Product Description

Endorsed by Pittsburg Pirate's General Manager Clint Hurdle, the Hitting Jack-It is the only weighted hitting training system that you can actually use while taking live batting practice. Developed by ball players, for ball players, the Hitting Jack-It will quickly develop bat speed, power, and force your hands to work properly for improved technique.

Patent pending design places the Hitting Jack-It in the optimum position at the mid-point of the bat rather than around the barrel like traditional donuts, sleeves and sand bagsAllows the bat to stay balanced during the swing and avoids 'casting' that can happen when weights around the barrel are too far away from the handsPlus, with the barrel of the bat open you can take live batting practice or hit off a tee with the Hitting Jack-It on the batThe small 9-ounce size develops bat speed and works your body's fast twitch musclesThe medium 12-ounce size strengthens the hands and forearms to improve muscle memoryLastly, the heavy 16-ounce size develops power by engaging the larger muscles of the shoulders, back and torsoThe Hitting Jack-It works with all baseball and softball bats and allows players to develop their swings during live batting practice sessions
