1. Simply position the ball (using a holder) and place your plant foot exactly in the location it needs to be for you to make proper contact.
2. Now draw your kicking leg back, striving to position the foot directly behind you (as high as you can) and (at the same time) extend the arm (opposite the kicking leg) out and away from your body. At this point, you are preset to perform the drill.
3. Kick through the football and simultaneously bring your arm (opposite the kicking leg) across your chest in a parallel and upward "sweeping" motion. At impact, your hips should square up in the general direction of the target. As your foot goes through the ball and your kicking leg reaches maximum follow-through, your hips should continue forward in a "thrusting" motion enabling optimum power through the ball.
4. As this transfer of energy takes place, the body compensates this movement by allowing the plant foot to lift very slightly off the ground and "skipping" forward. Due to the torque of the body, soccer-style kickers generally skip to an area ahead and away (outside) from where the plant was made (with the toes pointed slightly in the same direction). Straight-on kickers will simply just "skip" straight ahead toward the target.
5. Make sure you keep proper body lean (chest over knees) throughout the entire kick. The head remains down with eyes focused on the ball as you kick through it. There should be no "jerking" downward with the head as you kick the ball. Your head should remain on a smooth, steady plane as you approach the ball and should remain in this same attitude throughout the entire kick.
The higher you can draw the leg back, the more you enhance the "whipping effect" (leg speed) of the kick. It's not how strong your leg is that determines power. it's how fast it is (when making contact with the ball).
