How do Federer and Henin get so much power?
There are many aspects of their technique that result in the devastating power we so often witness. One secret at the heart of this power is knowing how to generate more racquet head speed.
The tip of the racquet travels with such speed that it overtakes the position of the grip as soon as the ball is struck. In other words, on impact the racquet head and grip are pretty level, but right through contact the racquet tip zips through at the rate of knots and overtakes generating amazing power. Of course, the shoulder rotation, ball position, leg foundation all play their part in this power.
