Ep 327 - Fat Loading, Sodium Limits, and More

First they share updates on Front Page Fitness and discuss some soon-to-be-released articles from the Mass Research Review, with topics including the implications of cold exposure, how much testosterone actually impacts muscle mass, seed oils, the effects of ketogenic diets on blood lipids, and eccentric training on muscle growth. The conversation also touches on the effects of alcohol consumption, navigating excess skin after weight loss, fat loading, sodium intake, meditation to acutely impact lifting performance, the effects of creatine supplementation, circuit training, and much more.
