Recently I was asked if I could only do three exercises, what would they be?  After some consideration, I said I would do pullups, pushups, and barbell squats.  I explained that if you combined these three exercises in a workout you would hit all the major Muscle groups of your body
Let's look at these three exercises and see if they would be a complete whole body workout.

Pullups target the major muscles of the upper back, the biceps, and the forearms.  The core muscles also work to stabilize your body to keep you from swing as you pull your body up and lower it down.  Take a look at the video below to see a properly executed pullup.
