FITNESSGRID VS STRONG
FitnessGrid vs Strong
Strong is the classic, no-nonsense lifting logbook. FitnessGrid keeps that simplicity for logging — and adds the coach that decides what the week should be.
Strong earned its reputation by being simple. Open it, log your sets, see your history and PRs, leave. No clutter. For lifters who already have a program and just want a reliable place to record it, that simplicity is the whole point.
FitnessGrid keeps logging that simple — tap a set, log weight, reps, RPE — and adds an AI coach that builds the program for you. The coach plans your week, reads what you actually lifted, and adapts the next one. It also tracks nutrition in the same app. Strong records the work; FitnessGrid plans the work and then records it.
WHY PEOPLE SWITCH
What you get by moving over
You do not need a program first
Strong assumes you already have one. The coach builds your week from your goal — no template hunting before you can start.
The plan reacts to your log
Strong's templates hold still. The coach reads RPE, missed sessions, and PRs, and adapts the next week accordingly.
Nutrition is included
Log meals in plain language next to your sets. The coach plans food and training as one system, not two apps.
Same simplicity, less deciding
Logging stays as fast as Strong. What goes away is the mental load of programming the week yourself.
Where Strong still wins
No tool is the right call for everyone. The honest version:
- Pure simplicity. Strong does one thing and does not get in the way. If you want zero surface area beyond a logbook, that minimalism is a genuine strength.
- Maturity. Strong has been around a long time, is stable, and has a large, loyal user base — a newer app cannot match that track record yet.
- If you already run a fixed program you trust and have no interest in an AI coach reshaping it, Strong's hands-off approach suits you better.
