The term "Left Muscle" typically refers to the muscles located on the left side of the body. These muscles play a crucial role in various physical activities, including movement, balance, and strength. They work in coordination with the muscles on the right side to enable actions such as walking, lifting, and bending. In the context of fitness and rehabilitation, focusing on the left muscle group can help address imbalances that may lead to injury or decreased performance. Exercises targeting the left side can improve overall strength and functionality, contributing to better physical health and athletic performance.
