A golf swing requires a controlled but aggressive weight shift. Still, some players get stuck on the right foot and never fully shift, causing many of the typical bad-shot blues. Try teeing a ball and taking your normal address position. Now, bring the left foot back so the feet are about 6 inches apart. Take a normal backswing, but just as you begin down, step forward as though you are a home run hitter stepping into a pitch. To hit the ball solidly, you might need to tone down the swing a bit. This not only gives you a real feeling of shifting, but it also trains you to repeat it.
