Wow next gen

Well explained, well edited. Thanks! Albeit the problem in the reality of recreational player is that you should not (and actually cannot) move in check lists. In the end, it must be a fluid motion where everything works bioechanically together as required by the current situation. This situational awareness , i.e. the capability to foresee the trajectory of the ball, is one the secrets why professionals seem so fast. They interpret the way the opponent moves and sets up to anticipate the next ball. This, however, comes from pratice in countless hours since their youth...and their is no shortcut to it. Having said this, there is always something to take away from watching the pros in vids like this. However, most players should at first record themselves to understand what they are actually doing and not what they believe they are doing. This can often be very disillusioning.

what program do you use to view the video this way?

The free arm is more about bringing the racquet back and coiling the upper torso than spacing.

Thx for the great vid. It explains everything except the wrist? Does he keep firm 90° degree at the impact or uses his wrist(snap?) at the contact? Thx again

there is an information I haven't found yet: what kind of raquet grip Alcaraz use? It doesn't seem to be an Eastern grip.

The contact is depend on the ball.
