older adults: swimming or water aerobics?
The answer depends on your swimming ability, fitness goals, joint comfort, confidence in the water, and the type of exercise you enjoy enough to do consistently.
Why Exercise in the Water?
Water provides two important advantages: buoyancy and resistance.
Buoyancy supports part of your body weight, reducing stress on weight-bearing joints. At the same time, water provides resistance as you move your arms and legs. This allows you to work your muscles without necessarily using heavy weights.
Mayo Clinic describes aquatic exercise as a low-impact activity that can reduce pressure on bones, joints and muscles while providing natural resistance that can help improve muscular strength and endurance. It can also be useful for older adults and people who experience joint discomfort. (Mayo Clinic News Network)
The CDC also lists both swimming and water aerobics as examples of aerobic activities suitable for older adults. (CDC)
The important question is not whether one is universally better. Instead, it is about which option matches your needs.
Swimming for Older Adults
Swimming involves moving through the water using specific strokes such as freestyle, breaststroke, backstroke or sidestroke.
Unlike simply exercising in shallow water, swimming requires you to support yourself in the water and coordinate breathing, arm movements and kicking.
Benefits of Swimming
Swimming can provide a full-body aerobic workout. Your arms, legs, shoulders, back and core all contribute to movement through the water.
Regular swimming may help:
- Improve cardiovascular fitness
- Build muscular endurance
- Improve coordination
- Increase overall stamina
- Support mobility
- Provide a low-impact alternative to some land-based exercises
- Promote relaxation and mental well-being
Swimming can also be an excellent option for someone who already knows how to swim and enjoys independent workouts.
Mayo Clinic notes that swimming can keep the heart rate elevated while developing muscle strength and can be beneficial for cardiovascular fitness and core strength. (Mayo Clinic Orthopedics)
Swimming May Require More Skill
One limitation is that swimming is a skill-based activity.
An older adult who has not been in a pool for many years may find that swimming laps is surprisingly tiring. Even someone who learned to swim decades ago may have lost confidence or technique.
Breathing can also become a challenge. Trying to swim continuously while coordinating breathing, kicking and arm movements may result in fatigue much faster than expected.
That does not mean swimming is unsuitable. It simply means beginners and returning swimmers should start gradually.
What Is Water Aerobics?
Water aerobics is a broader category of exercise performed in a swimming pool. Classes may involve walking, marching, leg lifts, arm movements, kicks, squats, jogging movements and other exercises.
Many classes take place in waist- to chest-deep water, meaning participants do not necessarily need to swim.
This is one of the biggest differences between swimming and water aerobics.
Mayo Clinic notes that aquatic exercise does not necessarily require swimming ability because many exercises can be performed while standing in shallow water. (Mayo Clinic News Network)
Water aerobics can therefore be particularly appealing to older adults who are uncomfortable swimming laps or who simply prefer instructor-led exercise.
Benefits of Water Aerobics
Water aerobics can provide a combination of aerobic conditioning, resistance exercise, mobility work and balance challenges.
Depending on the class, it may help improve:
- Cardiovascular endurance
- Muscular endurance
- Flexibility
- Range of motion
- Coordination
- Balance
- General physical fitness
The water itself provides resistance in multiple directions, so movements that seem easy on land can become more challenging in the pool.
Another advantage is variety. A class may include several different exercises during one session instead of repeating the same swimming stroke for 30 or 45 minutes.
Swimming vs Water Aerobics: Which Is Easier?
For many older beginners, water aerobics is easier to start with.
You can usually stand in the pool, follow the instructor and control the intensity of your movements. You do not have to coordinate swimming strokes or breathing patterns.
Swimming may feel easier for someone who is already a confident swimmer.
In other words, the answer depends heavily on experience.
If you are a confident swimmer: swimming may be an excellent independent workout.
If you are nervous in the water or haven’t swum for years: water aerobics or shallow-water exercise may provide a gentler starting point.
Which Is Better for Joint Problems?
Both can be joint-friendly because water reduces impact.
Water-based exercise can be particularly useful for people who find certain land-based activities uncomfortable. The CDC notes that physical activity can help people with arthritis reduce joint pain and improve physical function, while swimming and water aerobics are examples of appropriate aerobic activities. (CDC)
However, individual responses differ.
A person with knee discomfort may prefer water aerobics because they can control the range and speed of movement. Another person may find swimming more comfortable because there is very little weight-bearing during laps.
If you have significant pain, recent surgery or a medical condition, discuss an appropriate exercise program with your healthcare professional before beginning.
Which Burns More Calories?
It is tempting to ask which workout burns more calories, but there is no universal winner.
Calories used during exercise depend on:
- Body size
- Exercise intensity
- Workout duration
- Swimming stroke
- Swimming efficiency
- Water temperature
- Fitness level
- Individual metabolism
A vigorous swimming session may require substantially more effort than a gentle water-aerobics class.
However, a challenging water-aerobics class may be more demanding than slow recreational swimming.
The best workout is therefore not necessarily the one with the highest theoretical calorie expenditure. It is the one you can perform safely and consistently.
Which Is Better for Building Strength?
Both activities can challenge muscles because water provides resistance.
Swimming repeatedly works the upper body, lower body and core as you move through the water.
Water aerobics can deliberately target particular muscle groups through movements such as leg lifts, squats, arm exercises and resistance exercises using water equipment.
For someone interested in general muscular endurance, either can be useful.
However, older adults should not assume that pool exercise completely replaces strength training. Current CDC recommendations for adults 65 and older include aerobic activity, muscle-strengthening activity and balance activities each week. (CDC)
A well-rounded routine may therefore combine pool exercise with appropriate strength and balance exercises.
Which Is Better for Balance and Confidence?
Water aerobics may have an advantage here.
Standing and moving in shallow water allows you to practice different movements while receiving support from the water. Mayo Clinic notes that water can provide support for people with balance difficulties while the movement of water can also challenge balance. (Mayo Clinic News Network)
For an older adult who is afraid of falling during exercise, this environment may feel more comfortable than exercising on a hard surface.
However, water is not risk-free. Slippery pool decks, incorrect entry into the water and swimming beyond your ability can all create hazards.
Always follow pool safety rules and use appropriate supervision when necessary.
What If You Don’t Know How to Swim?
You do not have to become a lap swimmer to benefit from pool exercise.
Water walking, shallow-water aerobics and other aquatic exercises can be performed without swimming laps. Mayo Clinic specifically notes that many aquatic exercises can be performed in shallow water without knowing how to swim. (Mayo Clinic)
However, basic water safety is still important.
If you cannot swim, choose a supervised pool environment and stay in an appropriate depth. Never assume that being able to stand in a pool means you are safe in deeper water.

So, Which Pool Workout Is Right for You?
Choose swimming if you:
- Already know how to swim confidently
- Enjoy exercising independently
- Want a structured full-body workout
- Like measuring progress through distance or laps
- Are comfortable controlling your own workout intensity
Choose water aerobics if you:
- Are new to pool exercise
- Have not swum for many years
- Prefer instructor guidance
- Want more variety
- Enjoy exercising with other people
- Feel more comfortable standing in shallow water
- Want to combine aerobic, mobility and resistance movements
And remember: you do not necessarily have to choose only one.
You could swim twice a week and attend one water-aerobics class. Alternatively, you could begin with water walking or aerobics and gradually introduce swimming as your confidence improves.
How Often Should Older Adults Exercise in the Pool?
The right schedule depends on your current fitness level and health.
For adults 65 and older, the CDC recommends at least 150 minutes of moderate-intensity aerobic activity per week, along with muscle-strengthening activities at least two days per week and balance activities. These recommendations can be adapted according to individual abilities and health conditions. (CDC)
You do not have to reach that amount immediately.
If you have been inactive, start with shorter sessions and gradually increase the duration and intensity.
For example, a beginner might start with 15–20 minutes in the pool two or three times per week and gradually work toward longer sessions.
Consistency is more important than trying to do too much during your first few workouts.
Making Pool Exercise a Long-Term Habit
The best exercise program is one you enjoy enough to continue.
If swimming laps feels repetitive, try water aerobics.
If group classes are not appealing, swimming may suit you better.
If both sound challenging, begin with water walking.
You can also explore different pool environments. Some community centers, fitness facilities, senior centers and wellness organizations offer aquatic programs specifically designed for older adults.

Frequently Asked Questions
Is swimming better than water aerobics for older adults?
Not necessarily. Swimming may be better for confident swimmers who prefer independent, full-body exercise. Water aerobics may be better for beginners, people who prefer classes and individuals who want a wider variety of movements.
Is water aerobics good for seniors with arthritis?
Water exercise can be a joint-friendly form of physical activity, and the CDC recognizes water-based exercise as an option for people with arthritis. However, the appropriate intensity depends on the individual’s condition and abilities. (CDC)
Can I do water aerobics if I cannot swim?
Yes. Many water-aerobics exercises take place in shallow water where participants can stand. However, basic water safety remains important, and you should choose an appropriate class and pool depth.
How long should an older adult swim?
There is no single ideal duration. Beginners may start with short sessions and gradually increase their workout time. A person’s fitness, health, swimming ability and recovery should determine the pace of progression.
Is swimming good for people over 65?
Swimming can be an effective aerobic activity for older adults, particularly for people who enjoy swimming and can do so safely. It can contribute to cardiovascular fitness, muscular endurance and overall physical activity.
Can water aerobics replace walking?
Water aerobics can provide aerobic exercise, but there is no need to view it as an either-or choice. Combining different forms of activity can provide variety and help address different fitness goals.
Should I choose a heated pool?
Water temperature can affect comfort and exercise tolerance. People with joint pain may prefer warmer water, while some higher-intensity activities may be more comfortable in cooler water. Ask the facility about its pool temperature and choose an environment appropriate for your needs.
Final Thoughts
Swimming and water aerobics can both be excellent choices for older adults.
Swimming offers a more skill-based, full-body workout that can be performed independently. Water aerobics provides greater variety, instructor guidance and an accessible way to exercise without necessarily knowing how to swim.
If you are unsure where to begin, start with the option that feels safest and most enjoyable.
The goal is not to become the fastest swimmer in the pool or complete the hardest water-aerobics class. The goal is to keep moving, build confidence and develop a sustainable exercise routine.
For many older adults, the best pool workout is simply the one they enjoy enough to keep doing.
