Strength training log
A gym log that does the percentage math for you
Plan sets by % of 1RM, RIR or rep range, log what you actually lifted set by set, and keep every 1RM test on record — so your next block starts from real numbers.

- % of 1RM → exact weight
- 1RM history for every lift
Prescribe it once, log it honestly
Every set can have its own target. On the gym floor you see exactly what to lift — and record what really happened.
What gets logged
- Reps and weight for every set
- Missed reps — not just “done”
- Notes for next time
- 1RM tests that update your working weights
- Plan vs. actual, visible to your coach
Prescribe
Program every set the way you think about it
Switch between reps, rep range, to failure or RIR, and set the load in kg, lb or % of 1RM. Write a straight 5 × 5 in one row, or open per-set details for pyramids and waves.
- Per-set reps and load
- % of 1RM, RIR and rep ranges
- Supersets share the set count

Frequently asked questions
How does vZali calculate weights from % of 1RM?
It takes your most recent 1RM result for that exercise — from a 1RM test logged in the app — and applies the percentage to each set. Log a new max and future sets update automatically.
What if I don’t know my 1RM?
Estimate it with the free 1RM calculator from any set of 1–12 reps, or log a 1RM test in the app. Until a max is on record, the set shows the percentage only.
Can I prescribe RIR or rep ranges?
Yes. Choose reps, rep range, to failure or RIR for each exercise. Athletes then log the reps and weight they actually did.
Does it work for supersets?
Yes. Exercises in a superset share the set count and are logged round by round.
Do I need an account for set-by-set logging?
Yes — a free account. Guest mode covers programs, the timer and overall results; per-set logging and 1RM-based weights need an account so your history is saved.
