Your records for each exercise

The records Musku tracks

• max weight: the heaviest load lifted;
• estimated 1RM: your theoretical one-rep max;
• set volume: load × reps;
• max reps: your highest number of reps, for bodyweight and resistance bands.

For cardio, Musku keeps your longest distance and your longest duration.

A trophy the moment it happens

During a workout, as soon as a set beats a record, its pill turns into a gold trophy. Tap it to see the old record, the new one and the difference. The end-of-workout summary lists all of the day's records, ready to share.

On an exercise's page, in the Stats tab, tap a record to find the workout where you set it.

What is estimated 1RM?

1RM (“one-rep max”) is the heaviest load you could lift once on an exercise. It is a commonly used benchmark for maximal strength.

Musku estimates it from your sets, with the Epley formula: load × (1 + reps / 30). For example, 80 kg lifted 8 times gives an estimated 1RM of about 101 kg. That way you follow your estimated 1RM over time without ever having to load the bar to your maximum.
