Launch offer Get Rex for $17.99/mo $29.99
The workout tracker that actually coaches you.
Personalized plans, progress tracking, and a coach that adapts your training after every session. A month of Trainer Rex costs less than 10 minutes with your personal trainer.
Sound familiar?
Good coaching is expensive
A great personal trainer does a lot, but at $100–150/hour most people can only afford a session a week, if that.
Tracking apps just record
Rep-logging apps store your sets and charts, but they never tell you what to do next or change the plan when life gets in the way.
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
- You train at home, at the gym, or with whatever equipment you have
- You are new to lifting or getting back after time off
Maybe not for you if
- You need someone to fix your form in person. Rex cannot spot you, his arms are too short
- You mainly want nutrition tracking. Rex can give food advice, but he does not track meals or calories.
- You want a coach in the room with you. Rex handles your programming and accountability through your phone, not in person.

Every rep, every weight, every note. Rex knows about your shoulder and that you prefer dumbbells. No repeating yourself.
Smart progression
Hit your reps? Rex adds weight. Missed a set? Plan adapts. Steady progress, tuned to you.

Why I built Trainer Rex
I train 3–4 times a week but kept hitting plateaus. My tracking app had all the data and none of the answers. I wanted real coaching, but at $100–150/hour I could not justify it every week.
So I built an AI trainer that does what a great PT would: watches your numbers, adapts your plan, keeps you on track. At a price that makes sense.
Questions? Rex has answers.
Those apps log your workouts. Rex writes the plan, adjusts it after every session, and keeps you accountable.
No. Tell Rex your goals and equipment then he builds the whole plan for you.
Yes. Rex builds around whatever you have, from a full gym to a pair of dumbbells.
Through Telegram or email. Log a session, ask a question and Rex replies and updates your plan.
You get full access for 7 days. After that, subscribe for $17.99/mo to keep using Trainer Rex. There is no free plan after the trial.
Yes, month to month, no fees. Your history is waiting if you come back.
Stop overpaying for coaching.
7 days free. No credit card. If Rex does not earn his spot, walk away.
Setup takes about 2 minutes.
