FitnessAI: Gym Workout Planner

The core of FitnessAI is its suggestion engine. For every exercise you see a weight and rep range pulled from your own history plus the wider training data. Log a set that felt easy and the next one gets heavier. Struggle and it backs off. This is the part that separates it from a static spreadsheet plan, since the numbers move with you instead of staying fixed.

You tell the app what you have, whether it's a commercial gym, a pair of adjustable dumbbells, or nothing but floor space. The exercise selection and swaps follow that list. If a machine is busy or missing, you can swap a movement and keep the session on track. It's the feature that makes the same app work for a crowded gym and a small apartment.

FitnessAI connects to Apple Watch and Apple Health for automatic logging. Start a workout and your watch can track sets and rest periods without you reaching for the phone. The synced data also keeps your training history in one place, which matters because the algorithm leans on that history to set your next weights.

Each exercise comes with guidance on form, and the app shows which muscles a movement targets. For lifters still learning an exercise, that visual layer is a faster way to check you're working the right area. It won't replace a coach watching your rep, but it covers the basics before you load up the bar.

The app tracks more than the number on the scale. A BodyScan view is meant to show changes in muscle and fat over time, so progress you can't feel in a single session still shows up over weeks. It pairs with the strength charts, giving two angles on whether the plan is working.

FitnessAI runs focused challenges with rewards attached. They're aimed at consistency, the thing most lifters lose first. A challenge gives a short term target beyond your normal rotation, which can pull you back to the gym on days you'd otherwise skip.
