This video looks at using mainly body weight exercises with a some inexpensive gym equipment that will tone and build muscle in the upper body areas.
Some of the exercises demonstrated are: Pushups, Chin-ups, Pull-ups, Shoulder Press, Shoulder Raises, Bicep Curls, and Triceps Extensions.
Not all of these exercises can be done by only using your body weight, but by adding some inexpensive Dumbbells and a Chin-up bar, all of these exercises can be achieved.
