  • Patent number: 7670238
    Abstract: A novel ball hitting training device configured to hold two bats together in a secure configuration. Also provided is a method of using the device to increase bat speed; strengthen the arm, core, and grip; and improve, and receive feedback on, bat swing technique. The training device allows the user to assess if his hands and grip are optimally positioned to deliver maximum power to the ball upon contact. The device provides two pockets, each having a bat handle end and a bat head end. The pockets are connected to each other between the bat handle ends and the bat head ends. Each bat handle end includes a bat handle opening, such that each pocket can receive a bat through the bat handle opening. A fastener near the bat handle end cinches the device around the bats, which may allow for the twisting of the bats such that the handles are touching and the knob of one bat is closer to the bat handle openings than the knob of the other bat.
