AI personal trainer app

An AI personal trainer for strength training.

What it is

Workout tracking, programming, and coaching in one loop.

Brace AI is built around the full training cycle: plan the workout, log what happened, review the result, and adjust the next session. That is the gap between a static workout app and an actual coach.

A real program

Your week is planned around your goal, schedule, experience, and equipment.

Fast workout logging

Track sets, reps, load, effort, rest, and PRs without losing focus mid-session.

A coach thread

Ask about soreness, swaps, missed sessions, or why the next workout changed.

Progression handled

Load and rep targets adjust from what you actually lifted, with coach guidance when fatigue or stalls need a back-off.

How Brace AI coaches you

The app is not just a chat box and not just a workout generator. It follows the same loop a coach would use week after week.

01

Tell the coach what you want

Goals, training age, injuries, equipment, schedule, and how hard you want to be pushed.

02

Get a training block

The app builds a 2 to 3 week strength block instead of handing you a random workout.

03

Log the session

Record sets, reps, load, effort, swaps, and rest from your phone. Apple Watch support is in development.

04

Let the plan adapt

After each workout, the coach adjusts the next session from your logged load, reps, effort, and missed-workout context.

An iMessage-style coach thread, built into your training

The coaching layer is designed to feel like a real trainer conversation: quick questions, specific debriefs, and practical changes when life interrupts the plan. The app is where you train; the coach thread is where the relationship lives.

  • Morning nudge when today is a training day
  • Post-workout debrief based on the sets you actually logged
  • Equipment swaps when you train at a hotel or home gym
  • Soreness and injury adjustments before the next session
  • Missed-session follow-up that reshapes the week

Progressive overload without spreadsheet guesswork

Brace AI tracks sets, reps, load, effort, volume, and recovery patterns. Then it changes the next workout like a coach would: push when you are ready, hold when form breaks, or back off when fatigue is winning.

  • Double-progression style load and rep targets
  • Per-muscle volume and recovery signals
  • Back-off guidance when effort outruns progress

Everything you need at the rack

Strong and Hevy win by being easy to log in. Fitbod wins by reducing planning. Brace AI needs both, plus coaching that follows through after the set.

Training flow

Built for messy real gyms, not perfect Wi-Fi.

The best workout tracker is the one you can use while tired, sweaty, and between sets. Brace AI keeps phone logging fast, stores workouts offline, syncs once your signal comes back, and is being designed with Apple Watch as the workout-floor companion.

Apple Watch Offline tracking

Built for lifters who want to progress

Returning lifters

Back after time off and need a plan that meets your current strength, not your old numbers.

Intermediate lifters

Past beginner gains and need progression, deloads, and better decisions between sessions.

Home and garage gyms

Limited equipment, weak signal, no coach on site, and no patience for guesswork.

Busy schedules

Miss a session, travel for work, or train on odd days and the coach reshapes the week.

How Brace AI compares

Worth keeping on the homepage, but not as a thin feature checklist. The important question is what job you need the app to do.

Versus a workout logger

Loggers like Hevy and Strong are great if you already know your program. Brace AI keeps the logging, then adds the coaching decisions on top.

 Brace AI vs Hevy

Versus a workout generator

Generators can build today's session. Brace AI is built around a longer coaching thread, training block, debriefs, and plan changes over time.

 Brace AI vs Fitbod

Versus a spreadsheet

Spreadsheets can progress a lift on paper. Brace AI reacts to missed reps, fatigue, equipment changes, and what your week really looked like.

Frequently asked questions

Is Brace AI available?
Brace AI is in private iOS testing. The public App Store listing is not live yet, so use this site for product details and join the update list when you want to be notified.
What is Brace AI?
Brace AI is an AI personal trainer and workout tracker for strength training. It builds your program, lets you log every set, adjusts your next workout, and gives you a coach-style chat thread for questions, debriefs, and check-ins.
How is Brace AI different from Hevy or Strong?
Hevy and Strong are excellent workout loggers if you already know what to do. Brace AI is built for people who want the app to write the program, explain the plan, and progress workouts from their logged performance.
How is Brace AI different from Fitbod?
Fitbod is strongest as a workout generator. Brace AI is designed more like a coaching relationship: a plan over time, a persistent coach thread, post-workout debriefs, and changes when your schedule, equipment, soreness, or injuries change.
Do I need to know how to program my own workouts?
No. Brace AI builds your program from a short setup chat about your goals, experience, schedule, and equipment. You can still edit any session, swap exercises, or tell the coach to change the plan.
Does Brace AI support Apple Watch and offline logging?
Brace AI is iPhone-first, with Apple Watch support in development as the workout-floor companion. Offline workout logging keeps completed sessions moving; chat, swaps, and cloud sync resume when you are back online.
Is Brace AI free?
You can set up your profile, get a program, and log workouts for free. A subscription unlocks unlimited AI coaching, advanced progression, long-term analytics, and deeper follow-up.
Is Brace AI good for beginners?
Yes. Beginners benefit most, because the app removes the hardest part: deciding what to train and when to progress. It builds a structured plan, explains each session in plain language, and adjusts as you learn the lifts.
Can an AI app replace a personal trainer?
For programming, progression, and day-to-day questions, Brace AI does the same job a remote coach does, at a fraction of the cost. For hands-on, in-person technique coaching, a human trainer still has a place.
Does Brace AI work for home and garage gyms?
Yes. You set your available equipment during setup, and the coach programs around it, whether that is a full rack, adjustable dumbbells, or bands. Offline logging means a weak garage signal never interrupts a session.
What equipment and goals does Brace AI support?
It supports strength, muscle gain, and general fitness goals across barbell, dumbbell, machine, and bodyweight setups. You can train at a commercial gym, a home gym, or while traveling, and the plan adapts to what you have.
