Muscle building, also known as hypertrophy, is the process of increasing muscle mass through exercise and nutrition. This typically involves resistance training, where muscles are challenged by weights or bodyweight exercises. When muscles are stressed, they undergo repair and growth, leading to increased strength and size over time. Nutrition plays a crucial role in muscle building. Consuming adequate protein, found in foods like chicken, fish, and beans, helps repair and build muscle tissue. Additionally, a balanced diet with carbohydrates and healthy fats supports energy levels and overall health, making it easier to engage in regular workouts.
