Have you ever wondered why some people gain muscle easily, others stay naturally slim, and some tend to gain weight faster—even when eating similarly?
The answer is often linked to what is commonly called body types. While this concept is widely used in fitness, it’s important to know it’s a simplified model, not a strict scientific classification. Still, it can be helpful for understanding how different bodies respond to diet and exercise.
