You can find polarity ratio as an column option under ‘Weekly Stats’ section of the fitness planner:
Keep in mind that Polarity Ratio in Xert is the ratio of Low XSS: (High XSS + Peak XSS), so it will often be 90:10 (or greater). Don’t fret if it’s higher than the “80:20” that’s been made popular by Stephen Seiler, since that 80:20 is calculated differently than Xert’s polarity ratio. HTH.
