D-Ball Medicine Balls-Keystone Conditioning and Training for Athletic Performance

Strength and power training benefits are enhanced with a single ball size spanning a wide range of weight. This means the same lifting-leverage factors will be applied consistently to the athlete’s conditioning performance. D-Ball benefits are similar to Olympic lifting. However, D-Ball places more emphasis on the core where the transfer of power linkage of the three torso components, shoulders, core and hips is similar, but the ball is held off the centerline so the core works harder to support lift and stability.

D-Ball’s Features make D-Ball Different from other Medicine Balls

Here’s why D-Balls are different:

Unique visible weight strip on medicine ball The Visible Weight Strip: An easily recognized stripe around the center identifies the ball weight.

The Yellow D-Ball (non-bouncing): Yellow D-Balls are a golden yellow and do not bounce. They have a soft grip for a firm hold to move and throw in turn emphasizing both strength and speed. D-ball is the same size over an extended range of weight. The fact that the Yellow D-Balls do not bounce adds work as it must be picked up off the ground each time it’s thrown.

Orange semi-bouncing D-Balls The Orange D-Ball (semi-bouncing): Orange D-Balls do a semi-bounce and are hunter orange in color for high visibility. They also have a hard shell which allows them to bounce, i.e. a hard bounce or dead bounce so that physical work can be seen. Moreover, the high visibility of the color means quicker reactions and speed resulting in better performance and reducing the risk of injury from a flying weighted ball. It takes a strong effort to produce a good semi-bounce. Semi-bouncing Orange D-Balls are the same size and weight within a moderate range and can be interchanged with the Yellow D-Balls, as with the Keystone ball for example.

The Shell Texture: The ridges and roughed up texture are for grip. They act like the seams on a baseball for throwing. The D-Ball’s thick, tough shell is guaranteed to last or we replace them. You can pound D-Balls and they feel better because they have self-adjusting air pressure.
