An AI-powered personal trainer might seem like something from a 1950s sci-fi comic, but Vi is the real deal. She is the latest creation from NYC-based LifeBEAM, lives in a pair of biosensing headphones, and is ready to help you achieve your fitness goals.

Running with Vi is like working out with a super-motivating friend: She gives tips along the way and pushes you when you need it. And since Vi measures your heart rate and pace—and is constantly learning more about your habits, energy levels, challenges, and limitations—she’s able to create an ever-evolving, totally personalized training plan.

Vi also has a high-quality Harman Kardon audio system, so you can listen to whatever music and podcasts you want. When training, she'll match songs to your pace to fit even more seamlessly into your workouts!

For the price of a couple PT sessions at your local gym, Vi is a true investment in your fit and healthy future!

Right now, LifeBEAM is offering Greatist readers a $50 discount on Vi. And since the company knows you’ll immediately be sold on her, it’s also offering $50 cash for every friend you refer!
