1RM (one-rep max)

LiftShift may show 1RM estimates derived from logged sets.

What a 1RM estimate means

A 1RM estimate is a calculated approximation of your one-rep max based on a submaximal set. It is useful for tracking direction over time, not for proving a true competition max.

Limitations

• Different rep ranges can produce different estimate accuracy.
• Changes in technique, tempo, or range of motion can change comparability.
• Estimates should not be treated as medical or coaching advice.
