When counting how much you lift, giving partial credit to exercises that work multiple muscles at once (like squats) gives the most accurate picture of your training load.
Scientific Claim
The findings of this meta-regression support the use of the 'fractional' quantification method for estimating resistance training volume in future research and training prescription.
Original Statement
“The relative evidence for the 'fractional' quantification method was strongest; therefore, this quantification method was used for the primary meta-regression models.”

The Resistance Training Dose Response: Meta-Regressions Exploring the Effects of Weekly Volume and Frequency on Muscle Hypertrophy and Strength Gains.
The study found that counting workout sets using the 'fractional' method (giving partial credit for exercises that indirectly work a muscle) gave the best results for predicting muscle and strength gains, so it’s the best way to measure training volume.
