Erin O'Brien: Strong Body, Ageless Body

The fitness release Erin O'Brien: Strong Body, Ageless Body begins with the axiom that strength training and muscle development are not simply desirable, but essential in achieving and maintaining a healthy and youthful look as one ages. The muscles, as fitness trainer O'Brien reminds us, protect such areas of the body as one's dorsals, bones, cardio regions and ligaments. Working from this concept, O'Brien presents a 45-minute aerobic routine that targets and vigorously develops muscle groups in the upper and lower regions of one's physique, including the arms, legs and abdominals.
