Garmin HRM 600 chest heart rate monitor with M-XL strap, rechargeable module and advanced running metrics

Designed for athletes who rely on data, the HRM 600 pairs wirelessly with Garmin smartwatches, cycling computers, gym equipment, and third-party apps to transmit live metrics or store workouts when a watch isn’t practical. The unit combines a rechargeable module with a comfortable, machine-washable strap available in sizes XS–S and M–XL. It records heart rate, calories, pace, distance, and advanced running metrics to help you analyze performance across running, cycling, swimming, and team sports.

How does the HRM 600 deliver more accurate heart rate and HRV data?

The HRM 600 uses a chest-mounted sensor to capture electrical heart signals directly, which reduces noise and improves signal accuracy compared with wrist-based monitors. It transmits data in real time to compatible devices and also stores sessions on the module when you’re not wearing a watch.

• Chest strap placement for cleaner ECG-style signals
• Real-time ANT+ and Bluetooth connectivity to watches and cycling gear
• Onboard storage for recording sessions without a paired watch
• Accurate HRV metrics for recovery and training analysis

What running dynamics and gait insights can I get with a compatible smartwatch?

When paired with a compatible Garmin watch, the HRM 600 supplies advanced running metrics that reveal how your body moves and where efficiency can improve. It measures stride length, vertical oscillation, ground contact time balance, and a unique step speed loss metric to show deceleration at foot strike.

• Stride length for cadence and efficiency adjustments
• Vertical oscillation to track bounce and energy waste
• Ground contact time balance to identify left/right imbalances
• Step speed loss to quantify slowdown on impact

Can I use the HRM 600 when a watch isn’t practical, like in team sports or swimming?

Yes — the HRM 600 can record workouts independently of a watch and later sync full session details to the Garmin Connect app. It also captures accurate heart rate during swims and uploads the data after you end your activity, making it versatile across disciplines.

• Independent workout recording for team sports or contact play
• Swimming-compatible heart rate capture with post-swim sync
• Pace and distance support for indoor treadmill sessions sent to compatible watches
• Calories, speed, and distance stored and transferred to Garmin Connect

How long does the battery last and how easy is maintenance?

The HRM 600 uses a rechargeable battery that delivers up to about two months of typical use on a single charge, depending on training frequency. The module detaches from the strap so you can toss the textile strap in the laundry after hard sessions while keeping the electronics dry.

• Rechargeable module — up to two months between charges
• Removable electronics for safe washing of the strap
• Durable textile strap available in two sizes for a secure fit
• Simple pairing via Bluetooth and ANT+ to multiple devices

Who this is for: The Garmin HRM 600 suits serious runners, triathletes, cyclists, and team-sport athletes who want sensor-grade heart rate and detailed running dynamics. It’s ideal for data-driven training plans, coaches tracking athlete metrics, and anyone who needs reliable heart rate recording when wearing a wrist device isn’t feasible. Choose the M–XL strap for a secure, comfortable fit and pair it with compatible Garmin devices to get the most from your workouts and recovery tracking.
