The "minimum effective dose" concept in fitness training posits that there is a threshold of exercise intensity and duration necessary to yield health benefits. This principle suggests that achieving fitness goals does not always require excessive training; rather, a well-structured, efficient regimen can be just as effective. By focusing on this minimum dose, individuals can streamline their workouts, prevent burnout, and improve adherence to exercise routines. Understanding this concept allows for the creation of sustainable fitness plans that align with personal schedules and lifestyles.
