In the human body there are three muscle groups. The smooth muscle covers organs such as the spleen, liver, etc. The cardiac muscles are the muscles within your heart. The skeletal muscles are the muscles that allow for movement. There are many different exercises that can be done, each one working out something different in the body. All exercises should be comprised of a warm up period, a comprehensive exercise period (main workout), and a cool down period. The warm up should consist of 5-10 minutes of a mixture of stretching and low cardio exercise. For the comprehensive exercise period there should be about an hour of more intense cardio followed by if wanted a 30 minute weight training period. Finally there should be a 5-10 minute cool down period consisting of light cardio followed by stretching. The length of your exercise routine creates the type of workout you receive. A longer work makes you tired, when you are tired your muscles have to work harder and that is when you truly get your workout.

They have very little body fat, and are genetically gifted tending to become body builders. They have long torsos, full chest,
