I'm just wondering how much, if any benefit the band has in usage with a CrossFit style workout. Most of the reviews I've seen really only talk about running fitness with them.
I did a workout this morning and I can honestly say this thing tracked it just right. I love the data that it gives and cant wait to start seeing the Vo2 max and graphs after a few workouts.
The Health app estimates your VO2 max by analyzing the relationship between your heart rate and speed during activities tracked in tiles like the Run Tile or the Bike Tile. As you work harder, your heart rate, speed, and oxygen consumption increase. Recording more runs or bike rides, with increased effort, may improve the accuracy of your VO2 estimates.
