The general method of training volume is nothing more than extending the time and intensity of training, but the lungs are often ignored. To improve the body's function and capacity, not to strengthen the time, but to exercise the lungs and respiratory muscles (such as the diaphragm and chest expansion muscles) to improve the quality of each workout and maximize the body's potential.
