How it works

TRAINER ASSIGNMENT

First, we’ll pair you with an elite trainer. All of our trainers have an M.S. and 15+ years of experience.

TAILORED WORKOUTS

LIVE FEEDBACK

The difficulty and form of every rep you do is measured automatically. No manual input needed.

Your trainer is in the loop

Your trainer can see and analyze your every rep with our motion analysis technology. From just the movement of your wrist, we detect sets, count reps, estimate difficulty, and grade form.

Trainer Note

We were stuck

Fitness YouTube videos and friends could only get us so far. We needed programming and accountability from a real trainer, but price and our busy schedules kept us away. As athletes and engineers from MIT and Carnegie Mellon, we set out to fix personal training.

AI + Human Trainers

First we built a completely automated workout app, but quickly learned that human trainers cannot be replaced by chatbots and neural networks. That’s why we stopped trying to replace trainers and instead made them superheroes. 

What Our Clients Are Saying

“It’s great to have a personal trainer to chat with during the workout and beforehand to plan. To not have to think about planning my own workouts reduces the stress associated with gym time for me.”
