▶ Start
Training well shouldn’t be a privilege.
Consistency isn’t lost for lack of motivation: it’s lost for lack of a plan that adapts to you, your week and what you have at hand.
WhatsApp, Excel and PDFs, and platforms that take a cut and erase your brand. Programming well shouldn’t cost you your identity.
Nobody solved both sides at once. Fittrena does.
How the AI trains with you
Tell it who you are
Goal, level, injuries, days, gear, and whether you train at home or at the gym. Once, no typing.
Every day, your workout ready
Built on your records, your history and this week’s fatigue. Swap an exercise or today’s focus with one sentence.
Train on the board or in Play mode
Timers, rounds, sets ticked with a tap, timed rest and your watch on your wrist. When you finish, it celebrates and shares.
AIAnything a human didn’t program carries the AI label. You always know who signs your workout.
What it does for you
Today, as a list
One or several workouts a day, each signed by whoever programmed it: the AI, your specialist or your coach.
Multi-week plans
Phases, weeks and days on a fixed calendar. Run several at once: kettlebell Monday and Wednesday, running Tuesday and Thursday.
Specialist AI coaches
Pick a generalist or a specialist with their own method: kettlebell, running, yoga, CrossFit, calisthenics, hypertrophy or HIIT.
Nutrition that respects you
Macros tailored to you, recipes and logging with a photo of your plate. Tell it your allergies once: it never skips them.
Your watch, included
Native apps for Apple Watch and Wear OS, plus heart rate and calories from Apple Health and Health Connect.
Repeat and adjust
Go back to a past workout, change the loads with last time’s reference and schedule it for any day you want.
History and records
Streak, consistency, personal records and an exercise library with video inside the app.
Share what you train
Story, square or sticker with your workout, your week or your record. No personal data, with your brand and your coach’s.
Choose who coaches you
Every AI coach has a method: their formats, their progressions and what they would never program. Pick one when creating a plan or a workout, or let Fittrena build it in general.

And whenever you want, a real one
Link with your coach by code or from the directory. They program by hand or with the AI at their side, and their brand travels in every workout you do.
14 days free, no card
You decide what they see, category by category.
Verified reviews: only real clients can rate.
Their plan and your AI plan coexist: nothing forces you to choose.
No store fees: the coach pays per client slot and the client never pays for the app.
Quick questions
Does it work at home with no gear?
Yes. The AI only uses what you have: bodyweight, a band or a kettlebell. If something’s missing, it substitutes and tells you why.
Can I use it without a coach?
Of course. Most people train with the AI alone. A human coach is optional and can be added whenever you want.
What about my injuries?
You tell it once and they become a safety rule, not a preference. No workout ignores them.
Which languages?
Spanish, English and Portuguese, in the app and in emails.
And my data?
It’s yours. Sharing on social never includes personal data, and with your coach you choose what they see, category by category.
Tomorrow’s workout is already planned.
You just show up.
