Underload — Trainer

Speed up your swing with the Underload Trainer, a lighter-than-standard training bat handcrafted from the same premium wood as our game bats. Its reduced weight lets you swing faster than game speed, training your central nervous system to recruit more fast-twitch muscle fibers — the same overspeed principle sprinters use running downhill. Alternating between an underload and your standard game bat has been shown to boost bat speed by up to 8%, building the hand speed and quickness that carry over the moment you pick your regular bat back up.
