Vi Trainer’s adaptive audio coaching provides users with real-time guidance and motivation during their workout routine. Its personalized approach ensures that users get the most out of their training sessions by offering a variety of exercises. Vi Trainer optimizes sets, reps, and weights for each exercise, ensuring tailored and effective workouts. The importance of a personalized workout plan generated by Vi Trainer cannot be overstated.
Vi Trainer is a conversational fitness coach, initially available for running. It uses various signals from your phone (GPS, movement of phone etc) to detect how you’re doing. Its sassy coach motivates you to push yourself safely. I personally definitely exercised more on my first go than I’d have done before.
How does Vi Trainer Work?
Vi Trainer is an app, which means you’ll need a smartphone to be able to start using it as well as some headphones (Vi talks to you whilst you run).
Once Vi Trainer is installed, Vi will ask some questions about you including things like your current fitness level, gender, age, and what your main goal is, run faster, further, etc.
When you start using the app, Vi will then begin coaching you towards your goals in real-time. Based on your performance and goals, she creates dynamic and fun workout experiences tailored to you. These workouts can be either be done outdoors or indoors on the treadmill.
Vi Sense Wireless Headphones FAQ
How do I connect my Vi Sense Headphones to my phone?
Turn your Vi Sense Headphones on, you should hear Vi say “Searching for Devices”. Open your phone’s Bluetooth settings and click on “Vi Earphones” to connect them. Once it says connected in your Bluetooth settings, you’re all set!
How long does it take to charge Vi?
It takes roughly 90 minutes for Vi to reach a full charge! When you plug Vi into your micro USB charger, the Vi logo on your neckband will flash green until it’s fully charged. When fully charged this logo will change to a solid green light.
How long does the battery last?
Vi’s average battery life is 8 hours. This number varies depending on how you are using Vi (i.e. training with Vi, listening to music, making phone calls, etc.).
You can check Vi’s battery level, at any time, by pressing both the plus (+) and minus (-) buttons on Vi’s neckband.
What do the buttons on the side do?

A short press will increase the volume.

Minus (-) Button

A long press on the middle button will turn the device on/off.
How does the heart rate sensor work?
Vi measures heart rate using an optical heart rate sensor in the left earbud. The sensor emits a green light in a specific wavelength to the tissue of the tragus in the ear. The reflective light is captured by the receiver of the sensor — this is then processed by a proprietary algorithm to capture the heart rate.

What are the Benefits of Using a Virtual Running Coach?
Motivation
It’s hard to do anything consistently without a little motivation giving you a nudge. Vi Trainer provides motivation through its many workouts from ‘speedplay’ to ‘long runs’, and ‘intervals’ to ‘tempo runs’.
It’s great that you can choose any one of these workouts by how long it is expected to take, simply by applying a duration filter, as you may only have 30 mins available for your run. you can further filter those results to find a workout based distance or difficulty level.
Accountability
Showing up for a run is half the battle. Having a trainer of any kind, physical or virtual holds a certain degree of accountability. If you don’t show up, you’re in trouble! Ok, so Vi won’t actually punish you but you’ll want to keep showing up just to hear the nuggets of advice she provides on your next run. Vi also rewards you for your efforts by giving you a shout out to the whole community if you do amazing things, like show up really regularly. It’s so cool when Vi mentions someone from a completely different country and shares their hard work with you. In fact, it motivates you to want to do the same.
Virtual Races are Included!
If you’re subscribed to Vi Trainer then you get to run the Virtual 5K races for free! Every so often Vi puts on these events where you have the opportunity to compete with other Vi uses from around the world. I love how Vi pushes you during the race and gives you real-time updates on how well you’re doing compared to the other participants, and even how well you’re doing within your country or state. Running a virtual race something that needs to be experienced at least once in your life!
