5" Small Ball Weight: 2.5 lbs Advanced: All Starter boards Beginner: Turbo, Powder Freestyle and Surf Original Perfect for: one handed throws and shoulder stability DESCRIPTION Slam It To Outer Space: 5" Small ball will rocket out of this world when you slam or bounce on the ground or into the corner. A fast ball for an overhead throw and jumping rebound to regain control. The higher you throw the greater the rebound and bounce off the ground. Keep your focus on this ball before it takes off. Get A Grip: This ball easily fits into the palm and improves grip strength to throw and catch. Light enough for one handed tosses and plenty of rebound for shoulder stability as you maintain your arm position. A great ball for shoulder windmills and warm up before activity. Unwind Yourself: Throw easily in basic punch and overhead skills. Learn how to block, rotate and coordinate your body in the opposite motion. This helps unwind your body and will ultimately lead to better coordination overall. You might feel awkward at first, but training your non-dominant side is important for body symmetry and function.
