Muscle hypertrophy is closely related to resistance training, as it stimulates muscle growth through progressive overload. When muscles are subjected to increased tension through weight lifting, microscopic tears occur, prompting the body to repair and adapt by increasing muscle size and strength. Consistent, well-structured resistance training programs that focus on variables like volume and intensity promote effective hypertrophy. Nutrition and adequate recovery are also pivotal in supporting this process, emphasizing the synergy between training, diet, and rest for optimal muscle growth.
