How intense is combat training?

Combat training, as described in the podcast "My First Million," involves a very intense and demanding regimen. According to Shaan Puri, army training includes a rigorous schedule of calisthenics, marching classes, weapons training, and athletics. Trainees engage in these activities from 5:00 AM to 10:00 PM without any breaks, weekends off, or contact with family or friends. This level of intensity demands significant physical and mental commitment from participants 1.
