What should I do to improve my tennis serve?
To improve your tennis serve and add power to it, it takes a lot of practice and patience. With constant practice, you can effectively add power to your serve. This can be perfectly done by applying pronation to your serves by making minor adjustments to add smaller levels of torque to your shots, gradually building up to a complete extension and adjustment in your swing.
Always bear in mind that it takes a lot of practice to effectively execute pronation and add power to your tennis serve. So, before utilizing this technique in every game, spend a lot of time practicing the adjusted swing.
