HOW TO SWING WITH CONTROLLED AGGRESSION
Do you think strength pays? Check Villegas's distance stats and take a good luck at his biceps. They're both huge. Strong arms, however, allow you to do more than just swing fast. Extra muscle here allows you to go as hard as you want without causing your technique to fall apart. Watch any well-built golfer and you'll rarely see them flip their hands or slide their legs toward the target through impact. If you tend to make these errors, slow down your swing or hit the weight room.

A. POWER POSTURE: Camilo has rotated his shoulders 90 degrees relative to his spine, but his back retains the angle it established at address. This is a critical key to consistent contact, especially if you're trying to ramp up your swing speed.
B. POWER GEOMETRY: Look how Villegas's shoulders and arms form a perfect triangle, and how a straight line drawn from his sternum would bisect his hands. As long as you can form this triangle at this point in your swing, you can go after the ball as hard as you want.
C. POWER PLUG: Notice how Villegas straightens his left leg. Doing this keeps him centered and allows him to rotate his hips and keep his right knee moving toward the target. Without a straight left leg, you lose torque and consistency.• More swing sequences including Tiger Woods, Annika Sorenstam and Vijay Singh
