Patrick Mouratoglou produced this clip on the two-handed backhand. The thing that’s cool about this is that he shows how to prepare, and adjust for a high ball and for a fast ball, and what causes lateness on a shot. He also discusses how to throw the racquet through the ball and the critical use of the left hand for a right handed player. For a lefty, the right hand controls the ball. Another topic he’s discusses is the looseness of the hands. This looseness assists with timing, smoothness, and racquet speed, all key components of solid striking. This style of hitting is quite common on the WTA tour with various varieties of it: youtu.be/WNnW9Dd2vMY
Simon from Top Tennis Training has produced a great video on Novak Djokovic’s two handed backhand which is considered by many to be the best on the ATP. I would say this differs from the WTA two-handed backhand in several respects, though the fundaments are the same.
