Birsppy mcyiqihai ProNine Heavy Weighted Training Baseball Ball for Pitching and Throwing Practice (10 oz)

Use for building arm strenght.

Purchased this for our son who plays 12U. He uses this to warm up and then to work on his arm strength. He doesn’t use it all the time, but will add it into his warm up. He also uses it for long toss.

Does the job...strengthens the throwing arm

Tossed this back and forth with my kid for 20 mins a day during the off season. Great warm up, keep my shoulder loose and made the kids arm stronger.The ball is pleather but it does last and still looks new after weeks of use. My only concern was making sure the kid watched the ball all the way in to the glove, you don't want this ball to be missed, it would break a nose or pop a tooth.

I thought this product would help young baseball players strengthen their arms so they wouldn't hurt them selves by over throwing or throwing too hard. I play Catch with my grand son using the weighted ball. We have started at a distance of 8-10 feet with slow overhand throws.WE take about 20 throws then use regulation weight ball while catching the regulation ball ,I can feel the force of the ball slowly increasing. If he continues to show improvement I will review again.

Works perfect for getting warmed up. Good quality. No complaints.

Great training ball.

Good product.. What I was looking for..
