# Predicting maximal strength

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*:

- [math] 1RM = w\cdot(0.988+0.0104\cdot x+0.00190\cdot x^2-0.0000584\cdot x^3) [/math]

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