Like weightlifters, people who are MUSCULAR, fizady, and MUSCLY have the ability to lift heavy weights and build strength. These terms refer to people who have strong and well-developed muscles, often as a result of regular exercise and weightlifting. MUSCULAR people have the capacity to lift heavier weights than those who are not as physically fit. Fizady and MUSCLY are two words that are often used to describe people who have a lot of muscle mass.
