Where StrongLifts wins
For a brand-new lifter running 5×5, StrongLifts is about as simple as it gets. It's the right pick for total beginners running their first linear program.

That's the difference between an app that records or suggests training and one that actually programs and autoregulates it for you — for a fraction of the price of a human coach.

For a brand-new lifter running 5×5, StrongLifts is about as simple and foolproof as it gets. The catch is that linear progression stalls within months — and that is exactly where Gymex picks up, with real periodisation, RIR autoregulation and plateau detection.
Is StrongLifts or Gymex cheaper?
StrongLifts runs from free to about £8/month; Gymex is free to start with paid plans from £7.50/month. The entry prices are similar — Gymex simply keeps working long after 5×5 stops.
Can Gymex replace StrongLifts?
Yes — Gymex can run a beginner linear progression and, more importantly, carries you past it: when adding weight every session stops working, it switches to periodised progression instead of leaving you stuck. StrongLifts has no answer to that plateau.
What does Gymex do that StrongLifts doesn't?
Gymex programs beyond linear: multi-week blocks with deloads, RIR-based load adjustment, plateau and overtraining detection, voice logging and nutrition. StrongLifts does simple linear programs brilliantly — and little beyond them.
