Fitness tracking and wearables are a huge market, and you might even have a device on your holiday wish-list. Pretty likely when I mentioned resting HR, you thought about checking yours on the device on your wrist.
I’m a data junkie: most of my training is heart-rate based, and I have a Garmin Forerunner 35 plus a Garmin Index Smart Scale. But a lot of that data is logged, recorded, archived … and never used for anything.
So what the heck do all these numbers mean, and which ones matter? I talked to two guys named Matt who helped me sort through the data I’m collecting to help make me and YOU better runners.
