The "Upper Body" refers to the part of the human body that includes the chest, back, shoulders, and arms. This area is crucial for many daily activities, such as lifting, pushing, and reaching. The muscles in the upper body, like the pectorals and deltoids, help us perform tasks and maintain good posture. In addition to muscles, the upper body also contains important organs, such as the heart and lungs. These organs are protected by the rib cage and play vital roles in our overall health. Strengthening the upper body through exercises like push-ups and pull-ups can improve both fitness and functionality.
