I've been using, Vi, the headphones that are also a personal trainer, and I'll never go back to running alone

When it comes to fitness gadgets the general rule is that the current generation tend to overpromise and under deliver.

But in the case of the artificial intelligence headphones called Vi, designed to improve your running, I've been blown away by how much more it does than I imagined.

Not that I haven't had some issues with them, but the way they've helped correct and improve my running form far outweighs the annoyances. I can run longer and faster with less knee pain and soreness.

Vi gained attention in 2016 when it raised nearly $1.7 million on Kickstarter on a goal of $100,000.

I tried Vi for a wide variety of workouts before I came to the conclusion that I love this device.
