Workout log
Only what matters at the gym. Two taps per set.
The workout screen is the heart of SimuFit. Weight is prefilled from last time, the rest timer starts on its own, and you see straight away when it’s time to add load.
- Works offline – your logs sync later
- Rest ring, +30 s and a buzz when it’s time to go
- Last time’s numbers and a progression hint on every exercise
- Machine taken? Swap to a similar, no-equipment or easier option

AI program
AI proposes. Rules verify.
Your program is built from a detailed profile and uses only exercises from the curated library. Before you see it, it passes automatic checks: volume, recovery, session length and exercises that suit your limitations.
- Phases, deload weeks and RIR targets
- Respects injuries, equipment and schedule
- Ask for changes in your own words: “fewer leg exercises”

Progressive Overload: How to Keep Getting Stronger
Progressive overload is the core principle of strength training: your training has to ask a little more of you over time, or your body has no reason to keep adapting. This guide shows how to apply it without guesswork.

What is SimuFit?
SimuFit is a strength-training app that combines a personal training program, a fast workout log and clear progress reports. An optional nutrition mode calculates daily targets and suggests meals.
Do I need to install anything?
No. SimuFit runs in the browser on your phone, tablet and computer. If you like, add it to your home screen: it then opens like a normal app and also works offline.
Is SimuFit good for beginners?
Yes. The questionnaire takes your experience into account, and every exercise has a short video, coaching cues and common mistakes. There are also ready-made beginner programs.
How safe are AI-generated programs?
The AI may only use exercises from the curated library, and every program is checked by automatic rules before you see it. The health questionnaire switches to a more conservative program when needed. SimuFit is not a medical device, though.
Does SimuFit work for home workouts?
Yes. Choose dumbbells only or bodyweight only as your equipment. Every gym exercise also has a no-equipment alternative.
Which languages does SimuFit support?
Finnish, English and Persian. Persian is shown right-to-left with Persian digits, and the AI answers in the language you choose.
Ready to start? Your first workout in under three minutes.
Answer a few questions, get your program, and the workout screen is ready for the gym. Runs in your browser: no app store, no install.
