A common misconception regarding muscle building is that lifting heavy weights is the only effective method. While lifting heavy can induce muscle hypertrophy, progressive overload can also occur with lighter weights when performed with increased repetitions or intensity. Additionally, proper nutrition and recovery are crucial for muscle growth. Understanding that a variety of training techniques, such as bodyweight exercises and resistance bands, can also contribute to building strength is essential. It's the combination of multiple factors, including consistency and technique, that leads to effective muscle development.
