Vi Trainer delivers on-demand cardio audio workouts that are fun, effective, and adapt to you in real-time while you work out. Vi also understands you and your goals and creates the optimal path for YOU to achieve them. Say goodbye to stale pre-recorded workout classes and enjoy the future of digital fitness, right in your ear.

In featuring Vi Trainer, The Wall Street Journal proclaimed that “The Future of Fitness is In Your Ear”. We couldn’t agree more.

REAL-TIME GUIDANCE: Vi’s human voice coaches you in real-time based on your biometrics, making for a more dynamic and effective workout.

HAVE FUN WHILE WORKING OUT: Vi makes working out fun, engaging, and fluid. No more static audio workouts.

FASTER RESULTS: Vi understands your goals and creates a personalized plan to get you there. And she adapts as you go, always guiding you on the most efficient path to your goals.

CONVENIENT: Vi is always right in your ears, whenever and wherever you are. No more excuses.

PERSONALIZATION: Vi uses many data-points to know you better than a human personal trainer. Your workouts become more fun, effective, and personalized because of that.

User Reviews:
“I was feeling bored of running alone. Vi has become a part of my routine and more like a friend who encourages me to keep going on. I am in love with Vi.”

“I have always wanted to try out a personal trainer but couldn’t afford to. Vi has been just that without the regular fee! I have also gone down from a size 14 to a size 10!”

“When I was first starting to run, I had no idea what I was doing. Vi has taught me all of the essentials like rhythmic breathing, keeping a steady pace, and taking shorter strides.”

“Her sense of humor is great. I actually burst out laughing while running on the road when she said something funny.”

“With the help of Vi I now run 3-4 times per week and track my walking as well. I have lost 12 lbs. and am only 3 lbs. away from my current weight loss goal. I lost a full pants size.”

“Probably the thing I have found most useful is the stepping-to- the-beat. This is a huge improvement and something I always tried to improve on in the past but never made it stick. Vi has gone above and beyond sorting that out!”

“I’ve lost 50lbs. I have tried multiple apps but having Vi run with me and be so knowledgeable about me as a runner has been second to none.”

Doesn’t match up

I did what was supposed to be an intermediate run with 45 second sprints. The problem is those “sprints” were only 5.6 on the treadmill. No problem, I’ll just start over and kick my experience level up to advanced. When it gave me a new plan there were still no level 3 runs. At one point I did a workout that said it was going to be 3 miles in 30 minutes but the whole time it told me to run at a 4.7 pace. How does the math work out on that? If I stick this plan out I’ll actually be reversing the conditioning I’ve done on my own over the past few weeks and I’m no pro either. Oh, and the app doesn’t let you incorporate the heart rate monitoring native to the Apple Watch. If you want to do that they want you to purchase their proprietary heart rate monitoring headphones. No thanks! In fact, it does not even have an iwatch app. The best thing I can say about the app is the coaching is the best I’ve seen in an app. Having her say my name from time to time was a nice touch. I really want to like this app but I’m still deleting it.

I was looking for something to help get me back into shape after having a baby and I needed something I could do on my own time rather than trying to make it to gym classes. A friend recommended I try Vi and I’m so glad I did! The quality and variety of workouts are really impressive and after just a few weeks of using Vi I feel like I’m already a better runner than I ever was before. Interval training, speed, distance, etc - Vi has it all and at every level. I can’t recommend this product enough for anyone looking to improve their fitness/running chops. I look forward to continue to run with Vi and see what additional features continue to roll out.

Who beta tests this?

If you have a beta test program I’d love to sign up and help.
“Short and sweet” is not short enough. Sometimes I listen to podcasts and audiobooks while I run andI don’t need Vi in my ear every 30 seconds to a minute to give me motivation or hear her impression of a bird. All I need are the stats I’ve set up at the intervals I’ve set. I fear what her chattier settings are like.
In the pre made runs we need a setting to change the speed to a pace. Im used to dealing with pace not speed. It’s easier for a runner to know what a pace of 10:00 feels like over a speed of 6 miles an hour. And it gets harder trying to do the math in my head for a speed of 6.5 miles per hour.
