There are primarily two areas to a person's fitness and health development. One is 'Cardiovascular Training', and the other is 'Strength Training'. Cardiovascular training is mainly working internally on gland and organ strength. A person's outward appearance can also change in the area of weight loss, and overall muscle toning with less body fat. In contrast, strength training mainly focuses on skeletal muscle and joint strength. The outward change is an improvement in a person's level of strength and the shape of their body. Both areas of training are important for an optimum level of fitness and health. In this article we are going to begin exploring cardiovascular training and its life-giving benefits.
