This month we are offering a special on our burst-resistant quality Fit Balls in our online store. The balls go for $24.95 and are essential for surf-specific training. You can get cheaper, flimsier balls, but they lose their shape quickly and are more likely to burst. Get a quality ball like a Fit Ball. And you can get the ball and one of our DVDs and really save. Check our store today.
