Get Game Ready. Anytime, Anywhere! Take your game to the next level by training with Towel Trainer! The Body learns through repetition: Towel Trainer gives you the reps necessary to achieve consistency and make lasting changes in your throwing motion. Feel the difference compared to the traditional towel drill towel. Preferred by Pros, the unique design of The Original Grip Handle and Powersleeve focuses the energy of your delivery, enhancing the ability to "feel" your mechanics and release point. The Original Grip Handle also allows you to practice throwing using any of your grips, regardless of your hand size (from Youth Leagues all the way to the Big Leagues). Train Anywhere, Anytime. Practice throwing without a catcher, without a mound, even in your home, rain or shine.
