Why did you join a gym?

You want to lose fat and build muscle.
But there's far too much to figure out.

“What am I even supposed to train today? And how much weight, for how many sets?”

“So many grams of protein, so many calories. I'm supposed to do that math every day? I'd last three days.”

“How many hours of sleep, how much water, is my form right. It never ends.”

Those calls? We'll make them all for you.
Decided one by one, around your body and your situation.

FAQ

Frequently asked questions

Is it OK if I've never had a personal trainer?

It's designed for complete beginners. During onboarding we learn your current training background, eating habits and goals, then suggest a routine and a meal plan you can follow from day one.

How does billing work?

It's an auto-renewing subscription at $4.99 per month. It renews automatically every month and continues until you cancel. Payment goes through the App Store and Google Play only, and if you cancel before your next billing date you won't be charged again.

How do I cancel?

You can cancel anytime from subscription management in the App Store or Google Play. Inside the app, My > Manage subscription also shows your status and points you to the cancellation flow. There are no penalties or cancellation fees.

Do I lose my records if I cancel?

No. Even after you cancel, your workout, meal and weight records are kept as they are, and you can pick up where you left off if you subscribe again.
