Ep. #984: Bill Campbell on the Science of Training Volume

In this podcast, I chat with scientist and friend Dr. Bill Campbell about training volume. There’s a recent trend in the fitness space that more volume is always better. Is that always true, though? And if you do want to increase your volume, what’s the best way to do it? You’re going to learn all that and more in this interview. In case you’re not familiar with Dr. Campbell, he’s a professor of Exercise Science and the Director of the Performance & Physique Enhancement Laboratory at the University of South Florida, who’s also published more than 150 scientific papers. He also recently started a research review in which he examines scientific papers and breaks them down into simple, actionable takeaways. In other words, Dr. Campbell has long been behind the scenes, conducting research on practical, fitness-related matters and helping people apply the latest findings to get us more jacked. In this interview, Bill and I talk about . . . - The right way to count volume (sets, tonnage, etc.) - The practical limits of increasing volume (and how to increase volume the right way) - The utility of “test days” and training to failure every so often - The drawbacks of training to failure (especially for athletes) - Why rest times between sets matter - How to count indirect volume for muscle groups - And more . . . So, if you want to learn what the latest science says about training volume and if you should adjust your workout programming, don’t miss this episode!
