Getting Started.
Setting up Checkfit and your first week.
What is CheckFit? +
CheckFit is an AI training partner for serious lifters. It builds your program, gives you exact targets for every set, and progresses the plan week to week based on what you actually lift.
What platforms is CheckFit on? +
iPhone. Android and web are not available yet.
How do I get started? +
Download the app and answer a few questions — experience, goal, equipment, and how many days you want to train. CheckFit builds your first program in about a minute.
Do I need a gym membership? +
No. Tell CheckFit what you have — a full gym, dumbbells only, or just your bodyweight — and it builds the program around that.
I'm a complete beginner. Is CheckFit for me? +
Yes. Your program starts conservative, every exercise comes with form cues, and the progression system moves at the pace you earn.
I've been lifting for years. Will this still challenge me? +
That's who it's built for. Set your experience honestly during onboarding and the program loads accordingly — the double-progression system doesn't care how advanced you are, it always asks for one more rep.
How long are the workouts? +
Most sessions run 45–75 minutes depending on your program. Each workout shows an estimated duration before you start.
Can I choose which days I train? +
Yes — pick your training days when you create a program. The schedule is built around them.
How is CheckFit different from a workout logger? +
A logger records what you did. CheckFit decides what you should do next — every set has a target, and next week is written automatically from this week's performance.
Do I need an Apple Watch or other gear? +
No. Everything runs from your phone.
