Wall Ball Research What Makes the Most Durable Medicine Balls?

We love testing fitness gear here at I Sell Fitness. We are big on making ISF gear more durable, more functional, and just better in every way, including keeping it all low cost with a strong warranty in order to deliver the best value out there. Our goal here is to become a leading provider of functional fitness equipment and we are in the very early stages of doing just that. 

These wall balls will be taken to failure and then dissected to compare against other brands to figure out what ingrediants make the most durable medicine ball.  We will be slamming these med balls to failure and will not stop at just the wall balls.  We'll be going hard against traditional medicine balls, slam balls, and the 14" wall ball.  Can't wait for the results.
