Understanding one’s body type in fitness is crucial for tailoring *exercise* and *nutrition* approaches. Different *somatotypes*—ectomorph, mesomorph, and endomorph—affect how individuals gain *muscle*, *fat*, and respond to *exercise*. For instance, an ectomorph may require higher caloric intake for muscle gain, while an endomorph may benefit from a focus on fat loss. Recognizing one’s body type allows for more effective, personalized training plans, leading to better results and improved *motivation*.
