Challenge: My students throwing motion on their serve needs work.
Solution: The Serving Sock helps players improve the rhythm and fluidity of their serve. Corrects uneven and awkward serving motions. Just swing the Serving Sock like a racquet and avoid hitting your back. If your swing is fluid it won't. Also try tossing a ball and hitting it with the sock
Note: It may be easier to start in a modified beginning position, demonstrated in the second photo in the sequence image above.
The serving sock is the same length as a tennis racquet from grip to center of strings.
