Trainer Rex now
Leg day done! Here is your summary: Squat 100kg x 5 — that is a 5kg PR since last month.
I am bumping your working sets to 102.5kg and adding split squats for balance.
Nice, what about tomorrow?
Upper push is ready. I adjusted shoulder press based on last week. Have a good one!

Sound familiar?

PTs cost a fortune

$300–600/mo just for someone to count your reps. Good coaching should not be a luxury.

Apps don’t coach

Generic plans that ignore your injuries, your plateaus, and your missed sessions.

Motivation fades

Without accountability you start strong, then quietly give up by week four.

Is Trainer Rex right for you?

Rex is for you if:

  • ✓You want coaching without the PT price tag
  • ✓Generic apps have not worked for you
  • ✓You need someone keeping you on track
  • ✓You want a plan that grows with you

Maybe not for you if:

  • •You need someone to fix your form in person — Rex cannot spot you, his arms are too short
  • •You only want nutrition coaching (coming later)
  • •You want a human coach — Rex is AI and finds that comparison offensive

Built to make you stronger

Why I built Trainer Rex

R

I train 4–5 times a week but kept hitting plateaus. The quarterly gym check-in did nothing. A real PT? Hundreds a month, for someone who already knows how to squat.

So I built an AI trainer that does what a great PT would: watches your numbers, adapts your plan, keeps you honest. At a price that makes sense.

— Raphael, founder

Questions? Rex has answers.

The coaching chat runs on Telegram for now (free, 30 seconds to set up). More channels coming. The tracker works in any browser.

Tell Rex once. Every plan after that takes it into account.

Yes. No contract, no fees. Data stays if you come back.

Stop overpaying for coaching.
