"Scale training volume down for already-active blue-collar workers When trainers began working with blue-collar clients who were on their feet and lifting for ten-hour shifts, the instinct was to match their toughness with high-volume, intense programs — but clients kept reporting that they "couldn't work that well the day after" because they were too sore to perform their jobs. Dropping to moderate intensity and lower volume not only fixed the soreness problem but actually produced better fitness results, because the physical demands of the job were already providing substantial training stimulus. The actionable principle is that before designing any exercise program, you must account for all physical stress in a person's life — not just what happens in the gym — and reduce formal training volume accordingly so recovery remains possible.
