Training device for throwing a ball

A throwing exercise apparatus including the combination of:

• a sphere having an exterior spherical surface containing first and second diametrically opposed access sites to an internal polar passage;
• an elongated anchor strap having a first strap mid portion traversing said internal polar passage and strap end portions interconnected by a fastener at said first access site to said internal polar passage, said elongated anchor strap having a second strap mid portion wrapped against a part of said exterior spherical surface of said sphere between said second access site and said first access site to establish a path of elastic resistance along a tangential line formed by the wrapped part of said second strap mid portion in response to an applied force comprising both translation and rotational motions of said sphere, said elongated anchor strap having a width and a thickness creating sufficient bulk to insure a long continued static relation with said sphere by transforming from a rolled shape in said internal polar passage to generally plainer configurations along said second strap mid portion and said strap end portions;
• and
• an elastic band anchored to a static structure at one end and joined to said strap end portions interconnected by said fastener to provide progressive resistance by said rotational motion of said internal polar passage and by said translation motion to the wrist and forearm musculature during multi axial and multi planer motions delivered through the ball elastic resistance provided by said elastic band.
