muscular

A muscular person has strong muscles and good physical fitness.

You hear this word often when talking about sports or exercise. When a coach says "Our team has more muscle" they mean that their players are physically fit and have strong bodies to compete well on the field. If you're training for a marathon, you might aim to become more muscular by doing exercises like weightlifting or bodybuilding. Even in everyday conversation, someone might say "I'm feeling quite muscular today after my workout", meaning they feel energetic and confident.
