Andy Galpin is the muscle guy Huberman keeps inviting back because he will tell you the dose. PhD in human bioenergetics. Fifteen-odd years running an exercise biochemistry lab at Cal State Fullerton, then in 2024 the Human Performance Center at Parker University. He coaches people whose job is to win (fighters, Olympians, CEOs who treat a board meeting like a final) and he still talks like a prof who has graded too many vague training logs.
The useful Galpin is specific. How many hard sets per week actually grow a muscle. What VO2 max work looks like if you are not a 22-year-old rower. Whether you need a fiber-type biopsy (almost never). Sleep as a performance drug, not a vibe. Protein as grams you can count, not a brand of powder. His Perform podcast is the long version of that: mechanisms, then a number you can put in a calendar.
He sits next to Attia on this site and they do not quite do the same job. Attia is the 40-year healthspan plan. Galpin is the session. If you want to get stronger without turning into a spreadsheet cult, he is the cleaner read. Pair him with resistance training and ignore the part of the internet that wants a new periodization religion every quarter.
He sells coaching and a newsletter. That is the business. The free episodes still give you more programming literacy than a $200 hypertrophy ebook. If a cue only works for a world champion with a chef, he is usually the first to say so.
