This workout focuses on upper body sculpting, abdominal and waistline toning, strength, and cardiovascular fitness. It exercises your whole body while giving special attention to your shoulders, chest, and back. Additional core work will help improve the appearance of your abdominal region. During this workout, be cautious with your shoulders, elbows, and wrists, as many of us are not used to bearing weight with our upper extremities. This should get much better with time. Resistance training of this sort is designed to lay down denser bone while increasing the integrity of joints.
