The Instant Power Move

3. MAKE THE MAGIC MOVE
Now the fun part! About two or three feet before your hands reach impact, assertively rotate them toward the target. Imagine you're gripping a screwdriver and turning it counterclockwise. This closes the clubface, generating big-time power.

It's important to note that you can turn your hands too early (you'll hit a hook) or too late (a push), but you can't turn them too much. So really go after it with an athletic motion. Also, your lower body should stay quiet: excessive hip clearing and swiveling is wasted motion. The legs should support your upper body, not drive the swing.
YOUR VIEW
Take a look at this swing sequence from a first-person angle (go right to left...sorry southpaws). The open clubface (far right) closes through impact; the toe should almost point to the target (far left) a couple of feet after impact.
