Carbohydrate, Water, and Electrolyte Manipulation For Physique Athletes

The Stronger By Science Podcast

In today’s episode, Greg and Eric explore the art and science of “peaking” for physique athletes. The discussion covers carbohydrate loading, water intake adjustments, and electrolyte manipulation for the purpose of transient physique optimization. This conversation digs into the limited research available, while also providing practical recommendations guided by a combination of scientific evidence and real-world experience. Finally, Greg and Eric close out the episode by unanimously recommending a TV show that aligns with the values of the Stronger By Science Podcast.
