This podcast episode (Ben Greenfield Fitness, ep. 328, 2015-08-12) covers practical fitness and performance topics in a Q&A/newsflash format. Key takeaways: caffeine timing depends on delivery form (gum 20 min; beverages 35 min; pills 60 min); frequent air travel (hypermobility) has physiological and social costs; HRV interpretation requires context (sympathetic/parasympathetic balance); warm-ups of 10–15 minutes plus dynamic stretching improve muscle temperature, nerve conduction and joint lubrication; exercise-machine comparisons favor stair climbing and ellipticals over StairMaster in many cases; body recomposition is achievable with resistance training, adequate protein (≥0.55 g/lb), and moderate calorie deficits with periodic refeeds; endurance-race fueling limits exogenous carbohydrate oxidation to ~90 g/hour (~360 kcal/hr) and total practical max ~440 kcal/hr with MCTs and amino acids.
