Day 6 is HUGE!
I believe a killer slice serve is the "Biggest Serve Weapon" you can Easily develop.
It does not matter your age, height, or skill level you can own this serve and it completely changes you as a player!
You will be sought after to play on every team at your club.
True story this happened to me yesterday.
I was playing doubles with another Teaching Pro friend named Chris, against some of his teammates at the Club.
I left after the match and my partner stayed behind with our opponents.
Today my friend Chris said after I they were asking all kinds of questions and wanted me on the team because of my Slice Serve.
He told me to "expect a call".
The slice serve can completely dominate a match in doubles.
It creates tons of FREE points because your opponents will keep pulling the ball wide.
And gives your partner TONS of easy put away volleys.
I barely had to volley the entire match because it is very hard to hit a good slice serve past the net person and solidly cross court.
This makes holding serve ALMOST a joke!
What is lucky for you is I now think I am getting better at teaching the slice serve then I am at hitting it!
I have NEW never seen before progressions that will have you slicing the serve right after your first practice!!!!
