@cougars- one of the best workout plans is the one that many boxers use. You can go to your local library and borrow a boxing training DVD to get an idea of how to put together a balanced calisthenics routine. These types of routines build raw power and are some of the healthiest workouts you can do.
Personally, I believe they make you stronger than gym workouts because they force you to use your stabilizer muscles. You are also forced to use muscle combinations that are used in everyday movements. Smith type machines may sculpt the body, but often times, those guided movements would be awkward in normal life.
