The Diet Doc
A technical masterclass for competitive bodybuilders on the science of contest preparation, hosted by a veteran coach and PhD.
This is a highly specific, educational podcast for competitive physique athletes and their coaches. Rather than general fitness advice, host Joe Klemczewski and his co-hosts conduct deep dives into the most technical aspects of bodybuilding contest preparation. Episodes are structured like university lectures, focusing on granular topics like peak week water manipulation, contest day pump-up mechanics, and posing strategies.
“Its distinctive feature is the extreme specificity and academic focus on the final days and hours before a bodybuilding competition. Unlike broader fitness shows, it's a coach's-level conversation that treats contest prep as a hard science, complete with case studies and physiological explanations.”
