The best chest strap heart rate monitors, according to Amazon reviews
No more slipping, sliding or shimmying with these chest straps.
Polar's H10 chest strap heart rate monitor is a refinement of the popular H7, which many runners heralded as the gold standard for heart rate monitors when it came out in 2013. The H10 features a 400-hour battery life, comfortable strap at a medium width and built-in memory for one training session. "Best heart rate monitor I have ever seen! Physical therapist and doctor recommended."
The Polar T31 is not so much a heart rate monitor in and of itself -- meaning, it doesn't do all the fancy things that other devices on this list do. The T31 is actually a transmitter that works by capturing your heart rate with a waterproof ECG and sending it to your fitness watch. It can also connect to treadmills for indoor runs. : Reviewers praise this heart rate transmitter for its accuracy and ease of use, plus its ability to connect to multiple third-party machines and devices.
Shanren Beat 20
Can't stand carrying your smartphone on your run? Fret not, as the Shanren Beat 20 stores data for up to 100 training sessions, which you can later transfer to your phone via the Shanren Sport app. This strap also offers a unique vibration alert feature that warns you when you're approaching the max heart rate you set in your app.: "It is extremely user-friendly, easy to read and understand, lightweight."
Wahoo Tickr X
Another phone-free chest strap, the Wahoo Tickr X connects to just about anything, including phones and tablets, Garmin watches and more than 50 fitness apps. This monitor features a wider, soft strap that adjusts from 23 inches to 48 inches. Reviewers praise this unit for its accuracy and ease of use, but do warn that it could be more durable. Related:
A super thin chest strap with an impressive year-long battery life (if you run for one hour, once a day), the Garmin HRM-run features a small, lightweight monitor that captures six cool running metrics: cadence, vertical oscillation ("bounce" in your run), ground contact time, left/right balance, stride length and vertical ratio (oscillation height to stride length).: "Best HRM chest strap! The fit is comfortable. It performs flawlessly and never loses connection."
If you sprinkle in other forms of training -- specifically, biking and swimming -- you should check out the Garmin HRM-Tri, which captures all the data that triathletes need to know and reports it all back to any compatible devices you sync it to. "Easily the best chest strap heart rate monitor that Garmin has made" and, quite simply, "Best thing ever!"
If you're looking for a budget buy, this is it. The CooSpo IP67 chest strap uses ANT+ technology and Bluetooth, which allows it to sync and work wirelessly with probably any device you already have. Coming in at just $30, buyers love the value for the price. "Great alternative to name brand units for less money," and "Great price and will easily pair with all popular devices and products. Strap feels comfortable and transmission is very accurate."
