Everything you can build, track, and adapt with your AI trainer.
When you first open the app, Carlos doesn't know anything about you yet. The more you tell him upfront, the better your workouts will be from day one.
Your experience level, goals, injuries, and available equipment all shape what Carlos builds for you. If you have a bad knee, Carlos won't program deep squats. If you only have dumbbells at home, he won't suggest cable exercises.
If you work out in different places — a commercial gym, a home gym, a hotel when traveling — add each one as a location with its available equipment. You can do this in Settings, or just tell Carlos:
Carlos uses your locations to make sure he only programs exercises you can actually do.
Link Strava, Garmin, or Apple Health so Carlos knows about your runs, rides, and other activities. This way he can adjust your strength training around what you're already doing.
Go to the Home tab and start chatting. Be specific about your goals, schedule, and preferences.
Example prompts to get started
Carlos will build you a full program with routines, exercises, sets, reps, and rest times — all based on what you told him.
Most workout apps give you a routine and expect you to follow it forever. Let's Gooo is different — your training adapts to your life, not the other way around.
You're never stuck with a workout that doesn't fit today. Your routine from last week was designed for last week. Today is different. Maybe you did a big bike ride yesterday. Maybe your lower back is tight. Maybe you only have 30 minutes instead of an hour. Maybe the workout has gotten too easy.
Instead of pushing through or skipping the gym entirely, open your routine and tell Carlos what's going on:
I'm still sore from Monday's leg day·
My shoulder is flaring up today·
I only have 30 minutes·
I went on a hard 50-mile ride yesterday, go easy on my legs·
This workout has gotten too easy — make it harder·
I don't have access to cables today
Carlos knows your routine, your recent training, and your history. Based on what you tell him, he'll either:
You can see all versions of a routine right on the routine page. Over time, you might have your standard Push Day, a home version, a quick version, and a deload version — all branched from the same base, each with its own workout history.
This is what makes the app different. You aren't following a static plan. You're having an ongoing conversation with a coach who adapts with you — session to session, week to week, month to month.
A program is a collection of routines that work together as a training plan.
Your routines cycle endlessly — do routine A, B, C, then back to A. Great for ongoing splits with no end date.
Try
Training that progresses over a set number of weeks. Each week has its own routines, and the app advances you automatically.

A routine is a single workout — a list of exercises with sets, reps, rest times, and coaching notes.
Carlos builds routines based on your available time, equipment, goals, and any injuries or limitations.
Try
Two or more exercises performed back-to-back with no rest between them. You rest after finishing the group. Shown with an orange header during your workout.

Try
Link a stretching routine before or after your main workout.

| Type | What it means |

| Working | Your main work sets (default) |
| Warm-up | Lighter prep sets — excluded from volume stats |
| Drop set | Reduced weight immediately after a working set |
| To failure | Taken to muscular failure |
| AMRAP | As many reps as possible |
Rate of Perceived Exertion (1–10 scale) — how hard a set felt. Enable in Settings. Carlos uses your RPE data for smarter progression suggestions.
Automatically detected during your workout:
PRs are celebrated with visual feedback when you log the set.
305 built-in exercises, each with form instructions, cues, common mistakes, muscle groups, and video links. You can also create your own custom exercises.
When you ask Carlos about form or technique, he may save a note on that exercise. These notes appear automatically the next time you do that exercise in a workout.
Enter your weight and reps, then mark the set complete. The app auto-fills from your last session so you can tap through quickly if nothing changed.
Modify your workout on the fly without changing the routine template — swap an exercise, adjust rest times, or skip an exercise.
Try
Before you start, Carlos reviews your recent training and suggests target weights, things to watch for, and how this session fits into your week.
After you finish, Carlos analyzes your session — volume changes, PRs, recovery notes, and suggestions for next time.
Bring your history from other apps:
| Source | How |
|---|---|
| Hevy | Export CSV from Hevy, import in Settings |
| Strong | Export CSV from Strong, import in Settings |
| Paste | Copy/paste a workout from anywhere |
| CSV | Upload any structured CSV file |
Imported exercises are matched to the built-in library automatically.
When an external activity overlaps with a workout you logged, they're automatically linked — giving you a combined view with set data and heart rate / effort metrics.
On your home screen, Carlos suggests which routine to do today based on muscle recovery, recent training, external activities, your frequency goals, and weekly progress.
