Muscle Hypertrophy Theory

Muscle hypertrophy theory explains how muscles grow in size through resistance training. When muscles are subjected to stress, like lifting weights, tiny injuries occur in muscle fibers. The body repairs these fibers, making them thicker and stronger. This process is influenced by factors such as exercise intensity, volume, nutrition, and rest. Key hormones like testosterone and growth hormone also play a role. Essentially, consistent and progressive resistance training, combined with adequate nutrition and recovery, leads to muscle growth over time.
