Taking the guesswork out of fitness

Our Mission
We believe everyone deserves access to amazing training. Our mission is to make world-class, research-based workouts accessible to everyone, everywhere.
Countries we're in

Total squats performed

3 Billion

Volt users train hard—and with every workout completed, we’re gaining valuable data insights that help us take the sport and fitness industries to new heights.

Year Cortex launched


The year we introduced Cortex, the world’s first performance training AI, to adapt and personalize workouts to each user in real time, optimizing both safety and results.

It all starts with the plan

Exercise science research shows that workouts are more effective when part of a long-term, structured plan. Volt creates personalized training plans that  adapt to each user’s feedback—so they get the right workout, every time.

Helping people reach their goals

Whether it’s training for a sport, job, or general health and fitness, Volt shows users exactly what to do to reach their goals.
On the field

Athletes and coaches trust Volt for quality, affordable training guidance that helps prevent injuries and take their teams to the next level.

In the field

Military personnel, law enforcement, and first responders use Volt to help them achieve tactical readiness—and stay healthy—no matter the job.

At the gym

From experienced workout warriors to people just starting their fitness journey, Volt provides expert guidance to help them achieve their goals step by step.

For the 9-5

From warehouse workers to desk jockeys, Volt makes workplace fitness easy to adopt (and scale) for companies large and small.

For the finish line

Volt helps triathletes, marathoners, cyclists, and other endurance athletes peak for race day, ski season, or whatever keeps them moving.

What we’re about

Incredible training, delivered through beautifully designed technology—that’s Volt.

Backed by science

Volt’s training content is based on 50+ years of exercise science research. Workouts are never randomly generated, but intentionally built to progressively guide people toward their fitness goals at their own pace.

AI that moves the needle

Cortex, Volt’s training AI, analyzes each user’s progress and predicts what they’ll need next with data-driven precision. Like an expert trainer, Cortex understands how a user is responding to their workout and updates their training in real time.

User-centered design

Volt workouts are delivered through an intuitive and beautiful fitness app. Thoughtful and responsive design combine to make every workout easy to follow—so users can focus on the training, not the technology.
