We divide a stroke into phases to make it easier to observe. In play, preparation, acceleration and follow-through form one continuous movement. A position seen on video is useful when we can relate it to the movement that came before and to the action that follows.
Phases and key instants
Inside Out distinguishes preparation, acceleration and follow-through, with key instants such as readiness, loading, contact and the end of the movement. These give coaches and players a shared language. They also help locate when a problem begins instead of describing every error as a failure at contact.
Tracing a contact problem
Suppose a player is crowded at impact. Look at the preceding approach, turn and preparation. Did the player create space? Was the racket organised before acceleration became urgent? Contact contains information about what came before, but a still image cannot establish the cause by itself. Compare several repetitions against similar balls.
Follow-through and recovery
The follow-through includes continuation and deceleration. Its value also appears in what happens next: balance, recovery and readiness. Forcing a particular finish can hide a rushed earlier action. A long follow-through is not automatically better than a compact one when the incoming ball removes time.
Final reflection
Use the phases to locate where the sequence changes. Then check how that change affects the contact and the player’s preparation for the next ball.
