What it is
A personal trainer usually runs the business with spreadsheets, scattered chats and loose notes: who paid, whose plan expires, which routine each student is on. Trainer puts all of that in one panel that works from the phone, the tablet or the computer.
Each trainer gets a public portal at trainer.ar/their-nickname with their own logo, payment methods and social links. Students log in there and see their routine, nutrition and supplementation, log their progress and keep up with payments.
Watch the demo
Two roles, one platform
Manages students, routines, nutrition and supplementation, sees who paid and who is due, and shares the portal link. Sidebar on desktop, bottom navigation on the phone.
Enters through the trainer's portal and sees their plan: routine by day, nutrition, supplementation, measurements and stats. A minimal layout, made to be used at the gym.
What a trainer can do
Register fees and see who paid, who owes and when each plan expires. After a grace period, overdue accounts are blocked automatically every day.
A routine per student, day by day, with an exercise library with images, observations, and copying routines from another student.
A drag-and-drop board of the week: move exercises between days, combine them into supersets and edit each one in a side panel.
Generates a complete routine from the student's objective, measurements and training days, ready to edit.
A rich text editor with images, links and YouTube videos. Students see a clean, read-only version.
trainer.ar/your-nickname with your logo, payment methods and social links: the link your students use to log in.
The student is notified when their plan changes; the trainer, when the student logs progress or measurements or updates their profile.
Weight, reps, time and effort (RIR / RPE) per exercise, body measurements over time, daily nutrition and supplementation check-ins, and charts.
Invite another trainer with your link: when they subscribe, both pay 50 % less for 3 months. You follow your commissions and payouts from your own panel.
Large buttons and bottom navigation on the phone, a sidebar on desktop. The same account works everywhere.
Sign in with email or Google, protection against bots and repeated login attempts, and every piece of content is cleaned before it is shown.
The state of every student at a glance: active, about to expire, overdue and blocked.
How it works
A three-step wizard: your details, your brand (nickname and logo) and how your students pay you. No card needed.
Each one gets their own access. Build their routine, nutrition and supplementation, or copy them from another student.
Students log in at trainer.ar/your-nickname, see their plan and log their progress from the gym.
Payments, due dates, notifications and stats update as you and your students use the platform.
Nothing to install and always the latest version: Trainer runs in the browser, and the layout adapts to each screen.
Plans
The free plan includes every feature with up to 5 active students, without a card. Paid plans add more students for a simple monthly fee, paid by Mercado Pago or bank transfer, with no contracts: the platform takes care of due dates, blocking and discounts.
