Driveline Baseball PlyoCare Balls - Weighted Pitching Training Balls + Free 16-Week Program

Great training device for pitchers. Helps build strength and increase velocity over time. High quality compared to other brands.

I bought these for my 16 year old son, who is a pitcher in high school and travel ball. These playoffs balls are of great quality in very durable. There are weighted perfectly and have a very good grip. He uses them year round for arm conditioning and also as part of his warm up routine before he goes into pitch. Highly reccomend.

We have 2 sets of these! Quality product with GREAT results when used like it says. Driveline produces great results but you have to be consistent. One of my sons increased his velo 5mph (to 90) and the other 3 mph to (92)!

I bought these for my oldest grandson to practice his throwing. He has used them and is very impressed with how they are helping.

Great purchase! This is the second time we have purchased this set. My son lost a few from the previous set. It comes as listed and shown in pictures. The program is good and can be used. Perfect gift for a baseball player looking to improve his game to play at the next level

Grandson loved the gift. Will help with training.

Great product. My sons uses these before each practice and game

We received 2 x 150g (yellow) and are missing a 100g (grey) ball. Not sure how to get in touch to rectify this. The 100g is required.

Durables y de calidad

迅速な対応でありがとうございました。

Todo excelente!

投手歴15年の社会人プレーヤーが緊急事態宣言中に使用してみた。MLBでの取り組みを参考に実践。ボールの重みを感じて投げる事ができる。トレーニング後に硬式ボールを握ると子供のおもちゃの様。 尚、練習場所は考えた方が良い。コンクリートに向かって投げていたらボールの空気が抜けてくる。（max 143km/hの全力投球） 学校施設の壁を凹ませて謝ったのはここだけの話。
