How do you know if you're training hard enough? Is there a low-end threshold for maximizing muscle growth? Should you train to failure "just in case"? In addition to answering these questions, I'm also analyzing the RPE (or RIR) of some bodybuilders including Jay Cutler, Chris Bumstead, John Meadows, Kai Greene, Ronnie Coleman, Alberto Nunez, Greg Doucette, Matt Ogus, Stefi Cohen and Sunny Andrews. I also discuss what the science says about the relationship between proximity to failure and rep speed. Enjoy!
