Roger Federer Slow Motion - Serve, Forehand, Backhand

Here is a great serve lesson notice how he load and expload in a fluid motion.
On the forehand he still looking at the ball even after he made contact and the ball left the racket . that takes a lot of displan and practice.
On the back hand contact front of your body and make sure you brush up and exaggerate your swing if you can . that would ensure the ball will dip in .
