In this short Hebrew monologue, Dr. Gil Joseph Shachar (M.D.) explains that the medieval scholar Maimonides (the Rambam) defined true physical exercise as movement that makes you breathe heavily to the point where speaking is difficult. This level of exertion signals the body that it is near its limit, prompting physiological adaptations such as increased lung capacity, better oxygen uptake, enhanced muscle work, new mitochondrial production, greater energy generation, expansion of existing blood vessels, and formation of new vessels. Shachar argues that casual activity goals like the popular “10,000 steps a day” are insufficient for achieving these deep adaptations, emphasizing that only intense effort triggers real improvement.
