Back on the podcast today is Eric Helms, PhD. Eric is a research fellow at the Sports Performance Research Institute New Zealand at Auckland University of Technology, pursuing research in training, nutrition and psychology for strength and physique sport. He has a PhD in Strength and Conditioning with a research focus on autoregulating powerlifting, a masters with a research focus on protein and macronutrient manipulation for dieting bodybuilders, a second masters in exercise science and health promotion. Also an athlete, Eric earned pro status as a natural bodybuilder with the Professional Natural Bodybuilding Association in 2011 and is a powerlifter in the International Powerlifting Federation.

Today’s podcast is a Q&A, with Eric fielding questions on some of the best diet and weight lifting strategies. Eric offers an insider’s view on the psychological effects of dieting for competition and also describes some of the most popular non-linear eating strategies and who might benefit from them. He discusses the power of refeeds and diet breaks when it comes to maintaining weight loss, and explains why a flexible approach is more likely to result in long-term success. Eric also addresses the "repetitions in reserve" -based rating of perceived exertion and describes the benefit of using muscle and strength pyramids.
