Not recommended for distance throwing
The Cannonball Weighted Ball is perfect for rehabilitation, toning, therapy, muscle memory, strengthening, and warm-up.
That is a great warm up ball. After using it, a normal softball feels like throwing a styrofoam ball.READ MORE
I use the Cannonball to warm up arm before slow pitch softball practice and games. Toss this thing around for a few minutes and a regular softball will feel weightless. It truly will transform your arm into a cannon. Just make sure your aim is accurate or you may throw wildly. Still I highly recommend.READ MORE
Accidentally left ours at a field. Couldn’t wait to get another one. It’s a must for any pitcher.READ MORE
I have a cannon that my uncle bought at a flea market and I loaded it with The Cannonball and it worked great. Great distance! Highly recommended.READ MORE
As advertised. Throw this thing for just a couple minutes and a regular ball will feel like it’s made of paper and, yes, you can throw harder and farther than before. Results are quick and noticeable. Highly recommended.READ MORE
Worth the investment if your daughter is 12 or older and is going to be a pitcher in high school.READ MORE
Has no grip whatsoever.READ MORE

Awesome product
Perfect!
great tool for arm strength
I coach 10U girls travel softball and am a believer in weighted balls (if the pitching mechanics are correct) so you don’t injure your pitchers arms.
Velocity is going up!
just what i was looking for.
