Consistency gives progress something to build on
ACSM’s 2026 guidance emphasizes regular participation and adapting a plan to the person and goal. You do not need a complicated system to begin understanding progress. The progressive-overload guide explains how to compare sessions without confusing a bigger number with a better task.
Keep the broader activity picture visible
CDC adult guidance includes both aerobic activity and muscle-strengthening work. Recovery, food, and sleep help explain the setting in which a plan operates. A supplement can be an additional consideration without becoming the center of the training map.
