+ 23 more days already written, and it keeps going as you do
An AI coach writes your training plan and macros, shows every exercise on video, keeps your progress and writes recipes that fit. Say it, or send a photo.

Create plan based on situation
Why this week
Four lifting days, one run, one swim. That is what lean mass without losing the engine looks like on a calendar.
Why it changed
Squats out, hip thrust and sled in. Same volume, none of it through the knee. Tuesday runs as a swim until you tell me otherwise.
Why it changed
Three full-body sessions instead of five splits. Nothing that matters is lost, and the swim moves to next week.
Why it changed
Block shifts toward running on tired legs. More sled, more compromised running, the lifting days stay where they are.
Why it changed
Hotel room and street. Same stimulus without a barbell. We pick the loading back up the day you are home.

“I want to put on lean mass, I can train four days.”
That sentence is the entire input. The coach asks your age, weight and height once, then works from whatever you tell it, in as much detail as you have or as little.
What the coach wrote back
Real loads, carried forward from what you did last week, with the reason attached. Not a template with your name on it.
Thu
Third session of the week. Bench goes up 2.5 kg because last week closed at 6, 6, 6, 6.

A name and a rep scheme are no use if you have never done the movement before. So every exercise the coach writes carries a video demonstration and the cue that matters for it: the tempo, the progression rule, the pace. Watch it once, at the rack, and get on with the set. Ask, and the coach talks you through the movement.
Every fitness app eventually hands you a screen to fill in. Here is the complete list of things RepX never asks you to do.
You say it. That is the entire interface.
The coach sets a type on every exercise it writes, and the type is what decides how the app tracks it. That is why a swim, a metcon and a back squat can sit in the same week without you configuring anything.

Exercise type decides what is tracked
You get exactly one training plan, and you keep it. The coach holds a rolling window: the last thirty days as a record of everything you actually did, the next thirty already written. It pushes that window forward as you go. Nothing expires, and there is no replacement to choose.
A knee, a race, a week with no gym. When something changes, the coach reshapes the same plan forward. What you have already done stays exactly as you did it.
Every other app gives you a barcode scanner and a database. RepX gives you a sentence. Diet is the one thing that is updated only through conversation. There is no food-logging screen anywhere in the product. If a sentence is too much, a photo of the plate will do.

“two eggs, black coffee, and a banana on the way to the gym”
Coach
Logged. 14 g protein, 232 kcal. 828 kcal and 56 g protein left today.
1,512 / 2,340 kcal
Tell the coach what is in the fridge, or just what you are short on today. It writes a whole-food dish that lands inside what you have left — calories and macros — with the ingredients and the method. Say “save it” and it keeps the recipe, with its nutrition facts as a share of your own day.
You
“what can I cook tonight with what I have left?”
Coach
You have 828 kcal and 56 g protein left. Lemon chicken, rice and broccoli: one pan, about 25 minutes, 630 kcal and 56 g protein for the whole plate, which closes protein exactly. Say “save it” and it stays in your recipes.
Saved
High protein, one pan, about 25 minutes. Sized to what was left on Thursday.

Send the coach a photo, up to three in a message. Your lunch, and it estimates the plate and logs it. The bottom of your squat, and it coaches the movement. A machine you have never used, and it tells you what it trains, how to set it up, and where it fits in your week.

“bottom of my squat, is the depth ok?”
Coach
Below parallel, back neutral, knees tracking over the toes. Depth is fine. If the heels lift on the next set, take 5 kg off the bar.

“what is this machine, can I use it today?”
Coach
A pendulum squat: quads and glutes, the same pattern as your back squat. Feet mid-plate, brace, sit straight down. 3 × 10 at a moderate load today, and say so if you want it in place of Monday’s squat.
Everything you tell the coach becomes your record: days closed, sessions done, your weight, calories and protein against target. Statistics reads it back over four weeks, eight weeks, six months or a year, and your day streak sits on every screen. Nothing to fill in, nothing to keep up to date.
Weekly completion
Right now
Seven days of the whole thing: the coach, your plan, your macros, the recipes, your stats, every video. Make an account and it starts working. Stay on, and the year saves you $49.89 over paying monthly.
Takes about a minute.
No. 7 days free, no card, no billing details. Create an account and the coach starts working. If you do not come back, nothing happens and there is nothing to cancel.
RepX Pro is $9.99 a month or $69.99 a year. One tier, everything included. There is no upsell and no feature held back.
No. The coach programs whatever you are training for: lifting, running, swimming, CrossFit, HYROX, or a hybrid week that mixes strength and endurance. There is no discipline to pick, because the coach sets the type of every exercise it writes.
RepX runs in your browser, so there is nothing to download from the App Store or Google Play. It is built phone-first. The usual place to open it is in the gym, between sets.
Yes. Statistics shows what you actually did over four weeks, eight weeks, six months or a year: days closed, sessions done, weekly completion, your weight, calories and protein against target, and your day streak. It is built from what you tell the coach, so there is nothing to fill in and nothing to keep up to date.
Both. If you have never written a workout plan, the coach writes one and shows you a video of every movement in it. If you already know what you are doing, the point is that programming and tracking stop costing you spreadsheet time. It is the part of a personal trainer that plans your week, without the hourly rate.
Every exercise the coach writes comes with a video demonstration of that movement, pulled from YouTube and attached to the exercise itself, with a one-line cue beside it. You watch it in the workout, before the set. If you want more, ask the coach and it talks you through the movement.
You tell the coach. “Squats felt heavy, only got four on the last set.” “Two eggs and a black coffee.” Or you send a photo of the plate. It updates your history and your macros from the sentence or the picture. There is no logging screen, no food diary and no barcode scanner.
Yes, up to three in a message. A plate of food, a packet or a menu, and it estimates the calories and macros and logs them. The bottom of your squat, and it coaches the movement. A machine at the gym, and it tells you what it trains and how to set it up. It reads plates, kit and form, and never comments on how you look.
Yes. Ask what to cook and the coach writes a whole-food dish that fits the calories and macros you have left today, with ingredients, quantities and method. Say “save it” and it goes to your Recipes with its nutrition facts against your own targets. Log a portion of it later by saying so.
Write it down once, in your own words, when you sign up. You can change it any time in settings. The coach factors it into every plan, workout and exercise it writes from then on.
There is nothing to edit. Tell the coach what you want different and it reshapes the same plan forward. You never build a plan, and you never start a new program.
English, Serbian, Spanish and French, in the app and on this site. Tell the coach anything in your own language and it answers in it.
Tell the coach what you are training for, in your own words. It writes the rest before you have put your shoes on.
