Training volume gains follow a hyperbolic curve, with diminishing returns beyond seven to eight sets per workout.

“The relationship between both intensity and volume of how much you do work in the gym, especially volume is curve linear and hyperbolic. If you do one set close to failure, you get a lot of gains. You do three sets close to failure, you get substantially more gains, but not three times as many gains. Yes. You do five sets close to failure and you do just a little bit better than three. You do seven or eight sets close to failure in one workout and it's statistically undifferiable from five.”
