Partial ROM, Intra-Workout Carbs, MASS Research Roundup

The Stronger By Science Podcast

Today’s episode begins with a reminder about the current Black Friday Sale for the MASS Research Review, which ends November 29. After that, Greg and Eric share updates regarding their dueling Road to the Stage and Road to Athens segments. Next, Greg delivers the Feats of Strength segment, which features a legend in the world of iron sports. After that, Greg and Eric discuss some of their favorite MASS articles from the past year or so, with topics including p-ratios, plant-based protein, carbs for lifters, effects of diet on testosterone, emerging supplements, partial-ROM training, the interference effect (concurrent training), and muscle damage. Finally, Eric answers some listener questions about soy protein and intra-workout carbohydrate, then closes out the show by recommending some focus-enhancing music to play while you work.
