I sell a sports simulator that looks at your stroke and says what you need to change, to sports players, for $60 a month.
Record your stroke, watch it slow-mo, and get told exactly what to fix. Plain-spoken, no fluff.

Pick a moment of the sample tennis serve below to see the kind of notes the simulator gives. This is an illustration, not a real analysis.

Ball toss
The toss drifts behind your hitting shoulder.
Release the ball a little farther in front of you.
Try five tosses without swinging. Let each ball land just ahead of your front foot.
