A power-building exercise is any physical activity that aims to increase strength and build muscle. Synonyms for this type of exercise include strength training, weight lifting, resistance training, and muscle-building workouts. These exercises involve using weights or bodyweight resistance to challenge the muscles, which then respond by becoming stronger and more toned over time. Other synonyms for power-building exercise may include hypertrophy training, bodybuilding, and high-intensity interval training (HIIT). Regardless of the terminology, it is important to incorporate such exercises into one's fitness routine to improve overall health, increase metabolism, and promote an active and healthy lifestyle.
