By lifting the barbell, muscle growth can be stimulated, muscle fibers can be strengthened, and muscle strength and endurance can be increased. Whether it is men or women, long-term practice with barbells can make muscles more developed and firm. Barbell exercises can shape and modify muscle lines, making the body more symmetrical and beautiful. By choosing the right weight and movement, specific muscle groups can be trained to achieve personalized fitness goals. Moreover, when doing barbell exercises, especially when performing whole-body compound movements such as squats and deadlifts, the cardiopulmonary system needs to provide more oxygen and energy, thereby improving cardiopulmonary function.
