This little application tries to predict the maximal strength (1RM) based on a repetitions to fatigue (RTF) value.

The calculation is based on the so called KLW formula:

$1RM = w\cdot(0.988+0.0104\cdot x+0.00190\cdot x^2-0.0000584\cdot x^3)$

The horizontals axis denotes the number of repetitions, the vertical axis denotes the ratio 1RM/RTF.
