What it does
Strong is a workout tracker for iPhone, Android and Apple Watch. It lets users plan training, record sessions, review exercise progress and export their data. Strong PRO adds further progress views.
Use Strong when you already have a routine and want a record of what happened in each session. Begin with the exercises you actually perform, then keep the entries consistent enough to compare later workouts. Its purpose is close to a gym notebook rather than a library of video classes.
The site describes access across supported devices and data export, which are useful considerations for a long-running training history. Free accounts are advertised. Review the current PRO feature division before choosing an upgrade for a particular chart or measurement.
The free version can save three workout templates. Strong PRO removes that template limit. Templates hold exercises and sets as a starting point; they are separate from completed workouts and can also be saved from a session in History.
Strengths
- A notebook-style workflow centers on recording an existing routine.
- Data export provides a way to retain training records.
Best for
