The All Exercises section gives you access to the full exercise library.
Selecting an exercise brings up its full details: a precise description of the movement, technique cues and key points to keep in mind for effective and safe training.
Beyond the description, you'll also find your personal stats for that exercise: weight progression, rep counts and how you've improved over time, regardless of which session it was part of. A complete log of all your performances on that exercise is available there too.
To find an exercise faster when building your programs, tap the star next to its name to add it to your favorites. Favorited exercises automatically move to the top of the list every time you search.
