How strong is a 100 kg bench press?

A bench press number only becomes useful when it sits inside a training history: bodyweight, repetitions, technique, range of motion and recent consistency all change the meaning of the lift.

AARU is built to preserve that context by recording sets, load and performance history, then making progression easier to read over time.

For an estimated one-rep max, use the calculator in Strength Lab. For official exercise ranks, use the AARU app rather than a recreated public formula.
