I have never been much at throwing a ball. Although it never mattered much I just figured I couldn't because I didn't have the strength

You guys make it look so easy.
But I have a big healthy dog and she loves it so I've been really thinking about "what is the secret?" I mean I was
lame!
15 feet was about my max. I would throw it down the hill so it would go farther and she got a better workout coming up the hill.
For a couple weeks I thought about how to build a dogie ball catapult

(I still think there is a market for that) Just hit the peddle with your foot and it lobs the ball

I was going to post and see what we could come up with.
But I continued to throw these stink balls and started thinking about my grip. Hmmm it feels like it's rolling off my fingertips back wards. Hmmmm I must be releasing it the wrong time when I throw....
EUREKA!!!!!
You have to hang onto the ball tight and then let go!!
I never gripped the ball tight.. Never occurred to me, after all I wanted it to fly didn't I?
I had a very loose grip on it thinking it would get better movement with less finger friction
You know no one ever really tells most girls how to throw..
I'm now tossing those puppies an average of 50 feet! w00t!! and my dog says w00t!
Any more tips are appreciated
