Swimming is an excellent full-body workout, but monitoring your heart rate in the water can be challenging. Unlike running or cycling, traditional heart rate monitors may not work effectively underwater.
However, with advancements in wearable technology, live heart rate monitoring while swimming is now possible.
In this guide, we’ll explore the best methods, devices, and apps—including BodyWave, a powerful tool for tracking body activity and analyzing performance data—to help you optimize your swim sessions with real-time heart rate insights.
Why Monitor Your Heart Rate While Swimming?
Optimize Training Intensity
Tracking your heart rate helps ensure you’re training in the right zone—whether it’s fat-burning, endurance, or high-intensity intervals.
Prevent Overtraining
Consistently high heart rates may indicate overexertion, increasing injury risk. Monitoring helps you adjust intensity as needed.
Measure Progress
Heart rate data provides objective metrics to track improvements in cardiovascular fitness over time.
Best Devices for Live Heart Rate Monitoring in Water
Chest Strap Monitors (with Waterproof Features)
Some chest straps, like the Polar H10 or Garmin HRM-Swim, are designed for swimmers, transmitting heart rate data to compatible watches.
Pros:
- High accuracy
- Syncs with smartwatches
Cons:
- Can feel restrictive
Optical Heart Rate Watches
Devices like the Garmin Swim 2 or Apple Watch Ultra use optical sensors to measure heart rate underwater.
Pros:
- No chest strap needed
- Tracks additional metrics (lap count, stroke type)
Cons:
- Slightly less accurate than chest straps
Ear Clip Monitors
Less common but useful for swimmers who prefer minimal gear.
How to Use BodyWave for Activity Tracking & Data Analysis
If you’re looking for a smart way to monitor your body’s performance beyond just heart rate, BodyWave is a great solution. This app syncs with compatible wearables to provide:
- Real-time heart rate tracking
- Swim stroke analysis
- Calorie expenditure estimates
- Post-workout recovery insights
With BodyWave, you can review trends over time, adjust your training plan, and even compare swim sessions for better progress tracking.
Tips for Accurate Heart Rate Monitoring While Swimming
Ensure Proper Device Fit
A loose watch or chest strap can lead to inaccurate readings.
Wet the Sensors Before Swimming
For optical sensors, a little water helps improve contact with the skin.
Use a Dedicated Swim Mode
Many smartwatches have a "swim mode" that optimizes heart rate tracking in water.
Check for Interference
Avoid crowded lanes where accidental bumps might displace your tracker.
Conclusion
Live heart rate monitoring while swimming is no longer a futuristic concept—it’s accessible with the right gear and apps like BodyWave. By tracking your heart rate, you can train smarter, avoid burnout, and achieve better results in the pool.
