Mio, which was one of the first companies to make a watch that could accurately measure your heart rate without an additional chest strap, has decided to downsize. They've taken the brains of the Mio Alpha, then they shrunk it and got rid of its face. What we've got left is a pulse reading wristband called the Mio…
Chest-strap heart rate monitors suck. I mean, yeah, they work okay, but they give you that tight-chest-"am-I-having-a-heart-attack?" feeling. That's why the Mio Alpha, a wristwatch that accurately measures your heart rate, is such a big deal. But that doesn't mean it's perfect.
There are a million reasons to want to know your heart rate while working out. Maybe you're trying to stay in a certain range for fat-loss. Maybe you want metrics on how you're progressing. Maybe you just need to make sure your heart isn't about to explode.
