For those that like practice/shadow swings to simulate pro strokes, especially
@Curious, this is enough to get your started -
With a full length mirror, place a laptop on a chair or small table facing the mirror. The mirror allows your reflection and the laptop's model player reflection to have the same orientation. Position yourself so that you see the stroke on the laptop and your reflection. I was a few feet from the mirror and the laptop was closer, maybe 2 feet. I viewed the upper body (above waist) of a Gasquet backhand. I looked at single frames of the video for positions.
As I see it now, you must be viewing the mirror so you need to find videos of similar appearing model strokes. Find the pro video head looking in the direction of the camera and then orient yourself to be looking at the mirror with the same head angle as in the pro video reflection.
Put the Youtube on loop at a slow playback speed. Single frame to view body positions.
I could reproduce the body and racket positions, but I could not place my chin to the other side of my shoulder as Gasquet was doing (See Scapular Protraction). Body positions and joint motions that you cannot reach
statically will show up right away.
Note- the height of the incoming ball is a variable.
In Motion. If anyone that regularly practices shadow swinging uses this set up please post any problems and hints. Especially, I have not tried slow motion swings vs a slow motion playback of the pro player, so please post on that if you learn anything about working with slow motion.
