The workout recap: new records, and how strength and volume moved

It's the real app — tap anything

How it works

  1. 1

    Train

    Tick each set — weight and reps are already logged.

  2. 2

    PRs on their own

    At the end of the workout you see what you beat — 1RM, weight, reps or time — against your whole history.

  3. 3

    Watch the trend

    Each exercise's stats: the ≈1RM chart, records and volume for a week, a month, a quarter or all time.

What's inside

The Epley formula

1RM = weight × (1 + reps / 30). A single is the max itself; sets over 12 reps count as 12 so the estimate doesn't run high.

A calculator in the app

It opens with the period's best set: the load for 1–12 reps and a 95–50 % table, in 2.5 steps. “Use this” puts the weight into the set.

Records by the main metric

1RM and weight for strength lifts, reps for bodyweight sets, time for a plank.

Where you see them

In the workout recap, on the “Workouts logged” card, in your stats and on the page you share by link.

Questions

How is the 1RM estimated?

With the Epley formula: weight × (1 + reps / 30). For example, 100 kg × 5 = 116.7 kg. A single is the weight itself; over 12 reps counts as 12.

Do I need to test my max?

No. The estimate comes from your regular working sets — no heavy single needed.

Why didn't my PR count?

A record means beating the lift's whole history on its main metric: 1RM or weight for a barbell lift, reps for pull-ups, time for a plank. Matching your previous best isn't a record yet.

Can I estimate my 1RM without the app?

Yes — with our 1RM calculator on this site: the same formula as the app, plus a percentage table.
