Exercise frequency plays a crucial role in muscle adaptation. Regularly stimulating muscles through consistent workouts promotes the process of hypertrophy (muscle growth) and adaptation. When muscles are challenged frequently, they become stronger and more efficient, adapting to handle increased loads over time. Conversely, infrequent exercise can lead to insufficient stimuli, impairing muscle development. A frequency of training each muscle group 2-3 times per week is often recommended to optimize adaptation and strength gains. Therefore, maintaining a consistent and adequate exercise frequency is essential for achieving muscle growth and overall fitness progress.
