offical plyo set MARV TRAINING plyo balls Every Weight That Comes with ithere. Condition is Used. Shipped with USPS Ground Advantage.

-yes i have used these plyos before. I have thrown them under 10 times/sessions/warmups. As we know weighted ball routine is needed for pitching.

weather you go on a program with the plyos or use them to warmup, a weighted ball set is needed for every pitcher. I bought these this year, they took a while to come in and now I am offically retired (done playing juco) and working. Looking to sell as i no longer need.
