Building My Future: Gimnasio

A gym trainer in your pocket: Building My Future guides your workout live, tracks your weights and sets, and tells you when to increase the weight. No accounts, no cloud storage, no ads, and no internet connection: it works entirely on your phone.

It's not a list of exercises you tick off. It guides your session and learns from what you lift.

GUIDES YOU WHILE YOU TRAIN
• Rest alerts you even with the screen off. It rings and vibrates even if your phone is in your pocket, and the countdown appears on the lock screen with a button to skip to the next set without unlocking.

• Each set has its weight and reps, pre-set from the plan: you only need to adjust them on days when they're not included.

• Real supersets and circuits: the exercises are linked one after the other, and the rest period begins at the end of each round, with its own countdown.

• "Machine occupied": pushes that exercise to the end and lets you move on to the next one without losing your place.

• Get the machine ready: During your rest, prepare the weight for the next set.

IT TELLS YOU WHEN TO INCREASE THE WEIGHT, AND WHY
• When you complete all your sets above the target weight range, it suggests increasing the load, reflecting the actual weight increase on the machine, and explains the reason below.

• And it tells you when to decrease the weight: If you've been stuck on an exercise for three sessions, it suggests reducing the weight by 10% to help you progress from there. This is half the weight that almost no one does on their own.

Warm-up sets are recorded but don't count towards your total, so they don't skew your numbers.

• This progression of weights is the difference between going to the gym and actually training: Without it, you'll be lifting the same weight for months.

YOUR TRAINING LOG, WITHOUT WRITING IT
• Each session is saved with its exercises, weights, and reps, set by set.

• Muscle map: what each exercise works and, above all, what each muscle has been working this week. It's the only thing that tells you if you're maintaining a consistent workout or haven't trained legs in three weeks.

• Estimated strength (1RM), because just the weight is misleading: 40 x 12 and 50 x 5 are almost the same effort.

• Streaks, records, weights lifted, and a heat map of your consistency.

THE PLAN IS YOURS
• It comes with a 100-day challenge and eleven additional routines—strength, hypertrophy, full body, upper/lower body, home workout—but you can bring your own, written in Markdown or JSON, or create it within the app.

• Each plan saves your progress separately: you can switch between them without losing anything.

• Reminders: tell it which days and times you usually train, and it will notify you when your workout is due. If you've already trained that day, it won't bother you.

ON YOUR WRIST
• With Wear OS, you log your workout from your watch, while your phone is in your locker.

• Integrates with Health Connect: each workout is saved with its duration and details of exercises and weights.

YOUR DATA IS YOURS
• There are no accounts, no registration, no server, no ads, and no analytics. It doesn't even ask for internet access.

• Everything stays on your phone, and the app includes its own backup: save a file wherever you want and restore it to another phone exactly as it was.

WHO IS IT FOR?
For anyone who goes to the gym and wants to stop writing down sets in their phone's notes app. It works just as well whether you're a beginner—the 100-day plan guides you—as if you already train and just want a weight tracking system to tell you when to progress. It's also great for home workouts, with dumbbells or bodyweight exercises.
