Why Athletes Switch
Everything the HW9 gives you, session after session.
Precise intensity control
Know whether you are training easy, moderate or hard instead of relying on perceived effort alone.
Zone-based training

Track your progression
Compare heart rate, pace and output week after week to see real fitness gains.
Built for intervals
Ideal for running, cycling and gym work where effort and recovery both matter.
Kinder than a chest strap
Sits on the upper arm — no tight band squeezing your ribcage, no chafing.
Bluetooth & ANT+
Streams live to watches, phones, bike computers and gym equipment simultaneously.
Ready in seconds
Slide it on and go. No wetting electrodes, no fiddling before a session.
Spot unusual strain
If your heart rate is unusually high for an easy pace, that's your cue to back off.
Say Goodbye
to Chest Straps
Superior comfort
No restrictive chest compression or chafing. The soft-touch elastic band sits perfectly on your upper arm.
Optical precision
Dual-mode Bluetooth and ANT+ for lag-free data to your watch, phone or gym machine.
Sweatproof & durable
IP67 rated. From drenched turbo sessions to muddy trail runs, the HW9 never misses a beat.
