GZCLP, week 1, worked out by Catalyst for an example lifter.
How it works
The best programs are precise: percentages, stages, deloads, resets. Catalyst follows them to the letter, so you never open a spreadsheet again.
Strength, muscle, powerlifting, running, conditioning or mobility. Every program is explained before you start: its schedule, its sets and where it takes you.
Find yoursA recent set or a max for each lift. Catalyst turns them into your starting weights exactly the way the program says to.
Every set, weight and rest is ready when you are. Log a set with one tap; when you finish, the program’s own rules decide what comes next.

Inside the app
Add weight, change stage, deload, retest: each program’s own rules run after every workout, so the next one is always right.
Log a set as prescribed in a single tap, or adjust the reps and weight. Corrections never rewrite your history.
The rest after each set counts down where you can see it, and tells you when it’s time for the next.
See which plates go on each side of the bar, with warm-up sets that build to your first working set.
Every workout kept, every lift charted from your first session to your last, with your records as they fall.
No account needed and no signal required. Your training stays on your phone, and you can export all of it at any time.
