Pete Sampras had a great forehand. Many he said he had one of the best on-the-run forehands of all time. Sampras hit the forehand very flat and he DROVE through the ball often to devastating effect. His clean hit and clean swing on the forehand side also allowed him to develop a clean attacking approach shot.
Sampras uses what is known as the “Lansdorp Forehand” it uses a classic grip and does NOT use heavy topspin or a western-grip. Robert Lansdorp is a famous coach who is a living legend. He trained Sampras and Davenport and Tracy Austin and Maria Sharapova.
If you want to read some interesting opinion on training I would check out the blog that Robert has (or maybe used to have): https://robertlansdorp.wordpress.com/philosophy/
Lansdorp he stresses “Discipline” and he is big on the players being focused. He also wants the players to spend a lot of time on repetition. Some might say “ball after ball after ball” He has a “tough guy” approach and he demands discipline of the player. I think Lansdorp is a great coach and his track record really speaks for itself. I am sure he has rubbed many people the wrong way throughout his life BUT I can say for sure, that now, in a time where American tennis is looking weak … and people are asking “where are all of the champions?” People need to be looking at Robert Lansdorp and his teaching approach.
