FitnessAI

FitnessAI is a strength-training app for iOS and Android that programs sets, reps and weights with AI, adapts to your equipment and recovery, and tracks progress for gym-goers and home lifters.

What is FitnessAI?

FitnessAI is a strength-training app from FitnessAI Inc. that uses an algorithm to plan your workouts. Instead of following a fixed program, you tell the app your goal, schedule and available equipment, and it prescribes the exercises, sets, reps and weights for each session, then adjusts them as you log your results. More information is on fitnessai.com.

It is designed for people who want structured progressive overload without hiring a personal trainer, from beginners learning gym basics to experienced lifters who want data-driven progression.

Key Features of FitnessAI

AI-programmed sets, reps and weights

The core feature is automatic programming. The app tells you exactly what to lift and raises or lowers the load based on how your previous sessions went, aiming for steady strength gains. The company says its model is built on a large dataset of logged workouts.

Flexible session length and equipment

Workouts can run from 5 to 30 minutes and adapt to the equipment you have, whether that is a full gym, a home setup or a hotel room. Exercises can be swapped instantly when a machine is busy.

Adaptive recovery

FitnessAI monitors performance trends and eases off intensity when you seem fatigued, or pushes harder when you are progressing quickly.

Guided exercise demos

Each exercise includes guided videos and muscle visuals to help with form, which is useful for beginners trying new movements.

Progress and body composition tracking

The app tracks strength gains over time and offers body composition tracking, including a 3D BodyScan visualisation, so progress is not judged by the scale alone.

Apple Watch and Apple Health

On iPhone, workouts sync with Apple Health and the app supports Apple Watch for logging training data. Structured challenges with rewards are also offered for extra motivation.

FitnessAI Pricing

FitnessAI is free to download on iOS and Android and is monetised through in-app memberships. The official website does not publish a price list, so the figures below come from the in-app purchase list on the US App Store. Several prices appear for similar terms, which usually means different offers or regional tests; the price you see in the app may differ.

The website was also showing a banner for a 10% discount code, but no actual code was displayed, so we do not list one here.

Prices checked on October 27, 2026; check the official pricing page for current plans.

Who Should Use FitnessAI?

• Gym beginners who want a clear plan instead of guessing weights.
• Busy people who can only train in short 5 to 30 minute sessions.
• Lifters who want automatic progressive overload tracking.
• Home or travel exercisers working with limited equipment.
• Apple Watch users who want workouts synced to Apple Health.

Is FitnessAI Worth It?

FitnessAI is a focused tool: it does one job, programming strength workouts, and does it with minimal effort from the user. Automatic adjustment of weights and reps, equipment-aware exercise swaps and short session options make it easy to stay consistent, and the guided demos help newcomers learn proper movement.

It is less suited to people who want nutrition planning, detailed cardio programming or the ability to design every exercise themselves. Pricing is also not transparent on the website, with several in-app price points for similar memberships, so check the offer carefully before subscribing and remember that App Store subscriptions renew automatically. The app is a training aid, not medical advice, so anyone with injuries or health conditions should consult a professional first. For lifters who value structured, data-driven progression, FitnessAI is worth trying.
