05 / A note from the founders

“We're making lifting a science, not an art.”

Ten years of lifting taught us how easy it is to train hard and go nowhere.

We're building Theorem to take the guesswork out of strength training, and help you make more of every minute in the gym.

06 / A few good questions

Before you join.

Are the coaches real people?

No. They're AI coaches with different training focuses and ways of communicating.

Do I need my phone to train?

Only to tap in, if you choose. A wearable or Theorem band works too. The station handles your workout.

What if the gym doesn't open?

If 100 founding members don't join by 30 November 2026, every payment is automatically refunded.

Can I cancel my membership?

Yes. Month to month, after the initial six months if you chose to prepay. Your deposit is refundable before opening.

Something else on your mind?

Theorem

How it works

You lift – Theorem tracks and coaches

Every rack, bench and machine has cameras and sensors. Theorem counts your reps, reads the weight, and coaches your form.

Coaches

Pick from our library of coaches – or use your own.

A few examples from the library, each an expert in a different kind of training with its own way of coaching, and all reading the same measurements from your set. Or build your own, or send your data to the AI agent you already use.

Membership

Founding members pay less, for life.

Hold a founding spot with a $99 deposit, taken off your first month, and keep your founding rate for as long as you stay. The earlier you join, the lower it is. Or prepay your first six months for $499 and get the welcome package now. Theorem opens once 100 founding members join; if it doesn't, every payment is refunded.

The founders

We're making lifting a science, not an art.

Kulan & Kevin, founders of Theorem

Why we're building Theorem

Hey! It's Kulan and Kevin, the founders of Theorem.

Ten years of lifting taught us how easy it is to train hard and go nowhere. Personal trainers fixed that for an hour a week, and then we were back to being on our own.

We built Theorem to take the guesswork out of strength training, and help you be as effective as possible with each minute you spend in the gym. We're making lifting a science, not an art.

If you're interested in learning more, or have ideas on how to make Theorem better, we'd love to hear from you.

FAQ

Questions, answered.

Anything else, book a call with the founders and ask.

Every rack, bench and machine has its own cameras and screen. Theorem counts your reps, reads the weight, checks your form and logs every set, so you get a coach's eye on every lift without booking a trainer.

It holds your founding spot and your founding rate, and comes off your first month. You can get it back any time before opening.

Your first six months for $499, less than six months at any founding rate, and the welcome package as soon as you pay: your metal key card, a Theorem founding hoodie in your fit and size, and a few surprises. Your six months start the day Theorem opens.

No. Tap in at a station with your phone, a wearable or your Theorem wristband. After that you just lift; the station does the logging.
