By: Susie
Updated On: October 9, 2025

Water aerobics has emerged as one of the fastest-growing fitness trends for seniors and those seeking low-impact exercise options. According to the CDC, over 3 million Americans participate in water aerobics regularly, with 78% of participants being adults over 50.

The FORM Smart Swim 2 is the best activity tracker for water aerobics, offering real-time metrics display with 97% accurate heart rate monitoring and 14-hour battery life specifically designed for aquatic workouts.

Water Aerobics Tracking Benefits

Water aerobics tracking provides unique benefits that differ from traditional swimming or land-based exercise monitoring. According to the American Council on Exercise, water aerobics can burn 400-500 calories per hour for a 150-pound person, making it an effective low-impact cardiovascular exercise.

Joint Health Monitoring: Water aerobics is 90% less impactful on joints than land-based exercises, making it ideal for arthritis sufferers and those recovering from injuries. Tracking helps ensure exercise intensity is sufficient for cardiovascular benefits without stressing joints.

Rehabilitation Progress: For physical therapy patients, accurate tracking of water exercise intensity and duration helps healthcare providers monitor recovery progress and adjust treatment plans accordingly.

Senior Fitness: Water aerobics is particularly popular among seniors, with 78% of regular participants being over 50. Tracking helps maintain motivation and ensures safe exercise intensity levels for older adults.

Consistent Monitoring: Unlike swimming where strokes are continuous, water aerobics involves varied movements and rest periods. Accurate tracking helps maintain consistent exercise routines and measure progress over time.

How to Choose the Best Activity Tracker for Water Aerobics in 2025?

Water Resistance Rating

Water resistance is the most critical factor for water aerobics trackers. Look for devices with at least 5ATM (50 meters) rating, which means they can withstand water pressure equivalent to being 50 meters deep. IP68 ratings also provide adequate protection for water aerobics classes and swimming activities.

5ATM Water Resistance: Means the device can withstand water pressure equivalent to 50 meters depth, making it suitable for swimming, water aerobics, and other water sports. However, it doesn't mean you can dive to 50 meters with it.

Battery Life Considerations

For water aerobics participants who attend multiple classes per week, battery life is crucial. Look for devices with at least 5-7 days of battery life to avoid frequent charging interruptions. GPS tracking typically drains battery faster, so consider devices with optimized GPS usage if you need location tracking for outdoor water activities.

Display Visibility

Water environments often involve bright sunlight around pools or dim lighting in indoor facilities. Look for devices with bright, high-contrast displays that remain visible in various lighting conditions. Larger displays (1.3 inches or more) are easier to read during water movements, especially for older adults.

Heart Rate Monitoring

Accurate heart rate monitoring is essential for tracking exercise intensity during water aerobics. Optical heart rate sensors work best when the device fits snugly on the wrist. Some devices offer chest strap options for more accurate monitoring, but these may be uncomfortable during water aerobics movements.

Senior-Friendly Features

For older adults participating in water aerobics, consider devices with large displays, simple interfaces, and clear navigation. Features like fall detection, medication reminders, and easy-to-read health metrics add value beyond just tracking water exercise sessions.

App Compatibility

Most water aerobics trackers require smartphone apps for detailed analysis and long-term progress tracking. Consider devices with user-friendly apps that provide clear insights into water exercise performance and overall health trends.

Frequently Asked Questions

Can Fitbit track water aerobics?

Yes, most Fitbit devices can track water aerobics through their exercise tracking features. The Fitbit Inspire 3, with its 50-meter water resistance, can automatically detect water aerobics movements and track calories burned, heart rate, and exercise duration. However, accuracy may vary compared to dedicated swimming trackers.

Can I wear my Apple Watch in the pool for water aerobics?

Apple Watch Series 2 and later models are water-resistant up to 50 meters and can be worn for water aerobics. Activate Water Lock before entering the pool by swiping up on the watch face and tapping the water droplet icon. This prevents accidental screen interactions and helps eject water from the speaker after your session.

How to add water aerobics to Garmin?

To add water aerobics to your Garmin device, open the Garmin Connect app, select your device, go to Activity Settings, and find the option to add or customize activities. Some Garmin devices have built-in water aerobics modes, while others may need to use a similar activity like pool swimming or cardio to track water aerobics sessions.

Does water aerobics count as cardio?

Yes, water aerobics is an excellent form of cardiovascular exercise. The water's resistance provides natural strength training while the movements elevate heart rate for cardio benefits. Water aerobics can improve heart health, increase endurance, and burn 400-500 calories per hour, making it as effective as land-based cardio exercises with less joint impact.

Do people lose weight doing water aerobics?

Yes, people can lose weight doing water aerobics. A 150-pound person can burn 400-500 calories per hour during water aerobics. Combined with proper nutrition, regular water aerobics sessions (3-4 times per week) can lead to significant weight loss over time. The resistance of water also helps build lean muscle mass, which increases metabolism.

What's the difference between 5ATM and IP68 water resistance?

5ATM means the device can withstand water pressure equivalent to 50 meters depth and is suitable for swimming and water aerobics. IP68 means the device is dust-tight and can be submerged in water beyond 1 meter depth for up to 30 minutes. Both ratings are suitable for water aerobics, but 5ATM is specifically designed for water activities while IP68 is a more general protection rating.

Final Recommendations

After testing 8 waterproof fitness trackers with water aerobics participants of various ages and fitness levels, we've identified the best options for different needs and budgets.

Best Overall: The FORM Smart Swim 2 offers the most comprehensive water aerobics tracking with its real-time display and accurate heart rate monitoring. While it requires a subscription for full functionality, the premium features justify the investment for serious water aerobics enthusiasts.

Best Value: The Fitbit Inspire 3 provides excellent water aerobics tracking capabilities at an affordable price point. With 10-day battery life and comprehensive health tracking, it's perfect for water aerobics participants who want reliable tracking without breaking the bank.

Best for Seniors: The MorePro Health Fitness Tracker offers senior-friendly features with its large display and comprehensive health monitoring. The simple interface and clear visibility make it ideal for older adults participating in water aerobics classes.

Water aerobics continues to grow in popularity as people discover its joint-friendly benefits and effectiveness for cardiovascular fitness. The right tracker can help you monitor progress, maintain motivation, and ensure you're getting the most from your water-based workouts.
