Yann is about 5’10” and is a slender guy, but he can serve 130 mph+ thanks to his “Serve Accelerator” technique.


Inside “Serve Accelerator,” Yann shows you his 10-step process for taking your serve from where it is right now, and “accelerating” it using your body’s natural ability to coil and explode into the tennis ball.  If you’re not a big guy or gal then this is how you super-charge your serve speed.
