Product Description
Hard training is only part of the picture, but how well you recover from it, and show up tomorrow, matters just as much. A band with no screen, no notifications, and a battery that lasts up to 8 days records those key metrics without any distractions.
The Polar Loop reads your heart rate with an optical sensor that shines light into your skin and measures blood flow. Heart rate variability, the small differences in timing between heartbeats, goes into Nightly Recharge along with your sleep score and breathing data to rate your overnight recovery. Training Load Pro then compares the strain of each session with what your body can currently tolerate, so you can see recovery and training side by side in the Polar Flow app.
